[2.4.0 Alpha] Known Issues & Feedback Tracker · 已知问题跟踪板

[zhangzhend0ng]

This is the known-issues board for the Snapmaker Orca 2.4.0 Alpha.
Check this list before reporting — but if you are not sure whether your problem is already known, report it anyway; we will deduplicate.

Why this Alpha exists

2.4.0 Alpha upgrades three foundational dependencies. Core workflows (import → slice → send to printer → monitor) have been verified internally on mainstream printer models; problems on less common paths are expected — collecting them is exactly what this Alpha is for.

Component	From → To	Scope of impact
OpenSSL (network security library)	1.1.1w → 3.5.7 (LTS)	All networked features: sign-in, downloads, sending print jobs, device connectivity
macOS build environment	CI moved from macos-14 to macos-15 (macOS 15 host + Xcode 16 toolchain)	macOS builds: packaging/signing/notarization, older-OS compatibility, toolchain-level differences
Flutter (embedded web framework)	3.24 → 3.41	Embedded web pages: Home, sign-in, model library, device page, calibration

Known issues

• "Upload and Print" printer dropdown empty on first open; "Add Printer" dialog cannot be closed — #854
• U1: default change-filament G-code may cause head crashes in object-by-object printing — #859 (fix planned)
• Fan speed values sent from Orca differ from what U1 applies — #864 (under triage)

Fixed in subsequent builds

All fixes below are merged to main and will ship in 2.4.0 Beta:

• Fix macOS Home / Device pages failing to render (white screen) — #853, fixed by #865; confirmed loading again on two macOS machines (see macOS: Home page does not render in main, regression in 77b4d0e6..dcf8629e (suspect #818) #853)
• Fix model opened from a Snapmaker Space URL being discarded on macOS — #851, fixed by #852 (thanks @KuzuriAo)
• Fix crash when sending a print caused by a double-encoded deviceFilamentInfo cache (C++ guard + Flutter writer fix) — #849, #850
• Fix preset diff dialog crash — #848
• Fix macOS embedded web page loading (navigation now waits for the handler to be ready); added embedded-web run-status reporting — #857
• Fix calibration config type mismatches after the flow-variant migration — #861
• New Orca app icon; fix undersized Windows taskbar icon; update web wizard / homepage logos — #858, #867

How to report

• Lowest-effort report: a screenshot or screen recording plus one sentence ("what I did, and what went wrong") as a comment on this issue is enough — we will follow up with questions.
• For faster triage, include when possible: app version; OS and version (macOS users: exact minor version); printer model & firmware version (required for connectivity issues); steps to reproduce, expected vs actual; logs — the latest file under log/ in the config directory (Windows %AppData%\Snapmaker_Orca\log, macOS ~/Library/Application Support/Snapmaker_Orca/log).
• Crashes: when prompted after a crash, please allow the report to be sent (Alpha crashes are tagged automatically and reach us fastest), then add a comment about what you were doing at the time.

本 issue 是 Snapmaker Orca 2.4.0 Alpha 的已知问题集中看板。
反馈前先查这里；不确定是否重复也照报，我们来去重。

背景

2.4.0 Alpha 完成了三项底层依赖的大版本升级。主流打印机型号的核心流程（导入 → 切片 → 发送打印 → 设备监控）已在内部验证通过；非主流路径上遇到问题是预期内的——收集它们正是本 Alpha 的目的。

升级项	从 → 到	影响范围
OpenSSL（网络安全库）	1.1.1w → 3.5.7（LTS）	所有联网功能：登录、下载、发送打印、设备联机
macOS 构建环境	CI 从 macos-14 迁至 macos-15（macOS 15 宿主 + Xcode 16 工具链）	仅 macOS 包：打包/签名/公证链路、老系统兼容、工具链级差异
Flutter（内置网页框架）	3.24 → 3.41	所有内置网页：首页、登录、模型库、设备页、校准

已知问题

• 「上传并打印」打印机下拉框首次打开不显示打印机、「添加打印机」对话框无法关闭 — #854
• U1 默认换料 G-code 在逐件打印模式下存在撞头风险 — #859（已排期修复）
• Orca 下发的风扇转速与 U1 实际不符 — #864（排查中）

