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 is now available. You can install it with this command: flatpak install flathub com.orcaslicer.OrcaSlicer

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 https://github.com/OrcaSlicer/OrcaSlicer/pull/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 https://github.com/OrcaSlicer/OrcaSlicer/pull/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 https://github.com/OrcaSlicer/OrcaSlicer/pull/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 https://github.com/OrcaSlicer/OrcaSlicer/pull/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 https://github.com/OrcaSlicer/OrcaSlicer/pull/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 https://github.com/OrcaSlicer/OrcaSlicer/pull/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 https://github.com/OrcaSlicer/OrcaSlicer/pull/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 https://github.com/OrcaSlicer/OrcaSlicer/pull/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 https://github.com/OrcaSlicer/OrcaSlicer/pull/12860 Fixed a vulnerability where a crafted .3mf file 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 https://github.com/OrcaSlicer/OrcaSlicer/pull/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 https://github.com/OrcaSlicer/OrcaSlicer/pull/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 https://github.com/OrcaSlicer/OrcaSlicer/pull/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 https://github.com/OrcaSlicer/OrcaSlicer/pull/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 https://github.com/OrcaSlicer/OrcaSlicer/pull/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 https://github.com/OrcaSlicer/OrcaSlicer/pull/12705 and https://github.com/OrcaSlicer/OrcaSlicer/pull/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 https://github.com/OrcaSlicer/OrcaSlicer/pull/12739 Fixes #11715.

• Calibration dialog fixes by @yw4z in https://github.com/OrcaSlicer/OrcaSlicer/pull/12702 and https://github.com/OrcaSlicer/OrcaSlicer/pull/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 https://github.com/OrcaSlicer/OrcaSlicer/pull/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 https://github.com/OrcaSlicer/OrcaSlicer/pull/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 https://github.com/OrcaSlicer/OrcaSlicer/pull/12364 Fixed z-fighting where visibility markers for Wipe, Seam, and Retract/Unretract were obscured when overlaid on extrusion paths. Fixes #12100, #12556.

• Warning for Hollow base pattern on non-tree supports by @valerii-bokhan in https://github.com/OrcaSlicer/OrcaSlicer/pull/12710 Adds a warning when selecting "Hollow" base pattern for non-tree supports, informing that "Rectilinear" will be used instead.
