Forca Slicer 0.1.0-alpha.2

Windows 64-bit · alpha · 2026-10-02 · based on OrcaSlicer's 2.5.0 development line

The second public alpha of Forca Slicer, a fork of OrcaSlicer. Still an alpha: it works on my printers, and I'd
like to hear how it does on yours — tell me what breaks,
or what works.

What's new since alpha.1

• Printer calibration in the Calibration Wizard: besides filaments, the wizard now calibrates your printer
  — Input Shaping, Cornering and VFA, using OrcaSlicer's own tests. Results go into your printer preset (with a
  backup and a restore button) or a new "(calibrated)" preset; Klipper users also get the printer.cfg lines.
• The Calibration Wizard is translated into all 22 of OrcaSlicer's languages (machine translations for now —
  corrections welcome).
• Forca Academy print journal (off by default, Preferences → Forca Academy): every print Forca sends gets a
  plain-files record (printer, presets, filaments, settings, a plate picture), File → Print Journal to mark how it
  went, and on Bambu printers Forca follows the print to its end, with optional camera pictures. Nothing is uploaded.
• Forca AI (experimental, off by default):
  • Control levels: Guarded (the default, as before) or Advanced, where the AI may save over your files and
    presets (Forca backs each one up first) and a print request opens the print dialog directly — you still press
    Send.
  • Print grants (Advanced only, Bambu printers): you can let the AI start prints itself, within limits you set —
    which printers, how many prints, for how long, the longest print, and optionally which files (with copies and
    a note). Every grant print needs a clear bed (your click, or, if you allow it, the AI's camera check), goes
    through the normal print dialog, and shows a 10-second countdown you can cancel.
• Fixes: the Max Volumetric Speed test's brim now holds on both sides of its wall (PCTG lifted before); Forca
  AI's G-code export runs your post-processing scripts; two Preferences tooltips are translated again; and more —
  see the changelog.

Before you install

• Keep your normal slicer. Forca uses its own settings folder and can copy your OrcaSlicer settings on first
  start (it never changes OrcaSlicer's).
• The build isn't code-signed yet: Windows SmartScreen will warn — More info → Run anyway.
• Check the preview and the first layers of anything that matters.

Known issues

See KNOWN_ISSUES.md. Most
important: Windows only; Forca can close shortly after sending a print to a Bambu printer (the print carries on —
it's in Bambu's network plugin); Forca AI is experimental.

Forca Slicer 0.1.0-alpha.1 — first public alpha

Windows 64-bit · alpha · 2026-09-26 · based on OrcaSlicer's 2.5.0 development line

This is the first public build of Forca Slicer, a fork of OrcaSlicer. It works on my printers; it has not been
tested on yours yet. That's what this release is for: please try it, and tell me what breaks.

What's in it

• Regional support interfaces: a different interface filament and a flush release gap only where you choose
  (placed box or painted area), on Grid, Snug, Tree and Organic supports.
• Calibration Wizard: Temperature → Max Volumetric Speed → Flow → Pressure Advance → Retraction → Shrinkage,
  guided, per filament, saved as one "(calibrated)" preset.
• Forca AI (experimental, off by default): an AI assistant can operate the slicer; it never overwrites your
  files, and it can only ask to print — you approve in Forca.
• Everything else is OrcaSlicer, merged up to late September 2026 — including Orca's experimental Design (CAD) tab,
  off until you enable it in Preferences.

Before you install

• Keep your normal slicer. Forca uses its own settings folder and can copy your OrcaSlicer settings on first
  start (it never changes OrcaSlicer's).
• The build isn't code-signed yet: Windows SmartScreen will warn — More info → Run anyway.
• Check the preview and the first layers of anything that matters.
