Tools

Functions exposed to the LLM to take actions

NameDescription
start_sessionA

Start a private Xvfb display with openbox and launch OrcaSlicer on it.

Must be called before any other tool. Dismisses the first-run SSL and update dialogs. Returns a status string.

stop_sessionA

Terminate OrcaSlicer, openbox and Xvfb, freeing the display.

session_statusA

Report whether a session is running and list its top-level windows.

screenshotA

Capture the current OrcaSlicer screen and return it as a PNG image.

import_modelA

Import a model (STL/OBJ/3MF/STEP/AMF/SVG) into the running instance.

Delivers the file path to the already-running OrcaSlicer over the single-instance DBus channel (orca-slicer <path> with single-instance mode enabled in the app config), which routes it to Plater::load_files - no coordinate clicking. Waits until a top-level window title reflects the loaded model.

export_gcodeA

Slice the current plate and export G-code to an absolute path.

Sends a single orca-cmd:export:<path> command over the single-instance DBus channel. Inside OrcaSlicer this slices the current plate and writes the G-code straight to (Plater::export_gcode_to), bypassing the file dialog entirely. Completion is detected by the G-code file appearing on disk. Returns a summary parsed from the generated G-code header.

process_modelA

Convenience: import a model then slice + export G-code in one call.

print_gcodeA

Send a local .gcode file to the Creality printer and start printing it.

Reaches the printer's web UI through the docker container on the configured SSH host, bypassing the public oauth2-proxy gate, and drives the same two web actions a human would: upload the file, then start the print.

Set start=False to upload only and leave the file staged on the printer.

Configuration (environment variables): CREALITY_SSH_HOST (default t580), CREALITY_PROXY_CONTAINER (default creality-proxy), CREALITY_GCODE_DIR (default /usr/data/printer_data/gcodes).

clickA

Click at absolute screen coordinates (button 1=left, 3=right).

type_textC

Type literal text into the focused widget.

press_keyA

Send a key or chord in xdotool syntax (e.g. 'ctrl+i', 'Return', 'Escape').

zoomC

Zoom the 3D view. Positive steps zoom in, negative out, over (x,y).

When x/y are left at -1 the screen centre of the active session is used.

Prompts

Interactive templates invoked by user choice
