flatpak install flathub com.orcaslicer.OrcaSlicerKey Highlights
- Security hardening for 3MF import blocks path traversal from crafted project files.
- A new printer-level wipe tower type setting gives more control for MMU, filament cutter, and tool changer workflows.
- Linux and Flatpak builds received major quality improvements, including startup, resizing, locale, and app ID fixes.
- The CLI no longer crashes when using --info, --slice, or --export-3mf.
- UI polish includes a dynamic title bar, accordion-style tabs, and calibration dialog refinements.
New Features & Improvements
- Tooltips now show inherited default values for more config option types.
- MMU detection is more reliable through normalized Moonraker database checks.
- Beam interlocking generation can now be cancelled while it is running.
- Snapmaker esthetic filament sub-types are recognized for better profile matching.
- Adaptive volumetric speed is now moved behind developer mode because it remains experimental.
Bug Fixes
- Fixed multi-tool extruder tab regressions, wipe tower crashes, and wipe tower boundary issues.
- Improved wipe tower warnings and validation for precise Z height and prime tower conflicts.
- Fixed Linux-specific problems including black screen startup, title bar display, and assemble crashes.
- Resolved notification, hotkey, dialog, marker visibility, and zero-top-infill loop bugs.
- Fixed Flatpak locale support, app ID migration, and decimal flush matrix values that could break firmware parsers.
Profiles & Localization
- New or updated profiles include Creality K2, Anet A8 Plus, Artillery M1 Pro, Qidi X-Max 4, and several filament presets.
- Localization updates landed for Czech, Brazilian Portuguese, Hungarian, Russian, Turkish, Traditional Chinese, and German.
