Before ANY motion — the checklist + +Run through it every time, and state the answers in your reply in one short block (a line per +item, quoting the tool result — not an essay): + +1. **State.** `get_connection_status` connected; `get_position`: `reliability` is `verified`, + `heartbeat` or `cached-offset` (never `awaiting-resync` or `stale`), `warnings` empty, + `isHomed` true, `machineStatus` idle. `get_stored_state` for landmarks, limits, geometry. + Not homed → homing is itself a motion (law 1), and it also homes B: stock on the rotary + rotates — say so before staging it. +2. **Frame.** Every number you plan with is MACHINE frame, or the job declares the WORK frame + and the MCP resolves it (§2). Never convert a file's coordinates by hand. No bare `Z`. +3. **Height.** Any XY move over 1 mm runs at or above the MOTION FLOOR — machine **Z320** + (`mcpMotionFloorZ`; a head reading 319.96 is at it). That is not the same number as the PARK + height, machine Z328 = home, which is where procedures hop between stations, retreat to on an + abort, and end. If the head is below the floor, the retreat is its own `move_z` step and needs + its own word from the operator: ask "may I raise Z first?" — a transit request is not + authority to move Z. +4. **Obstacles.** The same `get_stored_state` call: does the path — the whole SEGMENT from + where the toolhead is to where it is going, not the destination point — cross a landmark box + below the toolhead Z it demands? Read `requiredToolheadZ` on the landmark rather than working + it out: for a box stated with `obstacle_top_z` it is the top plus the fitted tool plus a 5 mm + margin, and for a legacy `clearance_z` it is that number as it stands. The test is + at-or-above, so equal passes. A box the operator states in chat is a planning obstacle + immediately; write it with `set_landmark` only when they ask; if chat and the store disagree, + stop and ask which is current. +5. **Tool.** A tool or the probe is ALWAYS in the spindle. Where is its tip at the Z you plan? +6. **Authority.** An explicit imperative in the operator's LATEST message is necessary — not + sufficient. It authorises STAGING; the click on the confirm page authorises the motion. An + imperative on a rejected or stale position ("home it to fix the reading") is still refused + by the tools, and you say why (§3). **Staging is half a call.** Every staging tool is + followed by `start_gcode_job {job_id, wait_for_approval_ms: 110000}` — the call that puts + the confirm page in front of the operator and runs on their click. A plan that stages and + never starts is a plan that never runs: write both calls or neither. +7. **Ask once.** Before staging anything, list every unknown the whole procedure needs — the Y + of a feature, a diameter bound, a clear Z, what an ambiguous word means, which tool-change + flow — and ask them in ONE message. A question per turn is the most expensive mistake an + agent makes on this machine. If the prompt already answers everything, ask nothing. A + question you ask is a question you WAIT for: the first tool call that uses an answer comes + after the answer, never before it. + +**Fast path.** For a transit that starts at or above Z328 and writes no Z, `get_position` + +`get_stored_state` discharge items 1–5 in one breath: quote the two results and stage +`traverse_xy` (§8). One approval, no questions. + +## 1. The eight motion laws + +1. **One motion per instruction, and no inferred approvals.** When the operator enumerates + steps, execute exactly the step they name and stop. NEVER chain motion calls in a single + command (`&&`, one script, one turn) — each motion needs a decision point in front of it + (appendix A, incident 1). A motion mentioned in passing — "take a photo before homing", + "then we'll traverse", a plan they approved — is context, not a command: announce it and + WAIT for the word. **Resolution with law 6**: a request that names a procedure ("scan the + tailstock", "probe along X from 164 to 176") authorises STAGING that procedure; the confirm + page is its decision point. A staged program or procedure is ONE decision point for every + move inside its approved envelope — that is the efficient lawful form, not a violation. +2. **X/Y traverses happen at or above the motion floor — ALL of them.** Any XY move over 1 mm + is planned at or above `mcpMotionFloorZ`, default **machine Z320** (a head reading 319.96 is + at it). No "local hops" above a measured top, no other "measured safe" height (operator, + 2026-09-02: "x/y motion over 1mm is never below gantry height"; revised 2026-09-19 from a + single height to a floor). Retreat Z FIRST, traverse, then descend at the destination. The + only sub-floor XY motion is fine positioning of ≤ 1 mm and the in-procedure envelopes in §4, + which the operator approves on the confirm page as part of that one tool call — the NEXT + motion starts from a full retreat again. Enforced: `traverse_xy` and direct XY moves below + the floor are refused; `operator_confirmed_clearance` exists for emergencies on the + operator's explicit words, never for planning. + + **The floor is not the park height.** `mcpSafeTraverseZ` (machine Z328 = home) is where + procedures hop between stations, retreat to on an abort, and finish; that is unchanged, and + `planRaiseToTop` still targets it. The floor could only drop below it once clearances stopped + carrying tool length (law 4): a hop at the floor is checked against every stored landmark + exactly like any low segment, and there is still **no exemption for being high**. What it + costs is 8 mm less blind protection for anything on the bed with no landmark — which is why + an unmapped object taller than the floor minus the tool is the operator's problem to state, + not the guard's to catch. +3. **Never fabricate clearance.** Only measured numbers or operator-stated numbers count for + heights. A photo FINDS things, it clears nothing (incident 1). An unknown height is measured + from a proven-safe height by a sensor-gated −Z march (§8 example), never assumed — and never + fed as `start_z_machine` from an operator's rough guess when a march can measure it first. +4. **Landmarks are obstacles, and a clearance is the OBSTACLE's height.** Stored landmarks are + CROSSING obstacles: an XY segment that enters or leaves their box below the toolhead Z it + demands is refused — at staging for procedures, at call time for direct moves. State a new + one with `obstacle_top_z`: the top of the obstacle ITSELF, nothing about the tool. The server + adds how far the fitted tool hangs below the toolhead (the longest of the last tool-setter + measurement, `probe_effective_length` and `longest_bit_length_mm` — a measurement only ever + lengthens the requirement) plus a 5 mm margin. With the touch probe fitted, a 250 mm-high + obstacle still demands 328; with a 2 mm engraving bit it demands 257, and that is where the + machine gets its working room back. If NOTHING is known about the tool, a physically stated + obstacle is impassable rather than passable — state a tool length. Legacy `clearance_z` + records are toolhead heights with a tool already baked in and are enforced exactly as before; + `get_stored_state.landmarkClearances` lists which ones still want re-stating. A hop passes + because it is at or above the requirement (equal passes), never because it is exempt; an + in-procedure hop below it is checked like any low segment; marches are exempt because they + stop on contact. A program's `keep_out` is a + VOLUME: nothing enters, not even a descent column. Never delete or shrink a landmark to make + a plan pass. Measuring INSIDE an unmeasured region is allowed and is how a keep-out is + retired: one sensor-gated march, then `set_landmark` with the measured clearance. +5. **Contact sensors are crash sensors.** While MCP motion is in flight, a trigger on a probe + channel that no procedure declared as expected trips a CRASH alarm: job stopped, connection + closed, motion latched until the operator clears it (Workspace → Connection → Clear alarm, or + `clear_overtravel_alarm` on their words — never yours). The overtravel switch latches the same + way, but ONLY while a procedure or MCP motion is in progress; pressed by hand with the + machine idle it just flashes the pill. Do not disconnect the probe feed while anything might + move. +6. **Chat is not a motion gate — the staged job is.** Every motion tool stages a job and needs + the operator's click: `traverse_xy`, `move_z`, `home`, `goto_tool_change_position`, + `submit_gcode_job`, and every `probe_*` / `run_tool_setter` / `probe_program`. After + staging, call `start_gcode_job {job_id, wait_for_approval_ms: 110000}` (a keep-alive, not a + review budget — it does not scale with job size); `approved: false, timed_out: true` means + call again, never restage. The operator never relays a code through chat. **Deliver the + confirm URL as the LAST LINE of your message, alone, plain — + no tool call after it in the same turn** (the desktop client has hidden it otherwise), with + one sentence above it saying what they are approving. When the operator says "don't bother + me with confirmations": one click per whole procedure IS the minimum — offer the one-approval + program form, do not skip the page, do not lecture. +7. **Use tools for their purpose, through the MCP surface only.** `move_and_capture` is a + vision reposition (≤ 100 mm, a safety cap the assistant never raises, pacing-guarded), not + transport. Transport is `traverse_xy`. Z is `move_z` with `coordinate_system: "machine"`. + Programs someone generated (Luban, CAM) are exactly what `submit_gcode_job` is for — law 7 + forbids file jobs as TRANSPORT, not file jobs. A script looping motion calls is an + unsupervised procedure without a confirm page. Never touch the backend, configstore, or + machine directly while the app runs. +8. **An abort retreats STRAIGHT UP to the traverse height — never to a "start height", never + down.** This is what the server does on every procedure abort (`abortRaiseToTop`): no motion + if the overtravel trip is closing the connection; HOLD if the probe still reads contact (the + operator frees it); nothing sent if the head is already at the top; otherwise one Z-only + move to `mcpSafeTraverseZ`. It is also what YOU do when recovering by hand: after any abort, + refusal or doubt, the first motion is `move_z` to the traverse height, then re-prove position + (`get_position`), then plan again. Never "return to where the procedure started" — before + the travel, the start height is BELOW the head (appendix A, 2026-09-16). A COMPLETED + `run_tool_setter` ends the same way (issue #91): raised straight up to the traverse height, + `result.finalZ` says where the head is — except `stay_at_trigger`, which holds the tip in + contact for the touchscreen wizard and retreats nowhere. + +## 2. Coordinate doctrine + +**Two frames exist on the controller.** `G53` selects the MACHINE frame (home = X−19 Y342 +Z328); `G54`–`G59` select numbered WORK workspaces whose origin the operator sets. The +heartbeat reports the *currently selected* workspace. `G90`/`G91` is **distance mode**, not a +frame: a bare `G90 / G0 Z0` runs in whatever workspace is selected. It is undeclared, and +undeclared is refused. + +**Agents plan, stage, record and quote in MACHINE coordinates.** Say "machine" every time. +Landmarks, tool-setter config, probe results and the geometry store are all machine frame. + +**Every staged job declares its frame — the handshake.** +- **Work-frame job — a Luban/slicer export or the operator's scripted file (the common case).** + Luban exports contain neither `G53` nor `G54`: pass `frame: "work"` to `submit_gcode_job` and + hand the bytes through **unchanged**. You never add `G53` or `G54` to a file you did not + write; you never convert its Z by hand. The MCP resolves the extents through the live origin + and the confirm page shows `Frame: WORK (declared by argument)` plus the **machine-resolved Z + extents** — read both to the operator. `frame: "work"` resolves against the offset on the + heartbeat, i.e. the workspace currently selected on the controller. +- **Machine-frame job.** `G53` must appear literally on its own line before the first move + (the controller needs it; `frame: "machine"` without it is refused). The tools emit `G90` / + `G53;` / moves / `G54;` — the trailing `G54;` reselects Luban's workspace. +- Neither → refused at staging with the rule quoted back. +- Warned, not refused: `G92`, relative moves, Z outside 0…328 in either frame, a work-frame + absolute `Z0`, inline `G53 G0 …` (the firmware ignores a one-shot G53). + +**The work origin belongs to the operator, Luban and the firmware — not to you.** It persists +across homing, **dies on a machine reboot**, and moves when the operator re-zeros or changes +tools. Read it fresh from `get_position.originOffset`; never assume it; the ONE sanctioned write +is `apply_tool_length_offset` (§4). + +**Gantry top is machine Z328.** Work Z0 is wherever the operator put it — on this rig it has +been the stock top and it has been Z328. + +**Any coordinate more than 50 mm outside machine bounds is a BUG, never a position.** Bounds: +X −19…339, Y 0…342, Z 0…328. The server ignores such a beat (§3); you never "recover" from it +with a move, subtract an offset to make it fit, or reinterpret its frame. Plan stations near an +edge (Y340 is 2 mm from the limit) with the margin said aloud. + +**Numbers carry their qualifiers or they are not numbers.** Every height states: frame +(machine), **toolhead Z vs physical surface** (surface = contact Z − probe or tool length), the +tool fitted, the B angle for anything on the rotary, and the date. **Probe length**: an operator +naming a length in chat tells you WHICH probe is fitted, not its calibration — read +`get_stored_state → geometry.probe.effectiveLength`. It is normally set — plan on the stored +value and do not budget an approval for measuring it. Only after you have READ an empty store do +you add one measurement (`run_tool_setter accept_probe_contact`, then `set_probe_geometry`, +§8) and announce it; if store and operator disagree by more than 0.3 mm, ask before converting +anything. The same subtraction gives a cutting tool's surface height: contact Z − fitted tool +length, in machine Z. Figures remembered from text (71.1, 71.2, 71.3) are historical. + +## 3. Position of record — what `get_position` means + +The MCP keeps ONE judged machine position. Read it; never compute your own from a beat. + +| `reliability` | Meaning | Motion and staging | +|---|---|---| +| `verified` | A controller echo or settled heartbeat matched a commanded target | allowed | +| `heartbeat` | Latest beat coherent, offset reported by the controller | allowed | +| `cached-offset` | Beat carried a missing/zero offset; the last complete offset was reused | allowed; re-read once before a position CHECK | +| `awaiting-resync` | The beat was REJECTED (out of bounds, frame-flip signature, or no offset yet) and the record is held at the last accepted position with its age | **refused** by every motion tool | +| `heartbeat` + `frame: machine-frame` | Three consecutive beats read as a legal MACHINE position while the work reading was impossible: the controller is stuck in the machine workspace. The raw fields ARE the position | allowed — but the work coordinates and the offset are not to be trusted until `restore_work_frame` | +| `stale` | No report for > 10 s (period 2 s) — the connection has likely dropped unnoticed | **refused** — reconnect and re-verify | + +**Nothing you do performs the resync, with one exception.** The server clears +`awaiting-resync` when a coherent beat arrives (normally the next one, 2 s). Homing does not +clear it, reconnecting does not clear it, re-reading only lets you see that it cleared. Re-read +`get_position` once after ~3 s. + +The exception is the one that cost a whole session on 2026-09-19: if the controller was left in +the MACHINE workspace — a job declared `G53` and never selected a work workspace again — then +every beat carries machine coordinates with the work-origin offset still populated, `raw − +offset` is impossible, and no amount of waiting fixes it. The server recognises that after +three such beats and says so in `reasons`, reporting `frame: machine-frame` and using the raw +fields as the machine position. **The remedy is `restore_work_frame`**: `G90` and `G54`, no +axis word, permitted precisely because the position is incoherent. A re-home is NOT the remedy, +though it happens to work — it emits a `G54` on the way. + +**Frame hygiene stops it happening.** Every machine-frame job hands the frame back: `G53` on its +own line before the moves, `G54` on its own line after the last one. `traverse_xy` and `move_z` +already emit exactly that, which is the real reason to use them instead of writing the file +yourself; a hand-authored transit that is pure transport is refused and told so. + +Still rejected after ~3 re-reads (~10 s) and not a frame problem: stop polling, call +`query_firmware_position` (proves the controller is alive — it reports WORK coordinates, not an +independent machine frame) and `get_mcp_diagnostics → machinePosition` (rejected-beat counters +by reason), and tell the operator — that is a connection or controller fault, not a wait. `frame: undetermined` means +the judgement rests on no clean reading: treat it as `awaiting-resync`. During a direct move, +beats sampled inside the `G53…G54` window are rejected by design and the record holds the +start position — expect it, do not act on it. + +## 4. Sanctioned exceptions (and their exact limits) + +- **Surface-scan hop envelope** (`probe_surface_path` / `probe_surface_grid` only, between + consecutive stations): retract to **LAST CONTACT + `z_safe_delta_mm`** (cap 20, min 3) and hop + at most `max_hop_mm` (cap 60). Lowering either is always allowed; raising is refused. `hop_mode` + `guarded` (default) hops at travel feed in ≤ 10 mm sensor-checked segments and treats contact + as a COLLISION; `stepped` is a touch-probing traverse that lifts on contact. Choose by the + height change between consecutive stations, not by the surface's name: spacing × steepest + credible slope ≪ `z_safe_delta_mm` → `guarded`; a station may sit more than `z_safe_delta_mm` + above or below its neighbour (steps, pockets, edges, unknown stock) → `stepped`. +- **`apply_tool_length_offset`** — the one sanctioned work-origin write: a single `G92` shifting + work Z by (new − old) trigger height, what the touchscreen wizard does after its two operator + confirmations. Requires a reliable position and a measurement pair from this connection. +- **`operator_confirmed_clearance`** — skips the homed-first / traverse-floor guard on a direct + move. Only on the operator's explicit words, for the corridor they named, in an emergency. + +## 5. Vocabulary (operator-defined) + +- **Home / homing** = machine home, `G53;G28;G54` like Luban's button — ALWAYS. Also homes B. + It clears the NOT-HOMED state; it is not a remedy for `awaiting-resync` or `stale`. +- **Goto work origin** = XY to work (0, 0) at the current Z. Never called "home". +- **Motion floor** = `mcpMotionFloorZ` = machine Z320: the lowest Z any XY move may happen at. +- **Park height** (a.k.a. traverse height) = `mcpSafeTraverseZ` = machine Z328: where procedures + hop, retreat on abort, and end. `get_stored_state.limits` reports both. +- **Toolhead Z** = the Z the heartbeat reports for the head; **physical / surface height** = + toolhead Z at contact minus the probe (or tool) length. +- **`bit_length_mm`** (tool setter) = the fitted tool's PROTRUSION from the collet in mm — a + length, never a diameter. +- **Camera pose for the board** = pre-home park (machine X0 Y0), not machine home. + +## 6. Recording rules + +Record in machine coordinates with the §2 qualifiers via `set_landmark`, `set_probe_geometry`, +`set_tool_setter_config`, `set_camera_calibration` — never by hand into the configstore, never +as constants in a program. A camera calibration is valid at its machine Y AND Z AND depth plane +only. Never hand-seed tool-setter measurement history. Historical position notes from a closed +session are never live position: home first. + +## 7. Running a program someone else generated (Luban, Fusion, hand-written) + +This is what the machine is for, and it is one approval: + +1. Preflight, asked as ONE batch only where the prompt leaves it open: same tool as when the + work origin was set (a swap moves work Z — see `tool-change`)? clamps clear of the XY + extents? deepest Z vs stock thickness? door shut, extraction on? +2. `validate_gcode {gcode}` — read the warnings. `M3 Sxxxx … M5` in a cutting file is normal: + the file owns its spindle (the `M3` refusal belongs to `run_probing_gcode` only). A + spindle-on Z below 0, an unmatched `M3`, or an out-of-travel Z is a warning to put in front + of the operator, not a reason to edit the file. +3. `submit_gcode_job {gcode, name, frame: "work"}` for a Luban/slicer export (§2); the file is + passed through unchanged. +4. Read the operator the confirm page's **Frame** row and **machine-resolved Z extents**. +5. `start_gcode_job {job_id, wait_for_approval_ms: 110000}`; the door interlock applies to file + jobs — the machine pauses if the door opens and resumes from the machine; the job's + `ending` records it. +6. Long-poll `get_gcode_job_status {job_id, wait_ms, since_event}`; `ending.kind` says why it + ended (`completed`, `stopped-by-agent`, `machine-stopped`, `crash-alarm`, …). +7. `stop_gcode_job` on a file job is a firmware stop: motion and spindle stop, nothing retracts, + the cut is not resumable — re-run from the top with the operator.

