What's Changed
This is OrcaSlicer V2.3.2, the stable release. This release addresses a security vulnerability in 3MF file import, adds a configurable wipe tower type setting, delivers extensive Linux and Flatpak improvements, fixes a CLI segfault, and includes UI refinements like dynamic title bar sizing and accordion sidebar tabs.
Note
For Linux users: The official Flathub version will be available soon.
For features introduced earlier in the v2.3.2 cycle, please refer to:
v2.3.2-beta · v2.3.2-beta2 · v2.3.2-rc · v2.3.2-rc2
🌊 New Features & Improvements
-
Configurable wipe tower type by @SoftFever in OrcaSlicer/OrcaSlicer#12781
Adds a new printer-level setting to select the wipe tower type, instead of it being determined solely by the printer model. Type 2 is generally recommended for MMU, filament cutter, and tool changer setups.
-
Default values in tooltips for more option types by @valerii-bokhan in OrcaSlicer/OrcaSlicer#12508
Extends the tooltip default-value display (introduced in RC) to Percent, FloatOrPercent, String, and Bool config option types. Default values are sourced from parent profiles rather than hardcoded Orca defaults.
-
Improved MMU detection via Moonraker database by @ammmze in OrcaSlicer/OrcaSlicer#12764
Happy Hare now writes MMU lane data to the Moonraker database (similar to AFC), so detection has been normalized. The Moonraker database is checked first, providing more reliable multi-material system detection and access to vendor name data. -
Allow cancellation during beam interlocking generation by @Noisyfox in OrcaSlicer/OrcaSlicer#12759
Beam interlocking generation can now be cancelled mid-process. Previously, certain parameter combinations could cause generation to take several minutes with no way to stop it. -
Dynamic title bar with longer project names by @yw4z in OrcaSlicer/OrcaSlicer#12730
The title bar now dynamically expands to use all available space, supporting long project names with ellipsis truncation. Also fixes window buttons being clipped at minimum width on Windows and a thin titlebar on Linux. Fixes #12723. -
Accordion style main tabs by @yw4z in OrcaSlicer/OrcaSlicer#12772
main tabs now automatically collapse to icon-only mode when the window is too small, ensuring the Slice/Print buttons always remain visible. Fixes #12723. -
Snapmaker esthetic filament sub-types by @gaaat98 in OrcaSlicer/OrcaSlicer#12699
The Snapmaker Printer Agent now recognizes esthetic filament sub-types (wood-infused, matte, marble) for better profile matching instead of falling back to generic PLA. -
Move adaptive flowrate to developer mode by @Sabriel-Koh in OrcaSlicer/OrcaSlicer#12688
The "Adaptive Volumetric Speed" setting is now hidden behind developer mode, with a clarified tooltip noting it is experimental.
🛠️ Bug Fixes
-
Security fix: path traversal in 3MF import by @SoftFever in OrcaSlicer/OrcaSlicer#12860
Fixed a vulnerability where a crafted.3mffile could write to arbitrary filesystem locations via path traversal during import, potentially enabling code execution. -
Fix three regressions in multi-tool extruder tabs by @SoftFever in OrcaSlicer/OrcaSlicer#12680
Fixed dirty flags not showing for extruder-specific options, a crash when switching to non-first extruder tabs, and parameters on one extruder unintentionally affecting others. -
Fix crash when slicing multi-material print with wipe tower by @SoftFever in OrcaSlicer/OrcaSlicer#12682
Fixed a crash during G-code export for multi-material prints using WipeTower2 where mesh data was not initialized. -
Fix wipe tower positioned outside bed boundary by @SoftFever in OrcaSlicer/OrcaSlicer#12820
Fixed wipe tower being placed beyond the bed boundary after printer preset changes. The tower position is now re-clamped when presets change, and the estimated size includes the brim. Also fixes sliced results being immediately invalidated after first slicing. -
Optimize wipe tower warnings by @SoftFever in OrcaSlicer/OrcaSlicer#12821
Skips flushing volume validation for multi-tool printers (flushing volumes only apply to SEMM/BBL printers) and adds validation for conflicts between precise Z height and prime tower settings. -
Fix CLI segfault when using --info, --slice, or --export-3mf by @niccolodevries in OrcaSlicer/OrcaSlicer#12719
Fixed a segfault that made the CLI completely unusable. In CLI mode, render-data code was dereferencing a NULL plater pointer. -
Linux experience improvements by @SoftFever in OrcaSlicer/OrcaSlicer#12705 and OrcaSlicer/OrcaSlicer#12706
Fixes black screen on startup by skipping Freeze/Thaw during OpenGL loading, replaces global resize handler with dedicated edge panels for proper window resizing, and fixes the project/model name not appearing in the titlebar on Linux. Fixes #12636.
-
Fix crash on Linux when clicking assemble feature by @SoftFever in OrcaSlicer/OrcaSlicer#12739
Fixes #11715. -
Calibration dialog fixes by @yw4z in OrcaSlicer/OrcaSlicer#12702 and OrcaSlicer/OrcaSlicer#12752
Fixes incorrect validators attached to wrong controls, double-scaled text at higher DPI, UI layout refinements, and dialog sizing on Linux. -
Fix non-BBL printer filament grouping by @Noisyfox in OrcaSlicer/OrcaSlicer#12767
Fixed custom filament sequence not being properly handled on non-BBL printers by ensuring they go through the same reordering code path. Fixes #12449, #12766. -
Fix infinite loop with zero top solid infill density by @RF47 in OrcaSlicer/OrcaSlicer#12762
Fixed OrcaSlicer entering an infinite loop when top layer solid infill density is set to zero. -
Fix hidden line type markers (wipe, seam, retract) by @tome9111991 in OrcaSlicer/OrcaSlicer#12364
Fixed z-fighting where visibility markers for Wipe, Seam, and Retract/Unretract were obscured when overlaid on extrusion paths. Fixes #12100, #12556.Before After
-
Fix Flatpak locale support and app ID migration by @SoftFever in OrcaSlicer/OrcaSlicer#12751 and OrcaSlicer/OrcaSlicer#12879
Fixes translations not loading in Flatpak builds and updates the Flatpak application ID with migration code. Fixes #12714. -
Fix notifications unresponsive after G-code viewer collapsed by @derrickwzb in OrcaSlicer/OrcaSlicer#12689
Fixed notifications becoming unclickable after collapsing the G-code viewer panel. -
Fix hotkeys blocked when notification is shown by @SoftFever in OrcaSlicer/OrcaSlicer#12715
Fixed hotkeys (e.g., Tab) becoming unresponsive when notifications appear over the 3D canvas. -
Round flush volume matrix values to integers by @folofse in OrcaSlicer/OrcaSlicer#12672
Fixed decimal values in the flush volume matrix causing firmware metadata parsers to crash on some printers (notably Creality K2). -
Fix flushing dialog interaction and add Esc to close dialogs by @derrickwzb in OrcaSlicer/OrcaSlicer#12694 and OrcaSlicer/OrcaSlicer#12697
Fixed the flushing dialog being movable via trackpad overscrolling and added Escape key support to close dialogs. -
Warning for Hollow base pattern on non-tree supports by @valerii-bokhan in OrcaSlicer/OrcaSlicer#12710
Adds a warning when selecting "Hollow" base pattern for non-tree supports, informing that "Rectilinear" will be used instead. -