后续构建已修复

以下修复均已合入 main，将随 2.4.0 Beta 发布：

• 修复 macOS 首页 / 设备页不渲染（白屏）的问题 — #853，修复见 #865，已在两台 macOS 机器实测恢复
• 修复 macOS 上从 Snapmaker Space 链接打开模型被丢弃的问题 — #851，修复见 #852（感谢 @KuzuriAo）
• 修复因设备耗材信息缓存双重编码导致发送打印时偶发崩溃的问题（C++ 防护 + Flutter 写入侧双端修复）— #849、#850
• 修复打开预设差异对比对话框时崩溃的问题 — #848
• 修复 macOS 内置网页加载异常的问题（导航现等待处理就绪）；新增内置网页运行状态上报 — #857
• 修复校准流程因配置项类型不匹配而异常的问题 — #861
• 全新 Orca 应用图标；修复 Windows 任务栏图标显示偏小；更新 Web 安装向导 / 主页 logo — #858、#867

如何反馈

• 最低门槛：截图/录屏 + 一句话（"做了什么、结果不对"），直接在本 issue 评论即可，剩下的我们来问。
• 信息越全定位越快：软件版本号；操作系统及版本（macOS 注明小版本）；打印机型号与固件版本（连接类问题必填）；复现步骤、预期 vs 实际；日志——配置目录下 log/ 最新日志（Windows %AppData%\Snapmaker_Orca\log，macOS ~/Library/Application Support/Snapmaker_Orca/log）。
• 崩溃：崩溃后弹出上报提示请选择上报（alpha 崩溃会自动标记回传，是定位最快的途径），再评论说明当时在做什么操作。

Linux AppImage shows no buildplate using wayland and Nvidia GFX card (580 driver series).
Again: both OcraSlicer and BambuStudio (newest versions from flatpak) work flawlessly.

@rp86 thanks for the report and the log — it matches the white-screen class already tracked in #853, including the two PrinterWebView … The request timed out lines ~64 s after launch. We're collecting diagnostics in that issue, so I've listed the questions there and mentioned you — everything stays in one place.

One thing worth checking before testing newer builds: your log shows Orca Web 2.3.26, which is older than the current bundle. That's a quirk on our side — if ~/Library/Application Support/Snapmaker_Orca/web/flutter_web was left over from an earlier install, it overrides the copy inside the app bundle. Moving it aside makes sure you're actually testing the new page (and probably explains the version shown in your log).

(Separately, the [Orca Updater] Update install failed line for the printers staging looks like its own bug — we'll track that in a separate issue.)

[zhangzhend0ng]

@laryllan78 thanks for the report, and for keeping us honest on these — the buildplate issue is tracked in #404 (your Sep 12 update there is much appreciated), and the flatpak launch failure matches what's already been reported in #300. Both are noted as we go through this alpha feedback wave.

[birnam]

@laryllan78 ...and the flatpak launch failure matches what's already been reported in #300.

I don't think the current crash-on-startup with the flatpak is related to that report. I ran into the same issue after build_flatpak.sh and installing main today, and AI helped me trace it to the X509 default cert loading when SSL_CERT_FILE isn't set, and the fix works. Here's claude's summary:

crash-on-startup bug: Slic3r::Http::tls_system_cert_store() in src/slic3r/Utils/Http.cpp

ret = ::getenv(X509_get_default_cert_file_env());

getenv() returns nullptr when that env var (normally SSL_CERT_FILE) isn't set. Assigning a nullptr char* straight to a std::string calls strlen(nullptr) internally, which segfaults.

That code path only exists in static-linked builds (SLIC3R_STATIC=ON, which your build_flatpak.sh enables via src/slic3r/CMakeLists.txt:768). It's called unconditionally right at startup from GUI_App::on_init_inner(), before any window ever appears — Http::tls_global_init() runs first and only sets that env var if the default OpenSSL cert path doesn't already exist on disk. Since the GNOME runtime does have /etc/ssl/certs/ca-certificates.crt, the env var was never set, and the very next line called tls_system_cert_store(), crashing every time on getenv() returning nullptr. I confirmed this via gdb with the debug symbols from your build, not just from reading the code.

The fix is a one-line guard:

if (const char *cert_file = ::getenv(X509_get_default_cert_file_env()))
ret = cert_file;

Whether that's the correct fix I'm not certain, I haven't traced the SSL_CERT_FILE setting. But I think this indicates this is a different bug than [#300] references.