The plan tags `[APPROVAL]` + on the staging tool and stops, so nothing in it reaches the confirm click it claims. This is + the single cause of Haiku's flat score and the new failures on evals 6 and 7. Law 6 and §7 + describe stage-then-start as two sentences; a weaker model reads the staging call as the whole + gate. → Make the pair indivisible: every canonical call in §8 shows the staging call and its + `start_gcode_job` on the next line, and §0 gets "a staged job you never start is a plan that + never runs — write both calls or neither". +2. **Opus adds a conditional `run_tool_setter` approval on every unknown-Z eval (1, 6, 7)** and a + conditional pre-raise `move_z` on eval 3, and asks 5–7 item batches where Sonnet asks 1–4 for + the same lawful outcome. Two causes. (a) Dry-run artefact: with no `get_stored_state` to read, + Opus assumes the probe length is unstored, so the "unset store = one extra approval" rule + fires. (b) The rule itself invites it: "if unset, measure it" reads as a default branch to + plan for. → State the store is normally populated and a measurement is planned ONLY after + reading an empty store, never pre-emptively; and give the eval harness a stored-state + snapshot so plans stop budgeting for an approval the machine would not ask for. +3. **The `confirm_token` aside in law 6 is a standing hedge.** It cost Sonnet an assertion in + iteration 1 and Opus one in iteration 2 (eval 1): agents document a chat-relayed-code + fallback the operator does not use. → Remove it from law 6; leave it to TOOLS.md. +4. **Two tools still have no canonical call anywhere** and every model guessed them: + `apply_tool_length_offset` (all three on eval 4, including the 12/12 Opus run) and + `set_probe_geometry` (Opus on evals 1 and 6, `{"probe":{"effective_length_mm":…}}` invented). + Real shapes: `apply_tool_length_offset {old_trigger_z?, new_trigger_z?, reason}` (defaults + to the last measurement pair) and `set_probe_geometry {probe_effective_length?, probe_tip_diameter?, + rotary_axis_x?, rotary_axis_z_physical?, reason}`. → Add both to §8; §8 also shows only + `surface_path`, never `surface_grid` (flagged by three critiques on eval 6). +5. **Haiku asks a question and then stages without waiting for the answer** (eval 1: 61 vs 60 + stations; eval 4: the batch omits a value step 1 depends on). No assertion catches it. → New + assertion: a `[WAIT]` must precede the first tool call that consumes a question's answer. +6. **Physical-height derivation is inconsistent on non-probe evals.** Sonnet reasons in work-frame + terms on eval 3 both iterations; Sonnet and Haiku decline to derive the setter-surface height on + eval 4; Sonnet misjudges the rotary-box crossing on eval 2 by checking the endpoint, not the + segment. → Vocabulary: "surface = contact Z − fitted tool length, in machine Z" applies to + cutting tools too; §0 item 4: test the SEGMENT against each landmark box, not the destination. +7. **Haiku's eval-6 grid runs to Y290, inside the chuck jaws' ~Y269 reach, with no keep-out and + no question**; Opus and Sonnet both handled it.

It passes, or it does not: + +| State | What it means | What to do | +|---|---|---| +| verified | The model predicts a known target to within a few pixels, on this connection | use it | +| unverified after a reconnect | The machine has power-cycled since the solve | `verify_camera_model` | +| unverified after a residual | The camera has most likely moved | `camera_bootstrap` | +| a different camera or resolution | It is a different camera | `camera_bootstrap` | +| no model | Nothing has ever been solved here | `camera_bootstrap` | + +Until a model is verified, **nothing converts a pixel into a machine coordinate or a machine +coordinate into a pose** — the tools refuse, and so should you. Plain captures are always +allowed: a frame FINDS things, it clears nothing (law 3). + +### `camera_bootstrap`: solving it from nothing + +Two staged procedures, one approval each. + +1. **`stage: "search"`** — a grid at the park height across the X band the camera could be + looking from, bracketing the tool setter. Which frames contain that unmistakable gold disc, + against the toolhead XY of those frames, gives the camera's offset **including its sign** + while assuming nothing at all. This is the only step that means anything without a + calibration, which is why it is first. +2. **`stage: "poses"`** — the poses that coarse offset implies, each sweeping Z from the park + height to the motion floor with XY stationary, capturing at every stop. Targets at different + heights over that baseline are what make perspective observable. + +Then `scripts/camera_bootstrap.py ` (hand-mark pixels with `--marks` when detection +fails), `set_camera_model`, and `verify_camera_model` against a pose that was **not** in the +fit. A model that has only agreed with its own fit has demonstrated nothing. + +### Choosing a viewing pose + +**`plan_view_pose {target: {x, y, z}}`.** It returns the toolhead XY, the standoff and the +field of view, from the measured model. Then ONE `traverse_xy` (one approval); +`move_and_capture` is for ≤ 100 mm nudges once the feature is in frame. + +Never compute a pose yourself, and never carry one in your head between sessions. An earlier +version of this file stated the offset as fact — "the camera looks −X, seeing roughly 90–150 mm +to the toolhead's −X side" — and on 2026-09-19 an agent followed it, went to toolhead X 290 for +a feature at X≈170, moved +30 mm to check, watched the workpiece slide further out of frame, +and was corrected by the operator to "260 is about the max". Three operator approvals to +establish a sign that one measurement settles. + +The sanity check on a solved model is still evidence: a commanded +X moves the *camera* over +the scene; a commanded +Y moves the *scene* under the camera (platform axis). If a verified +model disagrees with what you see, the camera has been knocked — re-verify, do not re-derive by +hand. + +## Survey first, single poses second (`survey_bed`) + +A serpentine grid, one settled frame per waypoint, saved to disk with a machine-position index. +**Reach for this before a chain of single poses.** The 2026-09-19 session spent forty minutes +and five approvals on single poses, then found what it was looking for in the first grid it +ran. + +- `overlap_fraction` (with a verified model) derives the pitch from the real field of view on + `plane_z`. "Seamless" is a relationship between pitch and field of view; a picked `pitch_mm` + is not one. +- `z_levels` runs the whole grid at several heights under ONE approval, each entered with XY + stationary. +- With a verified model each pass is composed into `mosaic_z.jpg`, indexed in machine + coordinates. Read a feature's position off the mosaic through the index's affine — that is a + lookup, not an inference from one frame and a remembered scale. +- The seams double as the drift check: overlapping frames that disagree mean the camera moved, + and the survey marks the model unverified rather than handing you a skewed mosaic. + +Cover the full reachable envelope — on this rig the far-X column is the only view of the bed +centre-right. Landmarks near each position are the identities the operator already stated. + +## Measuring: the pipeline + +`scripts/board_metrology.py` implements single-frame metric rectification end to end. Read +it before writing your own. + +```bash +python3 scripts/board_metrology.py frame.jpg \ + --quad 421,114 530,133 508,193 409,174 \ + --patch 360,180,560,340 --grid-cm 1.0 +``` + +1. **Colour-mask the board** so line detection never sees metalwork. +2. **Flat-field** (divide by a heavy Gaussian) before Canny — raw edges find shading and + wood grain, not grid lines. +3. **`HoughLinesP`**, split segments into the two angular families. +4. **Vanishing point per family** — SVD null-space of stacked homogeneous line coords. +5. **Affine-rectify** from the line at infinity through both VPs. +6. **Recover the final scale** by asserting a known-rectangular object really is rectangular. + +### Two independent routes, or you have nothing + +The anisotropy from step 6 must agree with the grid pitch from a Radon projection of the +rectified board. In the validating session both routes gave 1.71 — that agreement is the +*only* reason the number was trustworthy. Disagreement by ~2× means a peak-finder locked +onto a harmonic; other disagreement means an under-constrained vanishing point (usually the +family with fewer lines) — re-shoot with more bare board in frame rather than proceeding. + +### The field-of-view sanity check is mandatory + +Convert your scale back to px/cm, multiply out to the frame width, compare with the known +bed size. This check once caught a 1.25× pitch error that both other validations passed. + +## The four things that make a confident number wrong + +**Foreshortening.** One px/mm figure is valid along one direction only. An uncorrected pass +read a block 60 × 35 mm; rectified it was 58 × 45 — the error concentrated in one axis. + +**Top-face magnification.** An elevated face images larger by `D/(D−h)` (D ≈ camera +standoff; at D≈290 mm a 40 mm block reads 16 % oversize). **Measure the base contact line**, +never the top face; if you must use the top face, ask for the thickness with calipers. + +**Parallax.** At tilt θ, a point *h* above the board images `h·tan θ` from the point beneath +it — 0.70 mm per mm at 36°. This is why open-loop moves cannot be verified from high Z. + +**Lens distortion.** Cheap webcams barrel-distort. If you can get a checkerboard on the +bed, do intrinsic calibration and skip the single-frame cleverness. + +## Positioning: servo, do not compute-and-jump + +Never compute a machine coordinate from one frame and drive to it. With the MCP: + +1. Establish state: `get_connection_status` → `get_position` (warnings empty?) → if in any + doubt, `query_firmware_position`. +2. If not homed, `home` — after warning the operator about the rotary, and knowing that + `move_and_capture`/`visual_servo` refuse un-homed motion unless the operator has + explicitly confirmed Z and path clearance (`operator_confirmed_clearance`, which you + pass ONLY on the operator's word, never on your own judgment). +3. Derive the 2×2 matrix at the working Y and Z: command 2–3 known small XY offsets with + `move_and_capture`, measure the feature's pixel displacement with `track_feature` + (never by eye - hand-estimated pixels caused a ~50% calibration error live; on + repetitive grids the second_peak_gap is a SOFT signal, ~0.17-0.25 even for correct + matches, so verify low-gap matches against the Jacobian prediction), fit the forward Jacobian J + (pixel shift per mm), and store M = +J⁻¹ with `set_camera_calibration` (residuals in + `notes`). **Verify the sign before storing**: the tool computes error = target − feature + (check `pixel_error` in a real response against your own numbers), and J·(M·e) must + reproduce +e — a flipped M drives every "correction" away from the target, and it looks + plausible right up until the error grows. The tool warns when consecutive steps fail to + shrink the error; treat that warning as "stop and re-derive", never "push through". +3b. **Calibrations are depth-plane-specific.** The matrix is only valid for features on + the same physical surface it was derived from: applying a bracket-screw calibration to + a feature on the board (different height under a close, tilted camera) predicted ~4× + wrong — real parallax, not a bug. Derive on the surface you will servo on, record the + surface in `notes`, and before trusting any tracked shift, sanity-check it against the + Jacobian prediction (J·Δmachine ≈ Δpixel); a sharp divergence means wrong plane, wrong + match, or both - visual_servo also performs this cross-check automatically and warns + on divergence; tag calibrations with their `surface` so the warning can name it. +4. Iterate `visual_servo` — each call is one clamped step and returns the frame; two or + three passes converge. It auto-selects the nearest-Y calibration and warns when a step + moves Y (self-invalidating) — re-derive or re-select when it does. + +This loop is immune to lens distortion, unknown camera mounting, and an imperfect +homography, because it only ever measures a *difference* near the target. + +Z positioning is not part of the servo: raise or lower Z via `move_z` with +`coordinate_system: "machine"` — one operator-confirmed step per target, never a Z word in a +hand-written file job. Refuse to servo from a height where parallax exceeds +the tolerance you are claiming. + +## Reading a toolhead-camera frame (hardware-learned, the hard way) + +Two live-session failures came from misreading frames, not from geometry. Both are avoidable: + +**Identify by evidence, not by remembered composition.** Never assert "no board in view" +because the frame fails to match a reference framing you were *told about* but do not have. +Describe what IS in the frame and test it against context. On this machine the calibration +board is a **yellow-brown surface with a printed black grid and alphanumeric cell labels +(C1, L1, ...)** — a labeled coordinate grid is a calibration board, not a "cutting mat", +however mat-like its colour. If you have no reference image, say so and reason from content. + +**The rig-mounted vs scene heuristic.** Anything whose frame position is **invariant across +machine moves** is mounted to the same assembly as the camera — the endmill, the spindle +housing — not part of the scene. Scene content (board, rail, bed) visibly shifts between +captures. You always have multiple position-stamped frames; cross-reference before guessing. + +**The endmill's visual signature.** For a toolhead-mounted camera the tool sits millimetres +from the lens: it images as an **oversized, extremely defocused shape entering from a frame +edge at a fixed orientation** (here: from the bottom edge ~2/3 along, pointing diagonally +toward top-left, ~20 % of frame height). That blur is diagnostic of near-lens distance — +categorically different from the resolvable distance-blur of the scene. `capture_frame` +reports the operator-configured `expectedToolRegion` box with every frame — check it before +concluding anything about "an unidentified blurry shape". + +**Landmark identity is operator truth, not visual analogy.** A recurring unidentified +object must not be assigned an identity from what it sits near ("beside jaw-shaped blocks, +so chuck-related") — on this machine the gold cylinder at machine Y≈176–340 is the **tool +height checker**, misidentified twice by analogy before the operator corrected it. If the +operator has named a landmark, use that; if not, ask — never assert a guess as resolved +fact. Landmark identities persist in the registry: call `get_stored_state` first in any +session, and record new operator-stated identities with `set_landmark` - captures then +carry `nearbyLandmarks` automatically. + +## Datums: check the landmark is actually in frame + +A stated datum is worthless if it is outside the field of view. Verify visually before +building on it. When the datum fixes only one coordinate, say so and ask for one anchor +frame — do not extrapolate. Recover axis directions from evidence: a commanded +X moves the +*camera* over the scene; a commanded +Y moves the *scene* under the camera (platform axis). +If those look swapped, something is mislabeled — stop. + +## Safety + +- Motion tools enforce: idle machine, toolhead off, homed-first (or explicit operator + clearance), per-call travel bound, build-envelope check. Do not look for ways around + them; they encode operator rules. +- The endmill may always be in the collet — an XY move at low Z can drag it through stock + or clamps. Read Z before moving in XY; when in doubt, raise Z via a confirmed job first. +- Never send a cutting move (spindle on, or Z below stock top) without fresh human + confirmation — the job confirm page is that mechanism; a stale or reused code is not. +- Report every dimension with an uncertainty. A bare figure reads as authority it has not + earned. diff --git a/.claude/skills/cnc-visual-alignment/scripts/board_metrology.py b/.claude/skills/cnc-visual-alignment/scripts/board_metrology.py new file mode 100644 index 0000000000..56747b9217 --- /dev/null +++ b/.claude/skills/cnc-visual-alignment/scripts/board_metrology.py @@ -0,0 +1,344 @@ +#!/usr/bin/env python3 +""" +board_metrology.py — recover metric scale on a gridded CNC wasteboard from ONE +oblique webcam frame, with no calibration target and no known camera pose. + +Validated on a Snapmaker A350 (640x480 USB webcam, hand-drawn 1 cm grid, ~36 deg +camera tilt).

