OrcaSlicer 2.3.2

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

🌊 New Features & Improvements

• Configurable wipe tower type by @SoftFever in 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.

Wipe tower type setting

• Default values in tooltips for more option types by @valerii-bokhan in 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.

Default values in tooltips

• Improved MMU detection via Moonraker database by @ammmze in 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 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 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 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.

Accordion sidebar tabs

• Snapmaker esthetic filament sub-types by @gaaat98 in 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 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 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 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 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 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 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 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 github.com/OrcaSlicer/OrcaSlicer/pull/12705 ↗ and 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.
