Snapmaker Orca V2.4.0-Beta-Release

Snapmaker Orca 2.4.0 Beta 发布。本版本功能与 Alpha 一致，集中修复了 Alpha 测试期间收集的 6 项问题（其中 2 项为崩溃类），并更新了应用图标与 Web 安装向导 / 主页 logo。欢迎大家升级体验，发现问题请通过 #840 看板或 GitHub issue 反馈。

**Note：**本版本包含 2.4.0 Alpha 的全部内容——模型选中高亮、LOD 层级细节系统、混色匹配自动模式颜色选择、高流量热端（High-Flow Hot End）参数支持、新增 6 款耗材丝及扩充颜色库、三项底层依赖大版本升级（OpenSSL 3.5.7 / macOS 构建环境 / Flutter 3.41）等，完整清单见 2.4.0 Alpha 发布公告。以下仅列出 Alpha 之后合入的变更。

---

一、修复项（Alpha 测试反馈）

1. 修复 macOS 上从 Snapmaker Space 链接打开模型被丢弃的问题。由社区用户 @KuzuriAo 报告并提交修复，非常感谢！（#851 / #852）

2. 修复发送打印时偶发崩溃的问题。设备耗材信息缓存存在双重编码时，连接成功回调会抛出异常导致进程退出；已在 C++ 与内置网页（Flutter）两侧同时修复。（#849 / #850）

3. 修复打开预设差异对比对话框时崩溃的问题。（#848）

4. 修复 macOS 内置网页加载异常的问题。网页导航现会等待处理就绪后再进行；同时新增内置网页运行状态上报（2 分钟看门狗，无论是否登录均上报），便于持续定位白屏类问题。（#857）

5. 修复 macOS 首页 / 设备页不渲染（白屏）的问题。问题源于 WKWebView 并发加载与本地网络策略限制，已在两台 macOS 机器上实测恢复。（#853 / #865）

6. 修复校准流程因配置项类型不匹配而异常的问题。系 Alpha 工艺迁移的遗留影响，涉及 enable_overhang_speed、initial_layer_speed、slow_down_layer_time 等参数。（#861）

二、其他改进

1. 更新应用图标及 Web 安装向导 / 主页 logo，含 Windows 任务栏图标显示偏小的修复。（#858 / #867）

三、升级注意事项

1. 建议 Snapmaker 设备固件升级至 2.0.0 或更高版本后再更新本版（#862）。

四、致谢

• @KuzuriAo——报告 macOS Space 链接打开模型被丢弃的问题（#851），定位根因并提交修复（#852）；同时提交了 macOS 首页渲染回归的详细分析（#853）。

• @elithecho（#854）、@Minecrafter8001（#859）、@schornhe（#864）等——感谢所有通过 #840 看板与 issue 反馈问题的 Alpha 测试用户，你们的报告让这些问题得以在本版修复或纳入跟进。

五、已知问题（跟进中）

以下问题正在核实与跟进中，进展将更新在各 issue：

• 「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）

• Orca 下发的风扇转速与 U1 实际不符（#864）

已知问题集中维护在 #840 看板（持续更新）。不确定是否重复的问题也请直接提交，重复条目由我们统一处理。

Snapmaker Orca 2.4.0 Beta is now available. This release keeps the feature set identical to the Alpha and focuses on fixing 6 issues collected during the Alpha testing period (2 of which were crashes), along with updates to the app icon and the web setup wizard / homepage logos. Feel free to upgrade and test — please report any problems via the #840 tracking board or GitHub issues.

Note: This release includes everything from 2.4.0 Alpha — highlighting for selected models, the LOD (level-of-detail) system, automatic color selection for color-match mixing mode, High-Flow Hot End parameter support, 6 new filaments plus an expanded color library, and three major underlying dependency upgrades (OpenSSL 3.5.7 / macOS build environment / Flutter 3.41), among others. For the complete list, see the 2.4.0 Alpha release announcement. Only changes merged after the Alpha are listed below.

---

1. Fixes (Alpha Testing Feedback)

1. Fixed an issue on macOS where models opened from Snapmaker Space links were dropped. Reported and fixed by community user @KuzuriAo — many thanks! (#851 / #852)

2. Fixed an occasional crash when sending a print job. When the device filament information cache was double-encoded, the connection-success callback would throw an exception and terminate the process; the fix has been applied on both the C++ side and the embedded web (Flutter) side. (#849 / #850)

3. Fixed a crash when opening the preset comparison (diff) dialog. (#848)

4. Fixed abnormal loading of embedded web pages on macOS. Web navigation now waits until processing is ready before proceeding; a runtime status report for the embedded web pages has also been added (a 2-minute watchdog, reported regardless of sign-in status) to help keep diagnosing blank-screen issues. (#857)

5. Fixed the Home / Device pages failing to render (blank screen) on macOS. The issue stemmed from concurrent WKWebView loading combined with local network policy restrictions; the fix has been verified on two macOS machines. (#853 / #865)

6. Fixed calibration failures caused by mismatched configuration value types. This was a lingering effect of the Alpha's process migration, affecting parameters such as enable_overhang_speed, initial_layer_speed, and slow_down_layer_time. (#861)

2. Other Improvements

1. Updated the app icon and the web setup wizard / homepage logos, including a fix for the Windows taskbar icon rendering too small. (#858 / #867)

3. Upgrade Notes

1. We recommend upgrading Snapmaker device firmware to 2.0.0 or higher before installing this version (#862)

4. Acknowledgements

• @KuzuriAo — reported the issue of models being dropped when opened from Snapmaker Space links on macOS (#851), located the root cause and submitted the fix (#852), and also provided a detailed analysis of the macOS Home page rendering regression (#853).