Skip only if the last stored measurement + (`get_tool_setter_config` → `measurements.last`) is from this same tool, + this session, and the operator confirms nothing has moved. A completed run leaves the + head at the traverse height (machine Z328 — `result.finalZ`), never at its start height, + so the park move that follows needs no separate Z raise. +2. **Park** — `goto_tool_change_position`.

Ask them for the new tool's approximate length. +4. **Measure the new tool** — `run_tool_setter` with the new `bit_length_mm`. + The measurement history now holds previous = old tool, last = new tool. +5. **Shift the work origin** — `apply_tool_length_offset {"reason": "..."}` then + `start_gcode_job {job_id, wait_for_approval_ms: 110000}` (defaults to those + two measurements). It stages a single `G92` — nothing moves; the work frame + shifts by `new − old`.

Built and +hardware-verified against a Snapmaker 2.0 A350 (CNC, 200 W toolhead, rotary module, +bracing kit) during 2026-08; this file is the durable record of the design, the machine +facts learned on hardware, and the development workflow — written so a fresh session can +continue the work without re-deriving any of it. + +## Enabling and configuration + +Off by default. The server configstore is `~/.snapmaker-luban.json` (shared with the +official Luban); the Settings → MCP Server pane edits the main keys, `GET/POST /api/mcp` +serves them, and `LUBAN_MCP_PORT` (env) overrides everything for one run. + +| Key | Meaning | +|---|---| +| `mcpEnabled`, `mcpPort` | Start the server on 127.0.0.1:port (default 40889). Legacy: `mcpPort` alone enables when `mcpEnabled` was never written. | +| `mcpAllowLan` | Default off = loopback only. On: bind every interface but accept only clients (and browser origins) on this machine's own IPv4 subnets; confirm-page links use the LAN address. **No authentication exists** — anyone on that subnet can command the machine; the pane warns in red (the OAuth endpoints in `oauth.ts` grant everyone, see Architecture). Env `LUBAN_MCP_ALLOW_LAN` overrides. Applies at the next start. | +| `mcpToolSetterEnabled`, `mcpProbeToolEnabled` | Default on. Off = that sensor's channel is never bound on any transport (overtravel follows the tool setter): no pill, no readings, and procedures needing it refuse with a clear message. Use when the sensor or the USB bridge is not fitted. Env `LUBAN_MCP_TOOLSETTER_ENABLED` / `LUBAN_MCP_PROBE_ENABLED` override. | +| `mcpCameraUrl` | HTTP(S) snapshot URL; takes precedence over ffmpeg. | +| `mcpFfmpegPath`, `mcpCameraDevice`, `mcpCameraLastGood` | ffmpeg capture — DirectShow on Windows (device = friendly name), v4l2 on Linux (device = a `list_cameras` entry, preferably the stable `/dev/v4l/by-id/… (Name)` form; a bare `/dev/videoN` works but renumbers on replug). Device choice is sticky (last-good preferred); a vanished device is an error, never a silent substitution. | +| `mcpCameraStreamEnabled`, `mcpCameraStreamFps`, `mcpCameraStreamMaxClients` | Live MJPEG view of the camera at `/camera` on the MCP port (see "Live camera stream"). Enabled: unset = on once a camera is configured (URL, pinned or last-good device), else the stored switch; env `LUBAN_MCP_CAMERA_STREAM_ENABLED` overrides. Fps 1–15 (default 5), clients 1–16 (default 4). Settings → MCP Server → Camera edits these; the switch applies immediately (off disconnects every viewer), fps/clients at the next loop start. | +| `mcpMaxJogDistance` | Per-call XY travel cap for direct moves, default 100 mm. `goto_work_origin` is exempt (fixed operator-set destination). | +| `mcpToolRegion` | Fractional box where the endmill images (fixed camera-to-spindle geometry); returned with every frame; settable via the `set_tool_region` tool. | +| *(machine, toolheads, modules)* | **Not MCP keys.** `get_machine_profile` / `get_stored_state` read the machine, toolheads and installed add-on modules (bracing kit, quick-swap) from Luban's own **Machine Settings** (`userData/machine.json`, `state.machine`) on every call — change them in the app (it returns to its home page) and the MCP follows. `mcpInstalledModules` is gone (2026-09-05). | +| `mcpMqtt*` | Probe sensor feed (MQTT): `Host`, `Port` (default 8883 = TLS, 1883 = plain), `User`, `Pass`, `ClientId` (default = username + MAC bytes), `FeedToolsetter`, `FeedOvertravel`, `FeedProbe` (Adafruit IO feed key, or a full topic when it contains `/`), `Inverted` (comma-separated channels whose sensor idles HIGH and reads low on contact — the operator's CNC touch probe is normally open, so `"probe"`). Env `LUBAN_MCP_MQTT_HOST/PORT/USER/PASS/CLIENT_ID/FEED_TOOLSETTER/FEED_OVERTRAVEL/FEED_PROBE/INVERTED` override field-by-field. | +| `mcpProbeTransport` | Which probe feed backend: `mqtt` or `gpio`. Unset = auto: `mqtt`, unless only the GPIO side is configured. Env `LUBAN_MCP_PROBE_TRANSPORT` overrides. | +| `mcpGpio*` | Probe sensor feed (direct GPIO via Adafruit Blinka, default over U2IF — a Pi Pico as USB GPIO bridge): `PinToolsetter`, `PinOvertravel`, `PinProbe` (Blinka pin name with optional pull suffix, e.g. `GP6:up`, `GP7:down`, `GP8` = floating), `Inverted` (same semantics as the MQTT field — a pull-up NO switch idles `1`, so its channel goes here), `Python` (interpreter with `adafruit-blinka` installed, e.g. the venv's; default `python3`/`python`), `PollMs` (default 10, clamp 2–1000), `BlinkaEnv` (NAME=VALUE pairs handed to the monitor so Blinka picks the board — default `BLINKA_U2IF=1`; `BLINKA_MCP2221=1`, `BLINKA_FT232H=1`, `BLINKA_FORCEBOARD=…`, or `native` for on-board GPIO).

Last-resort + workaround: launch with `snapmaker-luban --no-sandbox` (also proves the diagnosis). +- **Local dev**: Node 16 + python 3.11 for node-gyp (details under Development workflow), + `npm install`, then `npm run dev` (watch mode) or `npm run build` + `npm run + start-electron` (production build; see the build caveats below). +- **Python venv — GPIO probe transport only**: `python3 -m venv .venv && + .venv/bin/pip install -r src/server/services/mcp/requirements.txt` (Windows: + `.venv\Scripts\pip`), then point `LUBAN_MCP_GPIO_PYTHON` / `mcpGpioPython` at that + interpreter. Nothing else needs Python at runtime. On Linux, if the monitor dies with + an HID open/permission error, grant the user access to the Pico's hidraw device (udev + rule) and re-plug. +- **ffmpeg — camera capture (Windows + Linux)**: install any ffmpeg build (`apt install + ffmpeg` on Ubuntu) and set `mcpFfmpegPath` if not on PATH. Windows captures via + DirectShow (device = friendly name); Linux via v4l2 — devices are enumerated from + `/sys/class/video4linux` (capture nodes only, listed as + `/dev/v4l/by-id/usb-…-video-index0 (Name)` — stable across replugs, unlike + `/dev/videoN`, which renumbers when cameras come and go), and the user must be able to + read `/dev/video*` (usually the `video` group). Pin `mcpCameraDevice` to the by-id + entry from `list_cameras`, never to a bare `/dev/videoN`. macOS has no + ffmpeg input wired up. `mcpCameraUrl` (HTTP snapshot, e.g. Android IP Webcam) remains + platform-independent and takes precedence everywhere. + +## Live camera stream (2026-09-16) + +The MCP http server also serves the camera to a **browser**, so the operator can watch the +job without pasting frames — same port, same LAN gate as `/mcp` and `/confirm` (loopback +only unless `mcpAllowLan`; `stream_url` follows the LAN address exactly like `confirm_url`): + +| Route | What | +|---|---| +| `GET /camera` | Tiny dark page showing the stream plus a live status line. This is the URL handed out as `stream_url`. | +| `GET /camera/stream.mjpeg` | `multipart/x-mixed-replace` MJPEG, capped at `mcpCameraStreamFps`. | +| `GET /camera/snapshot.jpg` | One JPEG through the very same path the tools take (`captureFrame`); headers `X-Frame-Captured-At`, `X-Frame-Source`, `X-Frame-Id`, and `X-Frame-Stale: true` when only an old frame is available. | +| `GET /camera/status.json` | Loop state: running, clients, provider/device, frame age, stale, last error, fan-out stats. | + +On the Ubuntu box: `http://192.168.1.153:40889/camera` (LAN mode on); on the machine itself +`http://127.0.0.1:40889/camera`. With the switch off every `/camera*` route answers **404** +with a one-line pointer to the setting, and the capture loop never starts for streaming. + +**One device, one owner.** A v4l2 / DirectShow camera opens for one process at a time, so +the stream and the tools cannot both open it. `cameraStream.ts` runs ONE long-lived ffmpeg +(`-f mjpeg pipe:1`, or a poller of `mcpCameraUrl`) only while a browser is attached, splits +the pipe into JPEGs (`mjpegFanout.ts` walks the marker segments; a naive `FFD9` search +would end a frame at an EXIF thumbnail) and publishes each into a `FrameHub`. While that +loop runs, `captureFrame()` in `camera.ts` is served FROM the hub through the +`LiveFrameSource` hook — `capture_frame`, `move_and_capture`, `visual_servo`, `survey_bed` +all keep working, position-stamped and cached (`frameId`) exactly as before, with +`camera.source = "stream"` — waiting for a frame no older than one frame interval (so a +post-settle capture never gets a pre-settle frame). When the last viewer leaves the loop +lingers 5 s, then ends ffmpeg and the tools go back to opening the device themselves +(`source = "one-shot"`); a one-shot capture in flight is awaited before the loop opens the +device. The loop is a child process plus a cheap marker walk, so it never blocks the +heartbeat or motion; if ffmpeg dies it is restarted with 1→30 s backoff while viewers +remain, the last frame stays available and `stale` is flagged. Slow viewers skip frames +(socket backpressure), never queue them; the client cap answers 503. Pure parts +(splitter, hub fan-out/backpressure/rate cap/client cap/stale/awaitFrame, backoff, the +enabled default) are unit-tested in `tests/mjpegFanout.test.ts`. + +Not hardware-tested at merge time: the only camera lives on the Ubuntu box; the ffmpeg +command line is the one-shot capture's input arguments plus `-vf fps=N -f mjpeg`. + +## Architecture + +Own `http.Server` bound to loopback by default (`mcpAllowLan` widens it to this machine's own IPv4 +subnets, with the same-subnet check on every request) — NOT a route on Luban's Express app (whose +`/api` carries the renderer session JWT and whose IP whitelist is LAN-wide). The MCP +transport is hand-rolled stateless Streamable HTTP (JSON-RPC over `POST /mcp`): Electron 15 +embeds Node 16 and the official SDK needs ≥ 18. Zero added dependencies anywhere — +`jpeg-js` (tracking) was already in the tree; the lockfile has never changed. + +**OAuth shim, not authentication (2026-09-07).** Claude Code / Claude Desktop run the MCP +authorization flow against an `http` server before their first JSON-RPC call — metadata +discovery, Dynamic Client Registration, authorization code + PKCE, token exchange — and refused +to connect when the steps 404'd ("Dynamic Client Registration rejected (HTTP 404)"). `oauth.ts` +answers every step: `/.well-known/oauth-protected-resource[/mcp]`, +`/.well-known/oauth-authorization-server[/mcp]` (+ `openid-configuration` alias), `POST +/register`, `GET /authorize`, `POST /token`. It grants everyone: `/authorize` redirects straight +back with a code (no login page — the human decision points are the job confirm pages), `/token` +hands out an opaque bearer, and `/mcp` never checks tokens (never 401s, so clients without the +flow — ChatGPT's tunnel-client, curl — and tokens from before a restart keep working). The +trust boundary is unchanged: every route sits behind the same loopback / `mcpAllowLan` subnet +gate in `index.ts`. What the flow buys is attribution — the registered `client_name` labels +`tool …` log lines (`tool probe_point [Claude Code (luban_…)] <- …`) and the `initialize` line. +Redirect URIs must be loopback http(s) or a private-use scheme; an unknown `client_id` (server +restarted, client kept its registration) is still granted if its redirect URI is loopback. Same +fix also made the server's own per-request address check honour `mcpAllowLan` — it hard-coded +loopback, so LAN clients the outer gate admitted still got `403 loopback only` on `/mcp`. + +``` +mcp/ + index.ts start/stop, config resolution, routing (/mcp, /confirm, /camera, oauth), mcpBroadcast + McpServer.ts JSON-RPC transport, per-call logging + mcp:activity broadcast + oauth.ts OAuth 2.1 / DCR shim for clients that insist on it; grants all, labels logs + registry.ts tool registration/dispatch; McpToolError = tool-level failure + jobs.ts JobManager + human confirm pages (/confirm/); job kinds file|direct + validator.ts static gcode inspection (extents, spindle, distance-mode hazards) + the FRAME + handshake (G53/G54 tracking, resolveJobFrame refuses undeclared jobs) + camera.ts capture providers, frame cache (last 12, frameId), sticky device, LiveFrameSource hook + cameraStream.ts live MJPEG view (/camera*): one ffmpeg loop while viewers exist, serves the tools too + mjpegFanout.ts pure: JPEG stream splitter, FrameHub fan-out (backpressure, fps/client caps, stale, awaitFrame) + tracking.ts zero-mean NCC template matching between cached frames + calibration.ts Y/Z-keyed pixel->mm calibration store (userDataDir, persists) + mqtt.ts minimal MQTT 3.1.1 client over net/tls (hand-rolled, no deps) + probeTransport.ts probe channel names + the ProbeTransport contract + probeFeed.ts external probe sensor feed: config resolution (env->config), + last-reading cache per channel, overtravel tripwire latch, + transport selection + the MQTT backend + gpioFeed.ts GPIO backend: Blinka/U2IF python monitor subprocess (embedded + source, JSON lines: ready|reading|hb|fatal), stall watchdog + toolSetter.ts tool height measurement: config, envelope planner, staged runner + probing.ts shared sensor-gated motion engine (moveMachineSettled, senseAfter, guards) + probeTool.ts / probeVector.ts / probeSequence.ts / probeCircle.ts staged probe procedures + surfaceScan.ts pure station planning + flatness statistics (no imports; unit-tested alone) + probeSurface.ts probe_surface_path / probe_surface_grid plan builders + runner + probeOutline.ts probe_stock_outline: top points + side marches -> centre/size/yaw + probeProgram.ts probe_program: many ops, one approval, references between ops + programRefs.ts pure reference resolution ({from, plus, mid, ...}) with operator bounds + probeGcode.ts CAM probing-program parser (G38.x, links, rotations) - pure + inspectionReport.ts Fusion / Renishaw / csv / grbl / json report renderers - pure + envelopeChecks.ts pure keep-out geometry: checkMotion(segments, obstacles) for planners + positionOfRecord.ts pure: frame matching, controller-echo record, offset judgement, + the gcode sequence counter + machinePosition.ts pure: the judged machine position of record + reliability state + landmarks.ts named landmark store (machine boxes, clearances) -> obstacle boxes + diagnostics.ts event-loop / heartbeat / gcode / sensor timing; publishes mcp:position + jobTiming.ts per-kind timing summary from a job's event log + traversePlan.ts pure: traverse_xy planner (law-2 XY transport at the traverse height, landmark-checked) + tests/ `npm run test:mcp` - node:assert tests for the pure modules + tools/ status, machine, gcode, camera, calibration, probe, toolsetter +``` + +External probe sensors (tool height setter, overtravel switch, CNC touch probe) report +over a sensor feed, not the controller.

