Get Bambu Lab cloud account profile

List all printers registered to the cloud account

Get printer status via cloud API (requires cloud cookies)

Sign a message with X.509 certificate for authenticated printer communication. Uses the extracted Bambu Connect certificate to bypass firmware auth restrictions.

Connect to a Bambu Lab printer via local MQTT over TLS. Required before any printer control commands.

Disconnect from the MQTT printer connection

Stop the current print job immediately

Pause the current print job

Resume a paused print job

Set print speed. Use a named profile (silent/standard/sport/ludicrous) or a percentage (1-166).

Send a single G-code command to the printer (e.g., "G28" for home). Dangerous commands are blocked for safety.

Start printing a file already on the printer SD card (uploaded via ftp_upload_file)

Request a full status push from the printer and return it. Includes temperatures, print progress, AMS state, fan speeds, and more. Note: pushall should not be called more than once every 5 minutes on P1P.

Return the last cached printer status without requesting a new push. Faster and lighter than printer_get_status — use this for frequent polling.

Get firmware and module version information for the connected printer

Skip specific objects during a multi-object print. Useful for excluding failed parts without stopping the entire print.

Change to a different AMS filament tray (0-3)

Unload the current filament from the extruder

Enable or disable camera recording on the printer

Enable or disable timelapse recording for the current print

Control the printer chamber or logo LED lights

Set the nozzle diameter (for printing profile selection)

Set nozzle or bed temperature via G-code. Validates against safe limits.

Upload a .gcode, .3mf, or .stl file to the printer SD card via FTPS (port 990). Use printer_print_file to start the print after upload.