• @elithecho (#854), @Minecrafter8001 (#859), @schornhe (#864), and others — thanks to all Alpha testers who reported issues through the #840 tracking board and GitHub issues; your reports made it possible to fix these problems in this release or take them into tracking.

5. Known Issues (Under Investigation)

The following issues are under investigation and being tracked; progress will be updated in the respective issues:

• In the "Upload and Print" dialog, the printer dropdown shows no printers the first time it is opened, and the "Add Printer" dialog cannot be closed (#854)

• The U1 default filament-change G-code poses a head-crash risk in one-at-a-time (sequential) printing mode (#859)

• Fan speeds sent by Orca do not match what the U1 actually runs (#864)

Known issues are centrally maintained in the #840 tracking board (continuously updated). If you are unsure whether an issue is a duplicate, please file it anyway — we will consolidate duplicate entries on our side.

诚邀参与 Alpha 测试
本次 2.4.0 Alpha 除新增一批功能（见上方更新日志）外，还完成了三项底层依赖的大版本升级——此类组件平时稳定运行、最易被忽视，也最难通过内部测试完全覆盖。

点击展开查看依赖升级清单

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

我们已在主流打印机型号上验证核心流程（导入 → 切片 → 发送打印 → 设备监控）可正常运行；但各类系统版本、旧固件、自建打印服务器、弱网等环境，仍需依靠真实使用加以覆盖。在非主流路径上遇到问题属于预期现象——每一条反馈都直接影响正式版质量，遇到问题请直接提交反馈，无需先行排查。

以下环境我们内部最难覆盖，诚挚欢迎相应设备的用户参与验证：

• macOS 旧系统用户（本次构建环境为历次最新，旧系统是差异最大的组合），以及已升级 macOS 26 (Tahoe) 的用户（建议进行一轮快速验证）
• 弱网 / 企业网络 / 代理环境用户

三项升级可能引发的问题

• 网络与设备连接：登录失败或报证书错误、模型/预设下载失败、局域网找不到设备、发送打印失败、设备状态不刷新、熄屏后联机异常（Windows）

• 内置网页：首页/登录/模型库/设备页白屏、样式错乱、中文输入异常、按钮点击无响应

• macOS 专属：首次启动 Gatekeeper/公证校验异常（"已损坏/无法验证"）、旧系统上启动或渲染异常、界面细节回归（深浅色、字体、表格线）；如遇启动即闪退，请立即反馈，此类问题对定位最有价值

• 不受影响：本地导入、切片、导出 G-code 到 U 盘等纯离线流程未涉及本次升级组件

升级注意事项
工艺预设已精简合并：同层高不同品质的预设（Fine / High Quality 等）已并入 Standard。如您有基于这些预设的自定义工艺，升级后请对照上方更新日志中的映射表检查参数是否符合预期——如发现映射有误，同样属于有效反馈，欢迎提交。

已知问题
已知问题集中维护在 #840（持续更新）。如无暇逐一核对，不确定是否重复的问题也请直接提交，重复条目由我们统一处理。

建议测试清单（约 30 分钟，按样本缺口程度排序）

1. 冷启动 → 遍历设置页签（关注是否存在闪退或卡死）
2. 登录账号 → 首页 → 下载模型（OpenSSL：登录与下载链路；本次包含多项登录链路修复，建议重点验证）
3. 切片 → 局域网发送打印 → 设备页状态实时刷新（OpenSSL：设备联机链路）
4. 自建打印服务器用户：连接并上传一次 G-code——目前测试样本最匮乏的场景
5. 逐页打开首页/登录/模型库/设备页/校准等内置页面（Flutter：观察白屏、样式错乱、按钮无响应；可再于弱网或热点环境下复测一遍）
6. macOS 用户：分别在深色与浅色模式下检查主窗口与设置页；macOS 12–14 用户额外留意启动和画布渲染
7. 高流量热端：按《U1 热端使用指南》选择对应耗材与工艺切片打印，确认参数生效

反馈方式
反馈渠道：GitHub Issues。本次 Alpha 版本的反馈收集期约为一周以上，之后我们将汇总反馈并发布正式版。

• 最低要求：提供一张截图或一段录屏，并简述操作步骤与异常结果即可，其余信息我们将跟进询问

• 信息越完整，定位越快（尽量包含）：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、实际现象与预期结果；日志——配置目录下 log/ 文件夹最新日志

• 崩溃：崩溃后如弹出上报提示，请选择上报（Alpha 版本崩溃会自动标记回传，是定位最快的途径），并补充说明当时正在进行的操作
  如您使用的机型属于主流列表且全流程顺利，也欢迎回复一句"型号 X + 固件 Y，全流程通过"——这对我们判断风险是否收敛同样重要。

安装与回退
安装 Alpha 会沿用现有配置。新版可能对配置做单向迁移，装回正式版未必完全恢复，安装前请完整备份配置目录：

• Windows：%AppData%\Snapmaker_Orca\
• macOS：~/Library/Application Support/Snapmaker_Orca/

回退到正式版：建议先完全卸载 Alpha，再重新安装正式版

(2) Subdivide Mixing Layers

Subdivide mixing layers	Full domain	Apply subdivision to infill
When enabled, layer height for mixing areas will be subdivided for better color mixing results.	When enabled, subdivided layer height applies to all mixed-color regions on outer walls, whether the colors are created by painting or filaments changes.	When enabled, infill within mixed-color regions is subdivided using the same settings.

2. Added support for new filament types for the Snapmaker U1.