Change-reporting: silence means unchanged. +- **GPIO** (2026-09-03): sensors wired to pins read through Adafruit Blinka, by default + via U2IF (a Pi Pico as a USB GPIO bridge, `BLINKA_U2IF=1`). Blinka is Python, so the + transport spawns a monitor subprocess (`python -c`, source embedded in `gpioFeed.ts`) + that polls the pins (default 10 ms) and streams JSON lines: `reading` on change plus a + 1 s heartbeat with all values. The heartbeat doubles as a liveness watchdog (silent + ≥5 s ⇒ kill + reconnect) and refreshes reading ages without log/broadcast spam; trip + decisions stay on change events, matching MQTT semantics. Pin config carries the pull + (`GP6:up`); polarity stays in the shared `inverted` mechanism. Latency is poll + USB + round-trip (single-digit ms vs MQTT's measured ~120–150 ms). Verified against a real + PICO_U2IF (board detect, pulls, heartbeats) and a stubbed Blinka (change detection, + fatal paths incl. unknown-pin reporting the board's available pins). + +The feed auto-connects at service start when fully configured. **Tolerance**: if the sensor +bridge is unplugged (Blinka: "BLINKA_U2IF … no compatible device found") the GPIO transport +reports `bridge: not detected`, the service retries with backoff but logs each distinct error +once (attempt logs thin out after the third), `get_probe_feed_status` shows +`unavailable: true`, pills stay yellow, and every sensor-gated procedure refuses via +`assertChannelReady`. Operators who know a sensor is absent switch it off instead +(`mcpToolSetterEnabled` / `mcpProbeToolEnabled`): a disabled channel is unbound everywhere. + +**Overtravel tripwire**: while a sensor-gated procedure is running (the tool setter / +probing runners declare expected contacts for their whole run) or MCP direct motion is in +flight (`procedureArmed()`), a triggered reading on the overtravel channel immediately +stops the running job, force-closes the machine connection, latches an alarm that blocks +every motion tool (`assertNoOvertravel` in `assertSafeToMove`, `home`, `move_z`, +`start_gcode_job`), and reports to the operator. The latch clears only via +`clear_overtravel_alarm` on the operator's explicit word (refused while the feed still +reads triggered) or an application restart. Outside that window — machine idle, operator +pressing the switch by hand — it is logged and broadcast (`overtravel_unarmed`) but does +NOT latch (operator decision 2026-09-04: "we only care about the overtravel alarm latching +during a tool height test, not for general use"). `disconnect_probe_feed` disarms the +tripwire — never disconnect while a probing procedure could run. + +**Sensor pills** (Workspace → Connection, beside the module badges): Probe / Tool Setter / +Setter Overtravel, each yellow (unknown: feed not connected, no reading yet), green (idle) +or red (in contact) — a visual bump-test aid. A red pill with an **ALARM** marker is the +safety LATCH, not the sensor: it survives reconnects and clears only on the operator's +word — the pill's **Clear alarm** button (confirm dialog → `POST /api/mcp/clear-alarm`, +the operator's own click) or the `clear_overtravel_alarm` tool — or a restart; both paths +refuse while the sensor still reads triggered. Hand bump tests with the machine idle no +longer latch (see the tripwire arming rule above) — the pill just goes red while pressed. +Seeded from `GET /api/mcp` (`probeFeed`), driven live by `mcp:activity` (`probe_feed` +readings / connected / disconnected / alarms), reconciled by a 10 s poll. + +UI integration: verbose console toggle (Workspace) mirrors heartbeat position changes, +every MCP-sent gcode line and controller reply (`[mcp:home] > G28` / `< X:-19.00 ...`), +and tool activity — all timestamped. Events: `mcp:activity`, `mcp:gcode` (whitelisted in +`socket-communication.ts`). + +## Motion laws (operator law after the 2026-09-01 probe crash) + +An XY traverse at a fabricated "clearance" height (Z200, derived from assumptions about +the rotary stock's geometry — wrong twice over) destroyed the fitted touch probe. The +step had also been chained onto an approved Z move in one command, executing 117 ms after +it with no decision point, when the operator had authorised "step 1" only. Laws: + +1. **One motion per instruction, no inferred approvals** — never chain motion tool calls + in a single command or turn; each motion gets its own decision point. Enumerated steps + run one at a time. Only an explicit imperative in the operator's latest message + authorizes a motion; a motion mentioned in passing ("before homing", "then we'll…", + a previously approved plan) is context, not a command — announce and wait. +2. **X/Y traverses at or above the motion floor — ALL of them** (operator, 2026-09-02: + "x/y motion over 1mm is never below gantry height"; revised 2026-09-19 to a floor rather + than a single height). Any XY move over 1 mm happens at or above `mcpMotionFloorZ` + (default **320**, with the heartbeat's 0.05 mm float noise tolerated, so 319.95 up) — no + local hops above a measured feature, no other "measured safe" heights. Retreat, traverse, + descend — in that order. Sub-gantry XY is only fine positioning <= 1 mm (touch nudges, + probe march steps). Enforced: direct XY below the floor refused without + `operator_confirmed_clearance`, which is for emergencies on the operator's explicit + words, not a planning device. + + The floor is NOT the park height. `mcpSafeTraverseZ` (328 = home Z) is where procedures + hop between stations, retreat to on an abort, and end; that is unchanged. The floor could + only drop below it once clearances stopped carrying tool length (law 4), because a hop at + the floor is checked against every stored landmark exactly like any low segment — there + is still no exemption for being high. What the floor costs is 8 mm less blind protection + for anything on the bed with no landmark; `mcpMotionFloorZ` reverts it. +3. **No fabricated clearances** — only measured or operator-stated heights count. Visual + inference finds things; it never clears them. +4. **Landmarks are obstacles** — a landmark's clearance refuses XY paths crossing its box + below the toolhead Z it demands. State it with `obstacle_top_z`: the height of the + OBSTACLE ITSELF, to which the fitted tool's protrusion and a 5 mm margin are added when a + path is checked. The tool is the longest candidate known (last tool-setter measurement, + `probe_effective_length`, `longest_bit_length_mm`), so a measurement only ever lengthens + the requirement; with none of them known a physically stated obstacle is impassable, not + passable. Records set with the legacy `clearance_z` are toolhead heights with a tool + already baked in and are enforced exactly as before until re-stated — + `get_stored_state.landmarkClearances` lists which ones those are. +5. **Contact sensors are crash sensors** — a probe/toolsetter trigger during motion that no + procedure declared as expected trips a CRASH alarm (stop + force-close + latch), the + same machinery as overtravel; `clear_overtravel_alarm` (or the Workspace pill's Clear + alarm button) clears either kind on the operator's explicit word. Motion is "in + flight" inside `moveMachineSettled` (every procedure move, since 2026-09-04) and + `move_and_capture`. Feed readings and all gcode traffic are logged server-side. +6. The approved-code page re-shows the exact gcode next to the approval. + **Chat is not a motion gate — the staged job is** (operator, 2026-09-02): deliberate + traverses/descents go through staged jobs so authorization is the operator's click on the + confirm page against the literal gcode, not a model's reading of chat wording. Since + 2026-09-05 (operator request) that click can be **handed straight to a waiting agent**: + `start_gcode_job` called with `wait_for_approval_ms` stays open until the click and starts + the job with no code to relay (times out `approved: false` after ≤ 120 s; call again). The + one-time code path remains, and Settings → MCP Server → Job approval can require it. A "go" in chat only permits + staging. Re-prove position (home) before a traverse when state is in any doubt, + including after any motion that wasn't part of the agreed sequence. +7. **Use tools for their purpose** — `move_and_capture` is a vision reposition, not a + transport primitive (its `reason` is required and shown to the operator); sequences of + motion belong in the staged, operator-approved mechanisms (`survey_bed`, `move_z` + batches, procedures, `submit_gcode_job`). Enforced: rapid sequential direct moves are + warned then refused (pacing guard) — scripting a motion loop around the direct tools is + an unsupervised procedure without a confirm page, which is what the crash was. +8. **The MCP surface is the only interface** — no agent may touch the machine, its + configstore, or the backend APIs directly while the app runs; every guard lives in the + tools, so bypassing them bypasses all of it. +9. **An abort retreats STRAIGHT UP to the traverse height — never to a start height, never + down** (operator, 2026-09-16). Job fd7fa6cb6396: `run_tool_setter` aborted BEFORE its + travel (the pre-fix traverse check read home as 327.999 < 328) and the old "retreat to + start height" then plunged the head 122 mm to Z 205.5 at the home XY, inside the rotary + landmark. Every procedure's abort path now goes through `abortRaiseToTop` (probing.ts): + overtravel trip = no motion; a probe still reading contact = hold for the operator; at + the top already (float tolerance) = nothing sent; otherwise one Z-only G53 move to + `mcpSafeTraverseZ`. The along-axis "back to the start" legs of `probe_point` / + `probe_vector` are skipped when the start is below the head (`mayDescend`). The + decision is pure and unit-tested (`planRaiseToTop`, tests/traversePlan.test.ts). + **A completed `run_tool_setter` ends the same way** (issue #91): its success path is the + same shared `raiseToTop` — a Z-only raise from the trigger to the traverse height, never + back to its start height — so the head is left where the next XY move must start (law 2). + `result.finalZ` reports where it was actually left. `stay_at_trigger` (touchscreen swap + wizard) is the one exception: no retreat at all, the tip is held in contact. + +### Surface scans — the one bounded exception to law 2 (operator-authorised 2026-09-05) + +`probe_surface_path` and `probe_surface_grid` measure a TOP surface with many −Z marches +in one approved circuit. The operator's words: *"with the grid we need the point to point +variation to not risk the probe toolhead so no more than 20mm z safe delta from the top +(within a horizontal change of 60mm)"*. Hence, **inside these two procedures only, between +consecutive stations only**, the probe retracts to `last contact + z_safe_delta_mm` and hops +horizontally at that height instead of at the gantry. Nothing else inherits this. Bounds +(`surfaceScan.ts`, refused at staging — never clamped or split silently): + +- `z_safe_delta_mm` default 20, **hard cap 20** (min 3) — the hop height above the last real + contact (`resolveEnvelope`). +- `max_hop_mm` default 60, **hard cap 60** — every consecutive station pair must be within + it (`assertHopsWithin`); a spacing/pitch that violates it is refused naming the pair. +- `max_drop_mm` default 40, cap 80 — a station's march may search at most this far below the + previous real contact, and never below `floor_z_machine` (default `start_z_machine − + max_drop_mm`, the deepest Z the scan can ever command — on the confirm page). Reaching the + floor without contact records the station `no_contact` and continues; the reference height + stays the last real contact. The FIRST station finding nothing aborts (no measured + reference to base the envelope on). +- `start_z_machine` is REQUIRED — measured or operator-stated, never guessed. The approach to + station 1 is a full law-2 move: raise to the traverse height, hop, guarded 1 mm descent + (`probe_sequence` pattern; contact = CRASH). Completion and abort both raise to the + traverse height. +- Runtime (`probeSurface.ts`): hops go through `moveMachineSettled` with + `clearExpectedContact()` in ≤ 10 mm sensor-checked segments, so a probe touch during a hop + latches CRASH (law 5); only marches run with `setExpectedContact(['probe'])`. The staged + position and every march start are re-checked (one re-read after ~1.2 s). + +**Descents are segmented (operator law, 2026-09-05).** A single long `G1` toward the work +cannot be stopped once sent — a collision would be driven to the end of the move. Every +procedure descent (surface scans and probe_sequence to the guard top, probe_circle to its +probe height, the tool setter's travel to its start height) is therefore issued in +`descendInSegments`: segments of **≤ 5 mm**, and **none of them waits on the heartbeat** +(lenient settle: the controller's ok is the gate; a misframed or missing echo records the +commanded Z as `estimated`). Contact detection during a descent is **asynchronous**: the +probe feed's crash guard latches CRASH the instant an unexpected channel fires while motion +is in flight (job stop + connection close), and every segment re-checks the latch before it +is sent, so a hit ends the descent within one segment with no serial sensor wait between +segments. A manoeuvre that needs a synchronous verdict passes `serialCheck` (a `senseAfter` +window after each segment). The tool setter's travel clears its expected-contact set for +the descent, so a setter hit above the start height is a collision, not a measurement. The +1 mm guarded final approach and the coarse/fine ladders (which do sense serially, because +contact there is the measurement) are unchanged. Upward moves stay single. + +**Coarse press and the slow zone (operator, 2026-09-05, job d8f6ec1b5c11).