## Description

Slice 3D models into printer-ready G-code with OrcaSlicer, the open-source slicer with built-in profiles for most FDM printers (Prusa, Bambu Lab, Creality, Voron and more). Use when the user wants an `.stl`, `.3mf` or `.obj` model sliced for their printer, as a sliced `.gcode.3mf` or plain `.gcode`, headless with OrcaSlicer's command line or by opening the model in OrcaSlicer. Never contacts a printer.

Slice with OrcaSlicer, headless (below) or by opening the model in the
OrcaSlicer app for the user. The agent never contacts a printer: for a Bambu
Lab printer, hand the result to `$bambu-labs`; for any other printer, give the
user the `.gcode`.

## Install OrcaSlicer

- macOS: `brew install --cask orcaslicer`. The command line is
  `/Applications/OrcaSlicer.app/Contents/MacOS/OrcaSlicer`.
- Windows and Linux: install a release from
  https://github.com/OrcaSlicer/OrcaSlicer/releases. The command is
  `orca-slicer`; on Linux, run it from the AppImage or Flatpak.

Below, `<orca>` is that command.

## Slice headless

OrcaSlicer's command line (https://www.orcaslicer.com/wiki/cli/cli_mode) needs
complete presets: it doesn't fill in a preset's parent settings, and it slices
only with a process whose compatible printers name the printer.
`scripts/orca_presets.py` (Python 3, no dependencies) writes them from
OrcaSlicer's presets, searching the user's own first, then OrcaSlicer's
built-in profiles.

1. Find the user's printer, process and filament presets. Prefer the presets
   the user prints with; never invent one, since a wrong bed size or
   temperature can damage the printer.

   ```bash
   python scripts/orca_presets.py --list machine --match "MK4S"
   python scripts/orca_presets.py --list process --match "@MK4S 0.4"
   python scripts/orca_presets.py --list filament --match "PLA @MK4S"
   ```

2. Write the complete presets:

   ```bash
   python scripts/orca_presets.py --printer "Prusa MK4S 0.4 nozzle" \
     --process "0.20mm SPEED @MK4S 0.4" --filament "Prusa Generic PLA @MK4S" \
     --out presets
   ```

3. Slice. Give `--outputdir` an absolute path:
