OrcaSlicer 2.5.0 is out with Python plugins and color mixing
The stable OrcaSlicer 2.5.0 release adds Python plugins, color mixing from loaded filaments, belt printer support and more.
OrcaSlicer 2.5.0 is now available as a stable release. It is marked “Latest” on the project’s GitHub releases page and is dated November 7. If you slice with Orca, especially on a multi-color, multi-toolhead or belt printer, this is a big update to read through before you install.
The release notes say 2.5.0 rolls up the changes from the earlier alpha, beta and release candidate builds. The main additions are:
- Python plugins, with a Permissions tab that controls what each plugin can access.
- Color mixing, which lets you blend new colors from the filaments you have loaded.
- Belt printer support and texture displacement for adding surface texture to models.
- Multi-part printing on IDEX and IQEX printers.
- Toolhead collision volumes, which the notes say keep Arrange, brims and travel moves clear of obstacles.
- An experimental Design tab for parametric parts.
On the printer side, the notes list support for the Bambu Lab H2C and A2L, plus mixed nozzle sizes on the H2D and X2D. They also mention smarter travel planning, faster startup, slicing and export, a new Speed Dial, Precise Seam modifiers, new infill options and hundreds of bug fixes.
The notes describe the Design tab as experimental, so read the details before relying on it. The full list of changes and the downloads are on the project’s GitHub release page.