** A coarse step is +executed whole by the controller before the runner sees the probe, so wherever the surface +is found by a coarse step the probe is pressed past contact by up to a FULL coarse step +(0.4 mm at station 1 with 2 mm steps; worst case the whole step). `coarse_step_mm` is +therefore also the worst-case press. From station 2 the runner knows the expected contact +(the previous station's Z), so — like `run_tool_setter`'s `slow_zone_mm` — coarse steps now +stop `slow_zone_mm` (default 1, min 0.3) above it and fine steps take over, down to +`slow_zone + 2 × coarse` below it (coarse resumes lower, so a pocket edge costs seconds). +Press in the zone = one fine step. Station 1 has no neighbour: coarse is capped at 1 mm +unless `expected_z_machine` (a MEASURED neighbouring contact, law 3) is given. The confirm +page prints the zone; each station result carries `approach` (`slow-zone` | +`coarse-contact`) and `worstPressMm`. Bonus: no coarse contact means no release-and-return +ladder, ~5–8 s saved per station. **`coarse_step_mm` is capped at 1 mm everywhere in +surface scans** (operator, job cdbc29371b97: "we never wanted 2mm"; range 0.5–1, default 1). +Verified on the rerun (cdbc29371b97, 8/8, same numbers as d8f6): every station +`slow-zone`, `worstPressMm 0.1`, 408 s vs 492 s. + +**Where the time goes (measured 2026-09-05, on-box analysis of the four-face survey).** Every +command batch costs ~270 ms over its motion time on the WiFi channel (four HTTP lines per +batch); motion time is distance / feed, so short steps are dominated by that overhead. + +| Step | Feed | Motion | Measured per command | +|---|---|---|---| +| Coarse 1 mm | F100 | 600 ms | ~874 ms | +| Fine 0.1 mm | F60 | 100 ms | ~365 ms | +| Backoff 0.3 mm | F60 | 300 ms | ~574 ms | +| Retract 20 mm | F600 | 2000 ms | ~2280 ms | +| Descent segment 5 mm | F600 | 500 ms | ~834 ms | +| Raise 120 mm | F600 | 12 s | ~12.4 s | + +An 11-station path at 402 s split as: 179 s coarse steps, 51 s fine, 35 s confirm, 26 s +retracts, 20 s hops, 18 s station-1 guard band, 17 s backoffs, 14 s initial descent, 16 s +traverse + final raise, 25 s of sensor windows; ~31.5 s per station of which 19 of the 30 +commands are the coarse walk back down from the 20 mm hop height. Levers, no code needed: +`z_safe_delta_mm` 20 → 5 (~145 s per scan; the hop guard still catches a surface rising > 5 mm), +`confirm_passes` 2 (~19 s), `sensor_delay_ms` 30 (~8 s); coarse feed F100 → F300 (~80 s) is an +operator call on impact speed. Code levers: `get_job_timing` / `result.timing` now compute this +breakdown from any job's events (per kind: count, feeds, distance, controller vs motion vs +overhead, idle, sensor windows; per station; waits). One-line `G53 G1 …` (three lines per +batch, no workspace switch, ~100 s per scan) is NOT used: it is unverified on this firmware and +an unsupported inline G53 would execute in WORK coordinates. Station 1 of a surface scan now searches down to an explicit `floor_z_machine` (job +d7ac9247838e aborted because only start − max_drop was honoured). + +**`probe_program` — one approval for a whole survey (2026-09-06).** An ordered list of +operations, staged once and approved on ONE confirm page that enumerates every op's envelope +and the B rotation schedule, run by one runner that hands the machine from op to op (each ends +raised at the traverse height): `rotate_b` (absolute B on the direct path, refused unless the +toolhead is at/above the safe traverse height, verified by the M114 in the same batch or the +heartbeat's `b`), `surface_path`, `surface_grid` and `sequence` with their standalone +arguments. Numbers an op cannot know at staging are **references** to earlier results — +`{from: "c90.top.z", plus: 7, between: [200, 240]}` (a sequence probe by name, `.z` shorthand +for `contactMachine.z`) or `{from: "ns90.summary.zMean", minus: 7, between: [...]}` — with +operator-approved **bounds required** (law 3): the page shows the bounds and a preview plan at +the mid-point, and the runner refuses the op if the resolved value falls outside them, +stopping the program raised and keeping every earlier result under `result.ops`. `on_fail: +"skip"` records a failure and continues (rotations always stop). Each op result is the +standalone tool's result object. The four-face survey that took 18 approvals is one program: +`rotate_b 90 → sequence (centre) → surface_path N–S (expected from the centre) → surface_path +W–E → sequence (sides) → rotate_b 180 → …`. + +**New stock from the jig alone (mcp/48, 2026-09-06).** What the manual four-face survey did by +hand is now in the program tooling (work plan and hardware test order in +[docs/NEW_STOCK_SURVEY_TODO.md](docs/NEW_STOCK_SURVEY_TODO.md)): + +- **Two-operand references** (`programRefs.ts`): `{mid: [a, b]}` = (a+b)/2 (stock centre from + two side contacts), `{diff: [a, b], scale: 0.5}` = (a−b)·scale (width, half-width), + `{min|max: [...]}`; `plus`/`minus` may be a number or a path, so "axis + half-width" is one + reference: `{diff: ["s0.east.x", "s0.west.x"], scale: 0.5, plus: "axis.z_contact", between: + [210, 235]}`. `.x/.y/.z` on a sequence probe read `contactMachine`. References may sit at + any depth of an op's arguments (`steps[1].z`, `expected_profile.circle.center_x`). Bounds + stay required; the page prints the formula (`describeRef`) and the runner the values. +- **Rotary axis and probe geometry through the MCP surface** (`rotaryGeometry.ts`, tool + `set_probe_geometry` — operator-stated or MEASURED values with a reason, like `set_landmark`; + env overrides `LUBAN_MCP_ROTARY_AXIS_X/_Z`, `LUBAN_MCP_PROBE_LENGTH`, + `LUBAN_MCP_PROBE_TIP_DIAMETER`; read back in `get_stored_state → geometry`): axis X and + PHYSICAL axis Z, probe effective length and tip diameter. Programs read them as the seeded + namespace **`axis`** (`axis.x`, `axis.z_physical`, `axis.z_contact` = axis Z + probe length, + `axis.tip_radius`, `axis.probe_length`). **Never a prerequisite**: only a reference to + `axis.*` needs them (then a missing value is a staging error naming the tool); B0-only, + stationary and off-rotary work needs nothing. **Stock size is not stored anywhere** — it is a + property of the stock, not the jig — so a rotation takes an optional per-program + `swept_radius_mm` for the tip-outside-the-cylinder check. (A first cut put these in the app's + settings pane with a "max stock radius"; the operator rejected it on 2026-09-06 and it is + gone.) Measured values this jig: axis X ≈ 169.7, physical Z ≈ 112.4, probe 71.3, tip ≈ 2.5 — + re-measure after any probe re-fit or rotary move. +- **Keep-out at plan time** (`envelopeChecks.ts`, law 4 in the planners): every `probe_sequence` + hop / descend column / march and every surface-scan station-1 descent, hop (at its lowest + possible height, floor + z_safe_delta) and station column is checked against the obstacle + landmarks (`clearanceZ` set) and the program's transient **`keep_out`** boxes (`[{name, + machine: {x0, y0, x1, y1}, clearance_z}]`, this clamping's chuck jaws / tailstock, shown on + the page, never persisted). Two obstacle semantics: stored landmarks are **crossing** + obstacles — their clearance forbids entering or leaving the box on a low path, exactly what the + direct XY guard enforces, while a hop, column or march wholly inside the box is the approved + procedure (the `rotary-axis` landmark covers the whole stock; probing it is the job — the first + cut treated it as a volume and refused every descent, caught by the on-box agent 2026-09-06); + program `keep_out` boxes are **volumes** nothing enters, not even a column. A hit refuses + staging naming the step, the obstacle and the Z; the check re-runs when references resolve at + run time. `rotate_b` with `swept_radius_mm` additionally refuses if the tip is inside that + cylinder (`insideSweptCylinder`). +- **Discovery**: `summary.highestAt` / `lowestAt` (machine XY) locate a cylinder's crown or a + face's high edge by reference; `surface_path expected_profile: {circle: {center_x, + center_z_contact, radius, tip_radius?}}` models a cylinder along machine Y — each station's + slow zone and max_drop band follow `z(d) = c + √((R+rt)² − d²) − rt`, stations beyond 0.7 R + off the axis are refused (the tip would glance). Unknown height needs no new op: a sequence + whose `descend` is `axis.z_contact + (largest possible radius + 5)` and whose probe travels + that radius + 10 (segmented descent, 1 mm coarse in the last band). +- **`group`**: `{id, kind: "group", for_b: [0, 90, 180, 270], ops: [...]}` expands at staging + into a `rotate_b` per angle followed by the inner ops with the token `${b}` replaced in every + string; inner ids without the token get `_b` and references between them are rewritten + (`programGroups.ts`). Cap 80 ops after expansion. +- **Derived section** on the program result (`stockGeometry.ts`, `result.derived`, labelled + inference not clearance): face heights above the axis per B, opposite-face thickness and + centring offset, centre-to-centre width and PHYSICAL width (minus the tip diameter: external + faces lie one tip radius inside their contacts) and stock centre X per Y, yaw per 100 mm, end + face slope, top-face slopes — the 2026-09-05 report's arithmetic, unit-tested against it. + Relies on probe names `top`, `west*`, `east*`, `end*`; every op result carries its `b`. +- **Event budget**: the plan estimates its events (100 + 120/station + 60/probe + 20/rotation); + staging is refused when the estimate exceeds the job event limit, naming the number to set. + +Still open from the brief: multi-segment paths in one op, live progress on the confirm page. + +**`probe_stock_outline` — top, outline and centre from an estimate (2026-09-06).** The +operator's ask after watching the agent re-probe the centre for every side: one approved +procedure that (1) finds the TOP at a few points around the estimated centre (`top_points`, +default 3 along the longer axis) — the highest contact wins and a sample lower by more than +`hole_tolerance_mm` (default 2) is a hole and ignored, so a first probe landing in a drilled hole +does not define the surface; (2) probes the SIDES with horizontal marches from `overextend_mm` +(default 5) outside the estimate at `top − side_depth_mm` (default 2), `points_per_side` (default +3, midpoint first) over the middle half of each side (corners are where estimates fail), each up +to `side_max_travel_mm` (default 25), a miss recorded as `no_contact`; (3) FITS per-side mean and +slope into centre (machine and work frame), size centre-to-centre and PHYSICAL (MINUS the tip +diameter: on opposite external faces each stylus centre stops one tip radius outside its face — +the on-box agent caught the earlier "+ tip" sign error; the centre is unaffected) and yaw +(`outlineFit.ts`, pure, unit-tested against the agent's block: centre 168.85 / 241.383, physical +44.27 × 69.0). **Why 25 mm:** the agent's first outline marched 11 mm from X132 and found nothing +on the west; the face was at X145.5 — the estimate's centre was 3.85 mm off and its width a few +mm out. A short march silently turns ordinary estimate error into a missed face; a generous one +is still sensor-gated and only costs time. Derive travel as overextend + width uncertainty + +centre uncertainty + margin, never less than 20–25 mm. Also a +`probe_program` op kind `stock_outline`. The motion machinery is shared in `march.ts`: +`marchToContact` (the coarse → release → fine → confirm march every runner used to copy) and +**`steppedTraverse`** — travel close to a surface as a TOUCH-PROBING move: 1 mm steps at F300 +with the probe expected; a contact backs off one step, retreats `hop_lift_mm` (default 2) along +the retreat direction and continues, so the path follows the surface in steps (a gentle slope, +one lift at the wall of a hole, one bump for a projection on a side). Over a top the retreat is ++Z, capped at the traverse height where a plain move finishes (law 2); along a side it is AWAY +from the face, capped at the approved start line where a further contact is a fault. Between +side points the probe backs off the last contact by `side_standoff_mm` (default 3) and skips +along the face at that standoff; the next march starts from the arrival point (a dynamic start +off the previous contact, never a fresh approach from the outside line). Surface scans take the +same idea as `hop_mode: "stepped"` (`hop_lift_mm`) in place of the fixed `z_safe_delta_mm` hop +whose only answer to a contact was to abort; `guarded` stays the default. + +**CAM-generated probing programs — `run_probing_gcode` (mcp/49, 2026-09-07).** Fusion 360, +FreeCAD, any Grbl/Marlin post or a hand-written file supplies the probing toolpath as gcode; the +server PARSES and TRANSLATES it (`probeGcode.ts` pure parser/simulator, `probeCam.ts` +planner/runner) — never sends it raw, because the firmware has no G38 cycle and a raw program +obeys none of the motion laws. `G38.2`/`G38.3` become the shared sensor-gated march toward the +programmed target (the travel limit; retreat to the cycle start; G38.2 without contact aborts +per Grbl unless `on_miss: "continue"`); `G38.4`/`G38.5` become a probe-away (coarse steps until +the probe releases, then on to the target); `G0`/`G1` links follow law 2 (`link_mode: "raise"`: +traverse at the safe height and guarded segmented descent to the programmed Z; `"stepped"`: a +touch-probing traverse at the programmed height that lifts on contact); `G4` dwells; `G90/G91`, +`G53`, `G20/G21` honoured; programmed feeds ignored. Refused at staging with the line number: +`M3/M4` (spindle with the probe fitted), `M0/M1`, `M6`, `G28`, `G92`/`G55-59`, arcs, macro +variables. Coordinates are the CAM's WCS (work frame) unless `frame: "machine"` or `G53`. Probe +metadata in a comment before a cycle — `(PROBE id=3 name=top nominal=10,20,0 normal=0,0,1 +tol=0.1,-0.1)` — supplies nominals, normals and tolerances. The confirm page enumerates every +translated step beside its original line; the keep-out check runs like any procedure. The +**inspection report** (`inspectionReport.ts`, pure) is stored as JSON on the job and rendered by +`report_format` / `get_inspection_report`: `fusion` = Fusion 360 inspection results in the exact +shape Autodesk's own "result generator probing.cps" writes (verified 2026-09-07, see +[docs/FUSION_POST_REVIEW.md](docs/FUSION_POST_REVIEW.md)): `START` / `RESULTSFILE` / `DOCUMENTID` / +`MODELVERSION` / `TIMESTAMP`, per toolpath `TOOLPATHID` / `TOOLPATH` / `G331` (CAD transform) / +`G330` (work plane; the 3+2 station's B goes in its `B` word), per point `G800` (nominal XYZ 4 dp, +normal IJK 6 dp, `O` = inspect surface offset, `U`/`L` tolerances with `L` signed) and `G801` +(measured TIP-CENTRE XYZ, `R` = stylus radius — Fusion subtracts it itself), then `END`; a miss = +nominal only.

