Get the current status of the Bambu Lab printer

Get the live AMS/external filament inventory from the printer over MQTT, including loaded/empty slot summary, resolved slicer profile paths, match confidence, and recommended load_filaments when the printer model is known.

Inspect a sliced 3MF and match its tray_info_idx filament requirements against the live AMS inventory. Does not upload or start a print.

List object IDs from a sliced 3MF plate. Use these IDs with skip_objects during a running print.

Extend the base of an STL file by a specified amount

Scale an STL file by specified factors

Rotate an STL file by specified angles (degrees)

Get detailed information about an STL file (bounding box, face count, dimensions)

List saved slicing templates from the local template registry directory.

Copy a 3MF, JSON, or config file into the local template registry and register it under a template name.

Inspect slicer settings from a saved 3MF template or a JSON/config slicer profile without slicing anything.

Slice an STL or 3MF using a named template from the local registry. This is a higher-level wrapper around slice_stl for template-based workflows.

Slice an STL or 3MF file using a slicer to generate printable G-code or sliced 3MF. IMPORTANT: bambu_model must be specified to ensure the slicer generates safe G-code for the correct printer.

List files stored on the Bambu Lab printer

Capture a single JPEG frame from the printer's chamber camera. TCP-on-6000 protocol (per OpenBambuAPI/video.md) — verified upstream for A1, A1 mini, P1S, P1P. X1/P2S use RTSP and are not yet supported. H2 series is undocumented and rejected with a clear error. Returns JPEG as base64; pass save_path to also write the bytes to disk.

Delete a file from the Bambu Lab printer's SD card via FTPS. Destructive: requires confirm:true. Restricted to cache/, timelapse/, and logs/ directories. Path traversal segments (..) are rejected.

Upload a G-code file to the Bambu Lab printer

Upload a local file to the Bambu Lab printer

Start printing a G-code file already on the Bambu Lab printer

Cancel the current print job on the Bambu Lab printer

Pause the current print job on the Bambu Lab printer (resumable via resume_print)

Resume a paused print job on the Bambu Lab printer

Clear HMS or print error state on the Bambu Lab printer using the clean_print_error MQTT command.

Set the active print speed mode: silent, standard, sport, or ludicrous.

Set H2/P2 airduct mode to cooling or heating.

Trigger a Bambu AMS RFID re-read for one AMS slot. This can move AMS filament; use only when the printer is idle and unloaded.

Set the temperature of a printer component (bed, nozzle)

Set a Bambu printer fan speed percentage using the printer's MQTT fan command

Set a Bambu printer light node mode using the printer's MQTT LED command

Skip specific object IDs during a running multi-object print using the printer's MQTT skip_objects command

Start or stop the AMS filament drying cycle. Available on AMS units with heating capability (AMS Pro / AMS-HT). Sends an ams_control MQTT command to the printer.

Print a 3MF file on a Bambu Lab printer. Auto-slices if the 3MF has no gcode. IMPORTANT: bambu_model must be specified to ensure safe printer operation.

Print a prepared two-part dog collar charm project using the fixed tray policy: inner/smaller object -> black on AMS 1 slot 1, outer/larger object -> white on AMS 2 slot 1.

Merge vertices in an STL file closer than the specified tolerance

Translate the model so its geometric center is at the origin (0,0,0)

Rotate the model so its largest flat face lies on the XY plane (Z=0)

Send STL-edit instructions to a Blender MCP bridge command for advanced model edits