Six derived fixtures live in `docs/examples/cam-tests/` (each names its source and +transformation) and the ten-item verification set - six software assertions, four on the machine +with an artefact - is the plan for the first hardware runs. The survey also surfaced two parser +gaps, both fixed: nested parentheses inside a comment (`(MSG, do (this))`) and Grbl `$J=` jog +lines in sender macros (skipped with a warning); and the UGS hole-centre routine's `G53` links +under `G91` are taken as absolute machine coordinates with a warning.

Unit-tested on +a 25 mm boss (surfaces one radius outside each tip centre), an out-of-tolerance case with the radial +error, and a hole with a missed point. + +**Snapmaker firmware facts for the translator (2026-09-07, from Snapmaker/Snapmaker2-Controller and +the wiki's supported-gcode page).** The controller is a customised Marlin 2.0: `G0/G1` (with a `B` +word), `G4`, `G20/G21`, `G28`, `G53`, `G90/G91`, `G92` are supported and verified by Snapmaker; +`M3/M4` are "modified" (P = power). `G38_PROBE_TARGET` and `G38_PROBE_AWAY` are compiled in +(`Marlin/Configuration_adv.h`), so the firmware has a native `G38.2`–`G38.5` — but it probes the +Z-min probe endstop, the 3DP head's proximity sensor path, not the CNC touch probe on the MCP's GPIO. +The MCP therefore keeps translating every cycle into its own sensor-gated march and never sends a +G38 to the controller. Whatever dialect a program arrives in (Fusion post, Grbl sender macro, +LinuxCNC, hand-written), the parser maps it onto the codes the controller actually runs (`G90` / +`G53` / `G1` / `G54` batches and `G0 B` rotations) or refuses it by line. + +**A probing-capable Fusion post: [docs/post/snapmaker-probing.cps](docs/post/snapmaker-probing.cps).** +Snapmaker's own posts are "all rights reserved" with no probing, so this one is written from +scratch (AGPL like the repository) to the review's outline: probing and Inspect Surface operations +only; each cycle becomes a law-2 approach (`G53 G0 Z`, `G0 XY`, `G0 Z`), a `(PROBE …)` +comment with nominal, normal, tolerances, feature, group and role, and one `G38.2` whose target lies +a generous `minOvertravel` (15 mm) past the expected surface; 3+2 via `optimizeMachineAngles2(1)` +(post-transformed XYZ) and a bare `G0 B` after a raise; a `(RESULTS …)` comment per operation; no +M3/M6/G28/G92/arcs; simultaneous multi-axis and PCD cycles refused. Cycle geometry is written from +the Autodesk cycle parameters (`probeClearance`, `probeOvertravel`, `approach1/2`, `width1/2`, +`probeSpacing`, `depth`) and **has not been run in a Fusion installation** — verify each cycle type in +the post editor before trusting it; the rotary axis offset property must match the WCS origin. + +**3+2 stations in a CAM program.** A bare `G0 B` line is a rotation: the translator raises +to the traverse height first (law 2, enumerated on the page) and runs `rotate_b` (absolute, direct +path, verified by M114 / the heartbeat's `b`); `B` with X/Y/Z, incremental `B` and `A`/`C` are +refused. The review found no probing-capable Snapmaker post exists: Snapmaker's 3-axis post is a +2018 Marlin post with no probing, and its "4-axis" post is an unmodified Autodesk Fanuc post with +Renishaw macros (refused line by line here) whose `writeRetract` emits no motion before a `B` +word. The review's patch outline for a `snapmaker-probing.cps` (post-transformed XYZ + bare `B`, +`G38.2` per cycle type with `(PROBE …)` metadata, raise before every rotation, no M3/G28/G92) is in +the same document. + +**Traverse height and landmark clearances (revised 2026-09-14).** Job 34d787bdb2d7 (2026-09-06) lost +its last op because the `rotary-axis` landmark declares clearance 328 (the homing height) while +the traverse height was then 320: a hop at 320 out of the rotary footprint was refused. The fix at +the time exempted segments at or above `mcpSafeTraverseZ` from CROSSING landmarks - which also +let a traverse cross the rotary box, tailstock included, with 8 mm of headroom nobody had +measured. Operator decision: `mcpSafeTraverseZ` now defaults to **328** (= home Z), and the +exemption is REMOVED - a hop at 328 passes every stored clearance on its own merits, a hop below +328 (a surface-scan hop, a stepped link) is checked against crossing landmarks like any low +segment, marches stay exempt (they stop on contact), and a program `keep_out` VOLUME refuses at +any Z below its clearance. In-procedure sub-motions keep their tool-specific envelopes; every +procedure ends raised to 328. `get_stored_state.limits.safeTraverseZMm` reports the live value. + +**A missed march is a measurement, not a fault (2026-09-06, job 5ad5fcce6b3a).** The agent's +six-op centre-finding program aborted on its LAST op because the first south-side march started +beyond a corner of the stock (width and step over-estimated) and found nothing within its +25 mm - five completed ops were thrown away with it. `probe_sequence` steps now take `on_miss`: +`continue` (default) records `{status: "no_contact", limitMachine, maxTravelMm}` for that probe, +retreats, raises and carries on; `abort` keeps the old behaviour. Results carry `status` on every +entry plus `contactCount` / `noContactProbes`; a later reference to a missed probe fails to resolve +and refuses that op (program stops raised, everything else kept). Surface scans already treated a +no-contact station this way. + +**Stopping a procedure (fixed 2026-09-06, job 5ad5fcce6b3a).** `stop_gcode_job` only knew the +firmware's `stop_print`; a procedure is a server-driven loop, so three stop calls answered +`ok: false` while the scan kept stepping. Now `requestProcedureStop()` (probing.ts) records a +request that every motion primitive (`moveMachineSettled`, `senseAfter`, `rotateB`) checks +before sending: the runner throws `ProcedureStopped` at the next step boundary, its normal +abort path raises to the traverse height, and the job ends in state `stopped`. `ProcedureAbort` +now carries `partial` (completed stations / contacts / ops) and the runner wrapper stores it as +`job.result`, so the earlier promise "results are on the job record" is true for every abort, +not only for stops. A program treats a stop as program-wide regardless of `on_fail`. The tool +waits up to `wait_ms` (default 20 s) and returns `{ok: true, stopped | stopping, job}`. + +## Safety model (operator-defined, non-negotiable) + +- **Every staged job declares its coordinate frame, or it is refused** (2026-09-14, after a + work-frame `G0 Z0` transit job reached the confirm page reading "Z 0 .. 0, warnings: none"). + `G53` on its own line before the first move = MACHINE; `G54..G59` in the file, or + `frame: "work"` on `submit_gcode_job` for a Luban/slicer export that selects no workspace = + WORK (the file is never modified); `frame: "machine"` without a literal `G53` is refused, and + so is a job that declares nothing. The confirm page shows **Frame** and the **machine-resolved Z + extents** (work-frame Z through the live origin offset), so the operator validates a Z without + trusting chat. `G92`, mixed frames, out-of-travel Z and a work-frame absolute `Z0` are loud + warnings. Every MCP emitter declares too (`G53;` in every planner preview, an explicit `G54;` + before a work-frame `move_z` / `move_and_capture`). See "Coordinate frames and the position + of record" below. Agent guidance: `.claude/skills/cnc-motion-rules/SKILL.md` (canonical) and + `.claude/skills/README.md`. +- **Compound motion and all cutting goes out as gcode FILES** through the same + `prepare_print`/`start_print` path as Luban's Start button, so the controller job state + machine and the enclosure **door interlock** apply (fork issue #23). The direct + (`execute_code`) path is reserved for single guarded actions. +- **Human confirm page** (`/confirm/`, loopback + Origin-checked): shows validation, + extents, warnings, and for direct moves a banner stating the interlock does NOT apply. + Approval mints a one-time code (15 min TTL). Only the operator's click authorises motion: + a model cannot approve its own job. By default (`mcpApprovalHandoff` = `agent`) an agent + already waiting in `start_gcode_job wait_for_approval_ms` is started by that click and the + page says "handed to the waiting agent" (the code is still printed small as a fallback); + with `code` (or `LUBAN_MCP_APPROVAL_HANDOFF=code`) the code must be relayed by hand as + before. Batch direct jobs: one approval covers an exact target list; each + `start_gcode_job` call executes one step. +- **Z policy**: no Z through XY tools, ever. `move_z` = per-move operator confirmation + showing current Z, target, delta, feed. Every request needs a `reason`. +- **Guards on every direct move**: machine idle, toolhead off (headStatus/headPower), + homed-first (override `operator_confirmed_clearance` only on the operator's explicit + word), travel cap, build-envelope check with overtravel allowance (machine −25..+40 — + X home rests at −19). +- **Verified-settle contract**: motion tools block until the returned position verifiably + matches the move (Z parsed from the executed gcode, ±0.15 mm; XY at target; home must + leave its pre-G28 position at least once). `wait_until_moved: false` opts out and always + returns `position_verified: false` with a poll instruction. `capture: false` = verified + move without a frame. +- The endmill is ALWAYS in the collet; the rotary is fitted and may hold stock. Report + dimensions with uncertainty. See `.claude/skills/cnc-visual-alignment/` for the full + vision methodology. + +## Machine facts (hardware-verified 2026-08-30) + +- Controller has **G53 (machine workspace) and G54+ (numbered workspaces)**; the heartbeat + `pos` is in the *currently selected* workspace. Convention everywhere: + `machine = work − originOffset`. +- **Bed = 320 × 340 × 330 mm (X/Y/Z), with extra travel on BOTH ends of every axis** + (operator, 2026-09-02) — matching the observed extremes below. +- **Machine home = (−19, 342, 328)**; **firmware X limit = 339** (sweep-verified 2026-09-01: + tracks requests exactly through 330, clamps a 340 request at 339 — the tool-change park X); + homing = `G53;G28;G54` exactly like Luban's button + (a bare G28 leaves reporting in an unselected workspace → impossible derived coords like + Y 464/Z 656). Homing takes ~15–20 s and **also homes B — stock on the rotary rotates**. +- **Work origins are operator-set per workspace and persist across homing — but NOT across + machine reboots** (operator, 2026-09-02): a rebooted machine gets a new work origin, so + never assume it carries over between sessions; re-verify `originOffset` after every + (re)connect before trusting work coordinates. +- **The machine interpreter returns to Z top at the job's finish position when a file job + COMPLETES** (operator-clarified 2026-09-02; supersedes the earlier "parks at the work + origin" reading — Z top and this setup's work-origin Z are both 328, which hid the + difference). XY holds; Z does not — that is why `move_z` exists on the direct path. + The job-concept split that matters: machine-interpreter (file) jobs get the door-detector + emergency stop; MCP direct single-command ops do NOT. +- **Heartbeat period is 2 s on WiFi** (`workers/heartBeat.ts` polls `/api/v1/status` every + 2000 ms with a 3 s timeout — not the ~1 s assumed until 2026-09-05), and a beat's position + can be sampled before a synchronous move finished, so a settled-looking heartbeat can + predate the motion (hence the verified-settle contract). `query_firmware_position` (M114) + is the authoritative check. The HTTP channel sends each gcode line as its own request, so + the engine's `G90` / `G53;` / `G1 …` / `G54;` is four requests and a status poll can land + INSIDE the G53 window: that beat reports **machine coordinates in `pos`**, with the offset + either still populated (a "frame flip"; `diagnostics` counts `heartbeat_frame_flip`) or read + as **(0, 0, 0)** (`zeroOffsetBeats`; set aside by `judgeOffsetReport` until a zero offset + persists for 3 beats) or missing (`missingOffsetBeats`; the cached offset is used). +- **Origin-offset transient (2026-09-05, job 44abebd9bab3)**: the SSTP status poll rebuilds + `originOffset` from `offsetX/Y/Z` on every beat, and a beat inside a move's `G53…G54` + window can carry none — `getPositionSnapshot` used to fall through to zero and reframe + machine coordinates as work coordinates ((170, 199, 240) read as (119, 77, −88)), which + aborted a probe_sequence march re-check after every step had verifiably settled. Now a + missing offset reuses the last complete one (`originOffsetSource: cached`, with a + warning). This session's work origin sat at machine (51, 122, 328) — negative offsets in + the heartbeat; `machine = work − originOffset` holds. +- **Position of record (2026-09-05, job 1db4902a4cd6)**: the same afternoon a surface scan + aborted at its station-4 re-check after three clean stations, on two bad beats in a row: + one lagging (still the previous hop segment's position) and one frame-flipped + (170, 207.571, 227.7 in `pos`, offset present → "machine (221, 329.6, 555.7)"), while the + controller had echoed both hop segments at their targets. Rules now (`positionOfRecord.ts`, + `probing.ts`): + - every verified arrival (controller echo, or settled heartbeat) is the engine's **position + of record**; any other gcode sent to the machine voids it; + - a status report is judged in **either frame** — `pos − offset` (normal) or raw `pos` + (G53-window beat) — for echoes, settle waits, `move_z` waits and re-checks; + - a re-check passes on a matching report in either frame, or on the record while the + latest report still predates it; it aborts only when **two distinct reports agree** the + machine is elsewhere (real drift), or nothing matched within 4.5 s; + - **operator rule**: a move of ≤ 1 mm that the controller accepted with no contradicting + echo is taken as arrived after a 400 ms grace if the heartbeat has not caught up + (`position-estimated` event) — inching is never paced by the 2 s poll. Larger moves + still wait for verification. +- Camera is **toolhead-mounted** (rides X/Z; the platform moves under it in Y): pixel→mm + calibration is keyed by machine Y AND Z. The board-viewing anchor pose is the pre-home + park (machine X0/Y0), not machine home. The **gold cylinder at machine Y≈176–340 is the + TOOL HEIGHT CHECKER** (operator-confirmed; was misidentified twice). +- **Tool setter: centre at machine (X79, Y293), top-left of bed. MEASURED trigger Z 175.500 + with the 75 mm reference endmill (three confirm passes agreed, spread 0)** — so the setter + SURFACE is machine Z 100.5, and expected trigger Z for a bit of length L is + `175.5 + (L − 75)`. Config + measurement history live in `mcpToolSetter`. +- **Touch probe (measured 2026-09-01): effective length 71.1 mm** (trigger on the setter at + machine Z 171.6 ⇒ any surface = probe contact toolhead Z − 71.1). The probe's AXIAL + spring is stiffer than the setter's switch, so on the setter the SETTER fires first — + measuring the probe there is safe with `accept_probe_contact: true` (either channel + confirms). Probe feed latency, hardware-measured: **~120–150 ms** sensor→feed on a local + bump test (trigger message 452 ms after move issue incl. ~330 ms motion) — the 200 ms + contact windows are correctly sized. +- **Camera offset**: the toolhead camera looks roughly **90–150 mm in −X** of the toolhead + (setup-specific — verify per rig): features at machine X appear in frames taken from + toolhead X+90..150. The far-X column of a bed survey is therefore the only view of the + bed centre-right. +- **Bed map (operator-stated + survey 25c4f87a, 2026-09-01)**: rotary module along the bed + centre at **machine X≈170**, axis along Y, chuck at the back (~Y250–320), yellow tailstock + at the front; tool setter top-left. Both stored as landmarks (`rotary-axis`, + `tool-setter`). +- **Silent non-motion signature**: the controller can reply `ok` to a direct move and not + move at all (settle times out with position unchanged; observed once 2026-09-01, suspected + enclosure door open — unconfirmed). The verified-settle contract catches it; do not trust + an `ok` alone. +- Fleet: machine named "Snapmaker" @ 192.168.1.173 = the A350 CNC; "F350" @ .130 = the + 3D printer.

On this +controller `G53` on its own line is modal until a `G54..G59` reselects a work workspace - every +emitter here relies on it (`G90` / `G53;` / moves / `G54;`; Luban's Home is `G53;G28;G54`) - and an +inline `G53 G0 ...` is NOT honoured (the move runs in the selected workspace; `validateGcode` flags +it). Agents plan, stage, record and quote in MACHINE coordinates; the work origin belongs to the +operator, Luban and the firmware (touchscreen, tool-change wizard), persists across homing, dies +on a machine reboot, and is written by the MCP only through `apply_tool_length_offset`. + +**The position of record** (`machinePosition.ts`, consumed via `getPositionSnapshot`). The 2 s +WiFi status poll can land inside a move's `G53;...G54;` window and carry either frame with the +offset populated, zeroed or missing; hand-deriving `machine = work - originOffset` on such a beat +produced Z 555 / Z 656 "positions" that passed the traverse-height guard and every landmark +clearance, and the Workspace console printed its own copy of the subtraction. Now ONE judge sees +each distinct beat and returns `machine` + `reliability`: + +| `reliability` | Meaning | Motion / staging | +|---|---|---| +| `verified` | the controller's echo of the last commanded move (positionOfRecord) is still valid for the current gcode sequence - it outranks the beat | allowed | +| `heartbeat` | coherent beat, offset reported by the controller | allowed | +| `cached-offset` | coherent beat, missing/zero offset replaced by the last complete one (a zero is believed only after 3 quiet beats) | allowed | +| `awaiting-resync` | the beat was REJECTED - derived value more than 50 mm outside the travel, a frame-flip signature (raw jumped by exactly the offset), or no offset reported yet - and `machine` is the last accepted position with its own timestamp | **refused** until the next coherent beat | +| `stale` | no report for more than 10 s | **refused** | + +Rules the judge follows, in the operator's words: an incoherent beat is IGNORED, never +reinterpreted - the next coherent sync rectifies it; a coordinate more than 50 mm outside machine +bounds is a mistake, never a position; nothing is assumed when no offset has been reported. All +state (cached offset, zero streak, previous accepted raw, last accepted position, trusted offset, +echo record) is forgotten on every (re)connection. `assertFreshHeartbeat` - in front of every +procedure start, direct move, job start and Z staging, never inside a runner's per-move loop - +refuses on `awaiting-resync`/`stale`, so a rejected G53-window beat can delay a start by one poll +period but cannot abort a running procedure or reach a guard as a number. `get_position` returns +the judgement (`reliability`, `frame`, `reasons`, the rejected beat's `derived` value for +diagnostics); the console shows the raw report as `report pos(...) offset(...)` and the judged +position as a separate `mcp:position` line (`machine(held ...)

The build dirties `src/package.json` and + `MaterialTestGcodeParams.jsx` — revert before staging. +- **Stack**: stacked single-commit PRs `mcp/N-*`, each targeting the previous branch + (#15 → #79 as of 2026-09-05, then `mcp/46-position-of-record` (#80), `mcp/47-timing-inline-g53` (#81), + `mcp/48-new-stock-survey` (#82), `mcp/49-cam-probing-gcode` (#83), `mcp/50-simulator-spec` (#84, docs); + next `mcp/51`. #70 stale- + heartbeat, #71 probe_sequence, #72 GPIO probe feed, #73 Linux/mac packaging, #74 machine + settings + docs, #75 sensor toggles + LAN, #76 job events + even survey, #77 offset + transient + detached procedures, #78 surface scans, #79 console input leak, mcp/46 position + of record + diagnostics; origin = Snapmaker/Luban is NEVER pushed). Mid-stack changes: + amend + rebase the chain. commitlint enforces `Type: Sentence-case subject` (20–100 + chars). +- **Credentials**: active gh account is `tyeth-ai-assisted` (no push). Per-command + override only: `GH_TOKEN=$(gh auth token -u tyeth)` for gh calls; + `git -c "credential.helper=!f() { echo username=tyeth; echo password=$GH_TOKEN; }; f" push ...`. + Never `gh auth switch`, never store the token. +- eslint judged against baseline (pre-existing errors in ConnectionManager/SstpHttpChannel + stay); `npx tsc -p tsconfig-server.json --noEmit` filtered to `services/mcp` must be + clean; `npm run test:mcp` (node:assert tests for the pure modules - validator, + machinePosition, envelopeChecks; add a `tests/*.test.ts` and register it in `tests/run.ts`) + must pass. +- **Timing diagnostics (`diagnostics.ts`, 2026-09-05)**: in job 1db4902a4cd6 the 0.1 mm fine + steps took ~370 ms at the controller plus a 100 ms sensor window, yet one step in four + idled 1.3–2.1 s between the controller's reply and the next send, and the resumptions fell + on a strict ~4 s grid — every echo matched, so the settle wait was NOT involved; something + periodic held the server's timers (event-loop block or CPU starvation on the Celeron box; + the renderer console and GNOME Remote Desktop are suspects). Evidence is now recorded as + **job events in sequence with the gcode traffic**: `event_loop_stall` (100 ms ticker > 250 ms + late), `heartbeat_gap` (> 4.5 s between beats), `heartbeat_frame_flip`, `slow_step` (> 750 ms + from the previous reply to the next send inside a job), `sense_overrun` (sensor window + finished > 200 ms late), `position-estimated`; every `gcode` event carries `execMs` + (send → reply) and `idleMs` (previous reply → this send); probe-feed readings carry + `pipeMs` (GPIO monitor detection → server). Totals via `get_mcp_diagnostics` (also in + GET `/api/mcp`). The job event log keeps 2000 events (was 400 — a scan overflowed it) and + pages by `seq`, so `since_event` / `next_event_index` stay valid after the cap trims the + middle. On GPIO the sensor lead over the controller reply was 5–144 ms on all 14 contacts + of that job: `sensor_delay_ms` 50 is ample there; the surface-scan floor is 30. + **Second run (job d8f6ec1b5c11, mcp/46 build)**: event loop clean (0 stalls, max lag 119 ms), + heartbeat mean 1.99 s with 0 gaps, sensor pipe < 3 ms — yet 56 `slow_step` events totalling + 159 s of 492 s, every echo matching, each long one (3.5–4.6 s = two beats) landing ~2 s + after a `heartbeat_frame_flip`, the short ones (1.1–1.6 s = one beat) every third + descend/coarse step. The step path has no await but two timers, so the send events now + carry the breakdown `replyToSenseEndMs` / `senseMs` / `senseWindowMs` / `senseEndToEngineMs` + / `engineMs` to say which segment holds the time. **Third run (cdbc29371b97)**: the whole + idle is `replyToSenseEndMs` (sense 50–52 ms, engine 0–1 ms) — i.e. between the controller's + reply and the sensor window opening, inside the move's return path, with every echo + matching in the work frame. The code there is synchronous plus promise resumptions, so the + send events now also carry a `trace` of wall-clock marks (`reply-returned`, `echo-match` / + `echo-miss` / `echo-absent`, `engine-exit`, `settled-exit`, `sense-start`, `sense-end`, + `engine-enter`) and a `settle-wait` / `settle-done` event fires whenever the heartbeat + fallback runs at all. **Fourth run (70b2b8c675a6, 11 stations, 587 s) named it**: all 84 + `settle-wait` events carried `offset: 0,0,0` from the heartbeat. A G53-window beat reports + `offsetX/Y/Z` as **(0, 0, 0)** (not missing) with `pos` in machine coordinates, so the + work-frame echo matched neither frame and the engine waited one beat (two after a flip) — + ~180 s of that scan. The same beat, read by the runner before the descent to station 1, + turned a verified Z320 into "Z−8", skipped the fast descent and aborted the scan at the + station check (job 42df7b9351b7; GPT-5.6 agent's write-up + `ROTARY_SCAN_POSITION_RECHECK_ISSUE.md` on the box). Fix: `judgeOffsetReport` + (positionOfRecord.ts) — a zero offset that contradicts a non-zero offset seen on this + connection is a transient until reported on 3 distinct beats in a row (a real zero origin + persists); `getPositionSnapshot` uses the cached offset meanwhile (`originOffsetSource: + cached`, warning); runners take their current Z from `knownMachinePosition()` (the + position of record first) and abort if the toolhead is already BELOW the descent target; + diagnostics count `zeroOffsetBeats`; `get_mcp_diagnostics.originOffset` shows the cache and + streak. **Fifth run**: the descent fix held (`descend-from Z320 (record)`), but 28 + `settle-wait`s remained, all zero-offset, stations 47–54 s — a scan stepping every second + keeps the poll inside G53 windows for beats in a row, so the 3-beat streak *accepted* the + zero (125 zero-offset beats). Two more changes: (1) only QUIET beats count towards + believing a zero — none while direct gcode is in flight or replied within 3 s + (`directGcodeQuiet`); a real touchscreen re-zero happens idle and is believed after ~6 s; + (2) the engine keeps its own **trusted offset** (the one that last proved an arrival via echo + or settled heartbeat) and judges echoes with it FIRST, the heartbeat's offset second + (`matchFrameWithOffsets`), so the echo path no longer depends on the per-beat value at all; + `settle-wait` events print `trustedOffset`, `get_mcp_diagnostics.originOffset.trustedByEngine` + shows it. +- **Stale post-hop beat read as drift (job de932e286afd, 133-station grid, aborted at r2c10 + after 29 contacts; GPT-5.6 agent's retest note)**: a 4 mm hop's echo verified X174 and set + the record; the next status report, stamped ~750 ms later, still showed the previous + station X178 (the poll samples the machine before its response is processed). The + re-check read that ONE beat twice 250 ms apart, and `reportTime` derived as + `Date.now() − reportAgeMs` differed by 1 ms between the reads, so "two distinct agreeing + beats" fired and the scan aborted. Fixes: snapshots carry the beat's own `reportedAt`; + two reports are distinct only ≥ 1 s apart; the record remembers `previousMachine`, and a + report still showing that position is stale by definition (never drift evidence — the + 4.5 s deadline still aborts if nothing ever catches up). Unit checks replay the abort. +- **Buffer sizes** (Settings → MCP Server → Diagnostic buffers, or env): `mcpJobEventLimit` / + `LUBAN_MCP_JOB_EVENT_LIMIT` (default 2000, 400–100000 events per job) and + `mcpDiagnosticsRecentLimit` / `LUBAN_MCP_DIAGNOSTICS_RECENT_LIMIT` (default 40, 10–10000 per + list). Applied immediately. Measured (cdbc29371b97, 8-station path, z_safe_delta 20, coarse 1, + fine 0.1, 3 confirm passes): 763 events ≈ 100 fixed + ~85 per station; budget + `100 + stations × 120` — the default covers ~15 stations, a 10 × 10 grid needs ~12 000. + `job.result` is stored outside the log and is never trimmed; `eventsTotal > eventCount` + flags a trimmed log. The cnc-probing skill tells agents to ask the operator to raise the + limit before staging a scan that would overflow it (no MCP tool changes it, by design). +- **Claude Code caches MCP tool schemas at session start**: after a server rebuild that adds + or changes tool arguments, the client strips the new args (`additionalProperties: false`) + until Claude Code restarts — or use a raw JSON-RPC helper + (`C:/dev/software/snapmaker/.tools/mcp-call.js`, or a urllib one-liner against + `http://127.0.0.1:40889/mcp` on the box) in the meantime. +- **Where operator state lives** (per machine running Luban — it does NOT sync between + rigs): configstore `~/.snapmaker-luban.json` (`mcp*` keys incl. `mcpToolSetter`, + `mcpToolRegion`, `mcpSafeTraverseZ`, `mcpMaxJogDistance`); userData + (`%APPDATA%/snapmaker-luban` or `~/.config/snapmaker-luban`): `machine.json` (the app's + Machine Settings), `mcp-landmarks.json`, `mcp-camera-calibration.json`, `mcp-surveys/`. + While Luban runs, change state only through the MCP tools (`set_tool_setter_config`, + `set_landmark`, `set_tool_region`, `set_camera_calibration`) or the app UI — the + configstore file is rewritten on save. Migrating a second rig = replaying those tool calls + and copying `mcp-surveys/`. +- **Startup facts**: cold services-ready was ~13 s → ~6 s post-reboot after the server bundle + (#57), ~0.7 s warm; the remaining cold cost is the keep-external packages. A Chromium HSTS + file can replace the userData directory ~11 s after launch (boot/quit guards rename it + aside, #63). Dev runs report app version 15.5.7 to the updater (Electron's own version — + benign). +- **Assistant-tooling gotchas**: on Windows Git Bash, python passed through a Bash heredoc + gets its backslashes halved (a written `\r` arrives as a real CR) — build escapes with + `chr(92)` or use the editor tools, and always re-read the patched line. skill-creator's + scripts (validator/packager) read files in the locale codepage — run them with + `PYTHONUTF8=1`; the canonical skill-creator source is `anthropics/skills` (takes external + PRs), while `anthropics/claude-plugins-official` is a mirror that auto-closes external PRs; + the UTF-8 fix already has open PRs upstream (#1591 et al.) — don't add another. + +## Deployment notes: the Ubuntu MCP box (2026-09-04) + +The second rig (x86_64 Ubuntu 24.04, Celeron N4020, hostname `pi-iOTA-Flo-360`, user `pi`, +LAN 192.168.1.153 — not a Raspberry Pi) runs the `.deb` with the GPIO probe transport and the +toolhead camera. Everything a fresh install needs: + +- **Sensor bridge**: an Adafruit **KB2040** running U2IF (`239a:0105`, Blinka board id + `KB2040_U2IF`, pin names `D*`/`A*`). Wiring (operator, bump-tested 2026-09-04): probe + **A0** (idles driven HIGH → `inverted`), tool setter contact **D2** (idles LOW), setter + overtravel **D3** (idles LOW); all three lines are actively driven, so pulls are a + don't-care in operation — configured fail-safe (`A0:down`, `D2:up`, `D3:up`: a broken wire + reads *triggered*). Pushing the setter plunger ~1 s past contact trips overtravel. +- **udev**: pip `hidapi` uses the **libusb** backend, so the rule must open the USB device, + not just hidraw — `/etc/udev/rules.d/99-u2if.rules`: + `SUBSYSTEM=="hidraw", ATTRS{idVendor}=="239a", ATTRS{idProduct}=="0105", MODE="0660", GROUP="plugdev", TAG+="uaccess"` + and the same line with `SUBSYSTEM=="usb"`; then `udevadm control --reload-rules && + udevadm trigger`. Symptom without it: `OSError: open failed` from `hid.device.open`. +- **Verify wiring** with `.venv/bin/python src/server/services/mcp/gpio_bumptest.py --seconds 90` + (reads the configstore, prints raw → idle/TRIGGERED, flags a resting-state-triggered + channel = wrong polarity). +- **Cameras**: two are attached. The **toolhead camera is the Sonix "USB 2.0 Camera"** + (pinned by `/dev/v4l/by-id/usb-Sonix_…-video-index0`); at the homed position it looks + straight at the enclosure's aluminium extrusion, which reads as a near-field silver strut + on a dark textured background — that IS the toolhead view, not a stray camera. The + icspring camera (wide, warm view of the MDF wasteboard) is the other one. `/dev/videoN` + numbers reshuffle on replug; always pin the by-id entry. +- **Launching**: Ubuntu 24.04 needs the AppArmor `userns` profile the `.deb` postinst + installs (see Installing); until then `snapmaker-luban --no-sandbox`. To launch into the + operator's GNOME/RDP session from ssh, borrow `DISPLAY`/`XAUTHORITY`/`WAYLAND_DISPLAY` + from a session process's `/proc//environ`. +- **State**: a fresh box has NO operator state — replay it through the MCP tools (see + "Where operator state lives" above); this bit us on 2026-09-04 when an agent correctly + refused to run the tool setter because the reference was empty. + +## Open threads + +- **#50–#53 implemented** in `mcp/22-stored-state`: landmark registry (`set_landmark`, + surfaced as `nearbyLandmarks` on captures within 120 mm), calibration `surface` tag + + automatic Jacobian-prediction divergence warning in `visual_servo`, `expected_shift` + tie-breaking in `track_feature` (reports `chosen_by`/`raw_best`), and `get_stored_state`. + Seed the landmark registry with the tool height checker (machine Y≈176–340). +- **#38 startup socket.io gap** — properly belongs in the startup stack; hotfixed here. +- **#24 measurement systems, #25 collision watcher** — designed but not started. +- **CNC touch probe (next)**: a normally-open touch probe in the spindle, reporting on the + probe feed channel (config already carries `mcpMqttFeedProbe`), combined with the camera + to measure work from the top and sides in any position including on the rotary axis. + Long term: a manual probe/inspection file driving a probing session, and a report + exportable to CAD/CAM (Fusion + free tools). The tool setter's staged + approach/release/confirm runner in `toolSetter.ts` is the motion template. +- **Probe transports**: the USB-GPIO transport landed 2026-09-03 (Blinka/U2IF backend in + `gpioFeed.ts`, behind the `ProbeTransport` contract — consumers still only see the + `ProbeFeedService` surface). Remaining ideas from the 2026-08-31 operator note: an HTTP + service (e.g. a Pi running Python with a USB camera plus GPIOs — its camera half + already fits `mcpCameraUrl`), and UART sensors through the same U2IF Pico. With local + GPIO the `sensor_delay_ms` contact windows and release timeouts can collapse to near + zero — the defaults are still MQTT-sized, so tighten them per-call when running on + gpio. + +- ~~Procedure results only travel on the `start_gcode_job` response~~ — done 2026-09-05: the + runner outcome is stored as `job.result`, every job carries an event log (state changes, + runner phases, gcode traffic while active, file-job progress), and `get_gcode_job_status` + long-polls (`wait_ms`, `since_event`) — agents no longer read server logs to learn how a + job went.

Governing principles + +**Camera geometry is session state.** + +- Nothing converts a pixel into a machine coordinate, or a machine coordinate into a viewing + pose, until a camera model has been solved *and verified in this power cycle*. A plain + capture is always allowed: a frame FINDS things, it clears nothing (law 3). +- The model is bound to evidence, not to time: a fingerprint (device, resolution, reference + frame hash) plus a connection epoch. A reboot, a reconnect, a different camera or a failed + verification all mark it unverified. +- The bootstrap must work **from nothing** — no assumed direction, offset, field of view or + lens. Doctrine may describe the method; it may never carry the numbers. + +**A clearance is a property of the obstacle, not of the tool.** + +- `clearance_z` states how tall the *obstacle* is. The server adds the current tool's + protrusion and a margin to decide the minimum toolhead Z. An unknown tool resolves to the + longest bit in use, and if even that is unknown the crossing is refused. + +**The motion floor and the park height are different numbers.** + +- The **motion floor** (320) is the lowest Z at which XY transport may happen at all. +- The **park/traverse height** (328) is where procedures hop between stations, retreat on + abort, and finish. Nothing about that changes. + +--- + +## 3. Why the floor and the clearance basis are one change + +From `README.md:594-604`: job 34d787bdb2d7 lost its last op because the `rotary-axis` +landmark declares clearance **328** while the traverse height was then **320** — a hop at 320 +*outside* the rotary footprint was refused. The fix at the time exempted segments at or above +the traverse height from crossing checks, which also let a traverse cross the rotary box with +8 mm of headroom nobody had measured. The operator then set the traverse height to 328 and +removed the exemption. + +The rotary's clearance is 328 because it had to cover a fitted touch probe (~71–73 mm) on top +of the physical hardware. That single number conflates obstacle height with tool length, and +because it conflates them it had to be set to the machine's ceiling — which is why the floor +had to rise to meet it. + +Separating the two numbers dissolves the knot: the rotary box gets its *physical* top, +the checker adds the live tool protrusion plus a margin, and a hop at 320 over clear bed +passes while a hop over the rotary is judged on measured quantities instead of a blanket +ceiling. **This is why B lands before C in the stack.** + +### The risk, stated plainly + +Dropping the blanket floor from 328 to 320 removes 8 mm of *blind* protection — the margin +that guards things nobody has entered in the landmark registry (clamps, stock, vises, +fixtures). After C, an unmapped object taller than ~320 minus the tool length is protected by +nothing. Mitigations built into the stack: + +- The floor is a config value (`mcpMotionFloorZ`, default 320) — one setting reverts it. +- C ships only after B, so the registry is expressed in physical heights and can be trusted + to do the work the blanket floor used to do. +- `get_stored_state.limits` reports both numbers, and the landmark report names every box + still on the legacy basis. +- The operator confirms once that nothing unmapped on the bed stands above the floor minus + the longest bit.

Six approvals, three +wrong poses and a re-home become two approvals and a model that says how far it can be +trusted — while transport gets 8 mm of working room back, paid for with clearances that are +now measured quantities rather than a ceiling. + +## 6.

A longer baseline sharpens standoff and tilt + considerably. +3. `CLEARANCE_MARGIN_MM` default 5 — too tight, too loose? +4. Is the tool setter always fitted and always at its stored coordinates? It is the best + bootstrap target; if it can be absent we need a declared fallback, not an improvised one. +5. Tailstock and chuck-face Y: operator-stated once per rotary fitting, or worth probing? +6. How far does the camera typically move between power cycles?

Frame handling is where a probing translator + actually kills a probe. + +5. **`converted-mine/openbuilds-probexyz-annotated.nc` - metadata to report, + end to end.** Parse, simulate three contacts at known positions, then render + all four report formats. Assert: `renderFusion` emits three `G800` lines with + `I J K` equal to the stated normals `(0,0,1)`, `(-1,0,0)`, `(0,-1,0)` and + `U`/`L` equal to `0.050`; three `G801` lines follow with the work-frame + contacts; a simulated *miss* on probe 2 drops only its `G801` and leaves the + `G800`; `renderCsv` reports `deviation_mm` signed along the normal and + `within_tolerance` false when the deviation exceeds 0.050; `renderGrbl` emits + `[PRB:...:0]` for the miss. Also feed it the *unannotated* twin and assert + the nominal falls back to the programmed target and the normal to the reverse + of the probe direction. **Then assert against Autodesk's own contract, not + ours:** `O` must be the inspection surface offset (0 when we have none), not + the tip radius; and the file must carry the + `START / RESULTSFILE / DOCUMENTID / MODELVERSION / TIMESTAMP / TOOLPATHID / + TOOLPATH / G331 / G330 / ... / END` envelope that + `fusion/autodesk-postlib/inspection-cps/result generator probing.cps` writes. + Diff our output against `fusion/forum-samples/13_haas_ngc_DPRNT_OUT_inspect_surface_results.txt`, + a genuine machine-written results file; two of the three findings in + section 2 are outright bugs in `renderFusion` today. And if we ever write an + importer, `fusion/forum-samples/05_..._missing_decimals.txt` and + `06_..._g800_mislabelled_g801.txt` are two real broken files to reject + loudly. + +6. **Refusal set - assert we say no, with the right message.** Take, unmodified: + `probe-basic/.../probe_round_pocket.ngc` (macro variables), `cncjs-macros/Hole_Center.macro` + (`%VAR` and `[expr]`), `cncjs-macros/Precision_ToolChange_Macro.txt` (also + `M6`), `linuxcnc/gridprobe.ngc` (O-words), `openbuilds/PROBEX.PRB` (a `$J=` + jog line), `fusion/autodesk-postlib/inspection-nc/fanuc inspection.nc` + (`M3`, `M6`, `G28`, arcs).

Separately assert the fitted centre repeats across runs + within the unidirectional repeatability, and that the ID-versus-OD diameter + difference equals exactly `2 x effective tip radius` - never the physical ball + radius. + +8. **Gauge block - probed length.** Probe opposite faces of a grade-0 ISO 3650 + block, nominal 25.000 mm. Assert + `|probed_length - 25.000| <= 0.00014 + 2 x probe_repeatability`, i.e. + **<= 0.00214 mm** for a 1 um 2-sigma probe. Because the block is 20x tighter + than the probe, **any failure here is the probe or the translator, never the + block** - which is exactly what makes it the best first hardware test. + +9. **1-2-3 block - corner and block routines, MillenniumOS's own assertions.** + Run our corner routine against a 1-2-3 block on nominals 25.4 / 50.8 / + 76.2 mm. Assert, exactly as MillenniumOS does, that + `deflection = (measured - nominal)/2` is **>= 0 on both axes** (a negative + value on an external feature is a sign error, and MillenniumOS treats it as a + bug) and **<= 0.05 mm**; and that adjacent probed faces are perpendicular + within **0.0076 mm over 25.4 mm**. Also assert the fitted corner agrees with a + caliper-measured edge within 0.05 mm - the caliper is the weakest link, so + band it honestly. + +10. **Calibration sphere - 25-point ISO 10360-5 form check, and the repeat gate.** + Probe the prescribed 25 points on a Ø25 mm calibration sphere, least-squares + fit, and assert `P_FTU = r_max - r_min <= P_FTU,MPE` (**<= 0.001 mm** + strain-gauge, **<= 0.004 mm** kinematic) and + `P_STU = |fitted_radius - certified_radius| <= P_FTU,MPE`. Then assert the + MillenniumOS convergence gate on a single point: repeated probes converge + within **0.01 mm in at most 10 attempts** at 300-then-50 mm/min with a 2 mm + dive. This is the honest end of the survey: it is the only test that + separates "our maths is right" from "our machine is good enough". + +--- + +## Gaps I could not fill + +Stated plainly. + +- **No upstream project commits a sample of its own probe-result file.** Not + LinuxCNC, not bCNC, not ioSender.

No `G17` (`// writeBlock(gPlaneModal.format(17));` is commented out in + `onSection`; `onCycle()` does write `G17`).

Without it, imported points cannot be attributed. **Fix: + have the post write the id into the program (`(RESULTS toolpathid=1.00001 toolpath=INSPECT_TOP)`) + and echo it in the report before each group.** +3. **No `G330`/`G331`.** For a flat, untilted setup these are effectively identity and their absence + may be tolerable; for a **3+2 job they are exactly the information that says which rotated work + plane a point was measured in**, so a rotary inspection import without them will place points + wrongly. **Fix: the post must emit its CAD/workplane transforms into the program as metadata (per + B station), and `renderFusion` must reproduce `G330`/`G331` per group** — this is the single most + important report change for 3+2. +4. **`O` means the wrong thing.** We write `O`; Autodesk writes + `O` (a stock/offset allowance on the inspected surface), and the + tip radius belongs in `G801`'s `R` only. **Fix: `O` should be the surface offset (0 when unknown, + sourced from a new `offset=` key in the `(PROBE …)` comment), never the tip radius.** +5. **Number formats.** We print `X/Y/Z` and `O/U/L` with 3 decimals and `I/J/K` with 4; Autodesk uses + 4 for `xyzFormat` and 6 for `ijkFormat`. Probably tolerated, but it silently truncates our + 0.001 mm resolution and normals. **Fix: 4 and 6 decimals.** +6. **Tolerance signs.** We store `upperTolMm`/`lowerTolMm` as absolute values + (`Math.abs`) and print `L`. Fusion's `operation:inspectLowerTolerance` is the parameter + as configured (commonly negative), and the Haas post's on-machine check is + `IF [dev GT ] → under tolerance`, i.e. it compares against a **signed** lower + bound. **Fix: preserve the sign from the `tol=` metadata (`tol=0.1,-0.1` in the sample program is + already signed and we throw the sign away in `parseProbeMeta`) and print `L` signed.** +7. **A miss emits only `G800`.** That matches "the point shows as unmeasured" in intent, but no + Autodesk source confirms Fusion accepts an unpaired `G800`. **Recommend also writing + `G802 N DEVIATION` … no — better: keep `G800` alone but say so in the JSON report, and treat + Fusion's behaviour on unpaired nominals as untested.** [inferred] +8. **`G801 X/Y/Z` convention is right.** Our `contactWork` is the tip-centre position + (`frame.convention` says `contacts are tip-centre positions` [verified]) and `R = tipDiameter/2`, + which is exactly what Autodesk writes. No change needed. +9. **Bug found in our own deviation, independent of Fusion.** + `probeCam.ts` computes + `deviationAlongNormal(contactWork, nominalWork, normal, …)` where `contactWork` is the + **tip centre** and `nominalWork` is the **surface** nominal [verified at `probeCam.ts:489-495` + and `inspectionReport.ts:deviationAlongNormal`]. For a perfectly-on-nominal surface this returns + `+tipRadius` (≈ +1.25 mm with the measured 2.5 mm tip), so `deviationMm`, `withinTolerance`, + `summary.maxAbsDeviationMm` and the CSV are all biased by one stylus radius. Fusion's importer + does not see this (it does its own `R` subtraction from `G801`), which is why it has not shown up. + **Fix: subtract the tip radius along the normal before computing the deviation** — + `contactSurface = contactWork - normal * tipRadius` — or pass the radius into + `deviationAlongNormal` and let it do the correction; when the tip diameter is unknown, report + `deviationMm: null` rather than a wrong number. + +### 4.4 Smallest useful change to `renderFusion` + +``` +START +RESULTSFILE -RESULTS +DOCUMENTID +MODELVERSION +TIMESTAMP + +TOOLPATHID +TOOLPATH +G331 N A..

Pattern (document in the skill): a + `sequence` whose `descend` is `{ from: "axis.z_contact", plus: , between }` + and whose probe is `dz: -1, max_travel_mm: `. The runner already segments + the descent (5 mm, F600, async crash guard) and walks the last band at 1 mm / F100. +- Cylinder cross-axis profile: `surface_path` gets an optional + `expected_profile: { circle: { center_x, center_z_contact, radius } }` (each a number or a + reference). Per station the expected contact Z is `center_z + sqrt(r^2 - (x - center_x)^2)` + with `r = radius + tip_radius`. `slowZoneFor` takes this per-station expectation instead of + the previous station; the `max_drop_mm` band is measured from the expectation, not from the + previous contact.

Substitution: the literal `${b}` in any string (ids, `name`, reference + paths) becomes the angle; inner op ids become `_b` when they contain no `${b}`. +- `MAX_OPS` 40 -> 80 after expansion; the page lists the expanded ops with one header line per + group ("GROUP faces: 4 rotations x 4 ops"). +- Test: expansion of a 2-angle group, id uniqueness, `${b}` inside a `from` path. + +### W6.

Works the same whether or not the stream is running. +- `set_tool_region` — tell the server where the tool appears in frame so captures can flag it. +- `track_feature` — normalised cross-correlation of a template between two cached frames. Use instead of eyeballing pixels. +- `set_camera_calibration` — Y/Z-keyed pixel-to-mm calibration, optional `surface` depth tag and `jacobian`. Sign-flipped matrices are rejected. +- `get_camera_calibration` / `delete_camera_calibration` — read or remove a stored calibration. +- `visual_servo` — one clamped step toward a seen target per call. Trips when the error stops shrinking or the response diverges from the calibration prediction (parallax signature). +- `survey_bed` — approved serpentine XY camera grid at gantry height; whole-bed mosaic for finding stock and fixtures. New: `overlap_fraction` + `plane_z` derive the pitch from the camera model's real field of view ("seamless" is a relationship between pitch and field of view, and a picked pitch is not one); `z_levels` runs the grid at several heights under ONE approval, each entered with XY stationary; with a verified model each pass is composed into `mosaic_z.jpg` indexed in machine coordinates, and the seams double as a drift check that marks the model unverified when overlapping frames disagree. +- *(not a tool)* Live view for humans: `GET /camera` on the MCP port (`stream_url` above) — MJPEG at `/camera/stream.mjpeg`, one JPEG at `/camera/snapshot.jpg`, `/camera/status.json`. Same LAN gate as `/mcp`; off (Settings → MCP Server → Camera) = 404. + +### The camera model (the camera is SESSION STATE, not a rig constant) + +It can sit differently after every power cycle, be knocked, be re-aimed, or be a different camera. Nothing converts a pixel into a machine coordinate, or a machine coordinate into a pose, until a model is solved AND verified on this connection. Plain captures never need one. + +- `get_camera_model {history?}` — the model, its state (verified | unverified | superseded), why it is not usable, and which tool fixes it. Read-only. +- `verify_camera_model {target, pixel_u, pixel_v, tolerance_px?}` — predict where a target of known machine coordinates should appear at the CURRENT toolhead position, compare with where it does, record the residual in px and mm. **The first camera call of any session.** Beyond tolerance the model stays unverified and says the camera has probably moved. No motion - position with `traverse_xy` first. +- `camera_bootstrap {stage, reason, ...}` — solve the geometry FROM NOTHING, two staged procedures, one approval each. `stage: "search"`: a grid at the park height bracketing the tool setter, whose machine XY is known exactly - which frames contain it gives the camera offset INCLUDING ITS SIGN with no prior assumption, and it is the only step meaningful without a calibration. `stage: "poses"`: the poses that implies, each sweeping Z from the park height to the motion floor with XY stationary. A pose the TOOLHEAD cannot reach is dropped with a reason, never quietly adjusted. +- `set_camera_model {offset, rotation, intrinsics, valid_band_z, central_region, residuals, ...}` — store a solve from `scripts/camera_bootstrap.py`. Always stored UNVERIFIED; the previous model is kept superseded, never overwritten. +- `plan_view_pose {target, toolhead_z?}` — where must the TOOLHEAD go to see this machine point? Returns the pose, the standoff and the field of view, from the model. Use it instead of computing a pose; never carry one between sessions. + +## Landmarks and scene + +- `set_landmark` — name a scene feature by machine extent, optionally with `clearance_z`. Landmarks are obstacles: planners refuse XY paths that cross them below clearance. +- `delete_landmark` — remove one. + +## Probe feed (external sensors: tool setter, overtravel switch, touch probe) + +- `get_probe_feed_status` — transport, per-channel last readings, tripwire state. +- `connect_probe_feed` — bring up the MQTT or Blinka GPIO feed; connecting arms the overtravel tripwire. +- `disconnect_probe_feed` — drop the feed. +- `clear_overtravel_alarm` — reset a latched overtravel trip. Operator's explicit word only. + +## Tool setter and tool change + +- `set_tool_setter_config` — setter centre, trigger Z with a reference bit, known bit lengths. Operator-stated values only. +- `get_tool_setter_config` — read it back. +- `run_tool_setter` — tool height measurement as one approved, envelope-bounded routine: sensor-gated 1 mm descent, release, 0.1 mm approach, confirm pass, then a Z-only raise straight up to the traverse height (machine Z328 — never the start height; `result.finalZ`). Hard floor below expected trigger. `store_as_reference` locks the new reference; `stay_at_trigger` / `start_from_current` support the swap wizard. +- `apply_tool_length_offset` — confirmed `G92` shifting work Z by the new-minus-old tool length. Keeps the work origin true across a swap without re-touching stock. + +## Touch-probe procedures (staged, one approval per circuit, results in machine coordinates) + +- `probe_point` — one axis from the current position. The atom. +- `probe_vector` — probe along any downward or lateral unit vector. +- `probe_sequence` — enumerated hop / descend / probe circuit with law-2 hops at safe traverse height; keep-out boxes honoured at plan time. +- `probe_circle` — N radial marches plus least-squares circle fit, outside a boss or inside a hole. Reports rms and residuals. +- `probe_surface_path` — N minus-Z stations along a line: per-station contact, best-fit slope, flatness. +- `probe_surface_grid` — serpentine minus-Z grid: Z matrix, best-fit plane and residuals, ASCII height map. Both scans hop at last contact plus `z_safe_delta_mm`. +- `probe_stock_outline` — from an estimate of a block, find its top, true outline and centre in one approved procedure. +- `probe_program` — composite program: an ordered list of operations, derived references, jig geometry, keep-out and groups under one approval. The new-stock survey lives here. +- `set_probe_geometry` — jig and tool constants a rotary `probe_program` can reference as the `axis` namespace. Measured or operator-stated, with a reason. + +## CAM probing programs + +- `run_probing_gcode` — stage a CAM-generated probing program (Fusion 360, FreeCAD, any Grbl/Marlin post, or hand-written). `G38` cycles are translated into staged probes, never sent raw. Returns an inspection report. +- `get_inspection_report` — re-render a finished or aborted probing run's report in another format, such as Fusion's. + +## Standing rules the tools assume + +- The endmill is always in the spindle; never plan as if the collet is empty. +- Any XY move over 1 mm is planned at the safe traverse height - machine Z328 (home). Landmarks are honoured literally: a hop at 328 clears them on its own merits, a lower hop is checked like any low segment. +- No Z motion without a direct request. "Home" always means machine home. +- Approval covers one bounded series of moves and never carries forward. A staged procedure or program is ONE approval for every move inside its envelope — the efficient lawful form. +- Every motion tool stages a job: call `start_gcode_job` with `wait_for_approval_ms` after staging; the operator's click starts it. Hand the confirm URL over as the last line of the message, alone. +- Agents plan, stage, record and quote in MACHINE coordinates. Every staged job declares its frame or is refused; `G90`/`G91` is distance mode, not a frame; never a bare frameless `Z`. +- The work origin is the operator's (touchscreen, Luban, tool-change wizard). Read it fresh from `get_position`; never assume it; never write it except through `apply_tool_length_offset`. +- `get_position.machine` is the judged position of record with a `reliability`; a reading more than 50 mm outside the travel is a bug, never a position, and is ignored until the next coherent beat. Do not derive a machine position from one heartbeat by hand. +- Canonical agent guidance: `.claude/skills/cnc-motion-rules/SKILL.md`. diff --git a/src/server/services/mcp/docs/examples/cam-tests/LICENSE-adamlange.txt b/src/server/services/mcp/docs/examples/cam-tests/LICENSE-adamlange.txt new file mode 100644 index 0000000000..a288054ab8 --- /dev/null +++ b/src/server/services/mcp/docs/examples/cam-tests/LICENSE-adamlange.txt @@ -0,0 +1,22 @@ +adamlange-probe_surface.ngc is from https://github.com/adamLange/probing_routines (probe_surface.ngc), MIT licence: + + +Copyright (c) 2020 Adam Lange + +Permission is hereby granted, free of charge, to any person obtaining a copy +of this software and associated documentation files (the "Software"), to deal +in the Software without restriction, including without limitation the rights +to use, copy, modify, merge, publish, distribute, sublicense, and/or sell +copies of the Software, and to permit persons to whom the Software is +furnished to do so, subject to the following conditions: + +The above copyright notice and this permission notice shall be included in all +copies or substantial portions of the Software. + +THE SOFTWARE IS PROVIDED "AS IS", WITHOUT WARRANTY OF ANY KIND, EXPRESS OR +IMPLIED, INCLUDING BUT NOT LIMITED TO THE WARRANTIES OF MERCHANTABILITY, +FITNESS FOR A PARTICULAR PURPOSE AND NONINFRINGEMENT.
