Tools (46)

Read from the source code; the running server may differ. Descriptions are the server’s own words; hidden characters are shown as [U+…].

  • bambu_connect_import_file

    Open an existing G-code or sliced 3MF file in the signed-in Bambu Connect app through its official URL scheme. This is a cloud-mode handoff and does not start printing by itself.

  • bambu_network_bridge_status

    Inspect or probe the FULU OrcaSlicer-bambulab BambuNetwork bridge runtime used for cloud and restored BambuNetwork printing.

  • bambu_network_call

    Call a raw FULU OrcaSlicer-bambulab BambuNetwork bridge method, optionally with an initialized network agent injected into the payload.

  • blender_mcp_call

    Call a discovered tool on the configured Blender MCP server, preserving its full MCP content and errors. Discover tool schemas with blender_mcp_status first; execute_blender_code accepts Python code and user_prompt. Calls can modify the active Blender scene and are never automatically retried.

  • blender_mcp_edit_model

    Import, edit, and export a local STL through standard Blender MCP with verified output and existing scene objects preserved. Requires a shared local filesystem and Blender Object Mode. Also supports a separately configured legacy executable bridge.

  • blender_mcp_status

    Inspect Blender MCP configuration or connect and discover the remote server's tools and schemas. Connecting does not edit the scene; use get_scene_info through blender_mcp_call to check the Blender addon.

  • camera_snapshot

    Capture a single JPEG frame from the printer's chamber camera. A1/P1 use TCP-on-6000; X1/P2S/H2/X2D use RTSP via ffmpeg. Returns JPEG as base64; pass save_path to also write the bytes to disk.

  • cancel_print

    Cancel the current print job on the Bambu Lab printer

  • center_model

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

  • clear_hms_errors

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

  • delete_printer_file

    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.

  • extend_stl_base

    Extend the base of an STL file by a specified amount

  • get_printer_filaments

    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.

  • get_printer_status

    Get the current status of the Bambu Lab printer

  • get_slice_settings

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

Show 31 more tools
  • get_stl_info

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

  • inspect_print_fileread-only

    Inspect an exact private snapshot of a prepared sliced 3MF or textual G-code file and selected plate without contacting a printer. Returns versioned file-only evidence; no printer readiness or permission to dispatch is established. Does not auto-slice.

  • lay_flat

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

  • list_3mf_plate_objects

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

  • list_printer_files

    List files stored on the Bambu Lab printer

  • list_templates

    List saved slicing templates from the local template registry directory.

  • merge_vertices

    Merge vertices in an STL file closer than the specified tolerance

  • pause_print

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

  • print_3mf

    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_3mf_bambu_network

    Print a 3MF through FULU OrcaSlicer-bambulab's restored BambuNetwork path instead of the MCP LAN MQTT/FTPS path.

  • print_collar_charm

    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.

  • reread_ams_rfid

    Trigger a Bambu AMS RFID re-read for one AMS slot. X2D on macOS, or Linux with the native helper installed, uses the native official plug-in route. This can move AMS filament; use only when the printer is idle and unloaded.

  • resolve_3mf_ams_slots

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

  • resume_print

    Resume a paused print job on the Bambu Lab printer

  • rotate_stl

    Rotate an STL file by specified angles (degrees)

  • save_template

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

  • scale_stl

    Scale an STL file by specified factors

  • set_airduct_mode

    Set H2/P2 airduct mode to cooling or heating.

  • set_ams_drying

    Start or stop the AMS filament drying cycle. X2D on macOS, or Linux with the native helper installed, uses the native official plug-in route and supports AMS-HT id 128.

  • set_fan_speed

    Set a Bambu printer fan speed percentage. X2D on macOS, or Linux with the native helper installed, uses Bambu's networking plug-in without UI automation; other models use MQTT.

  • set_light

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

  • set_print_speed

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

  • set_temperature

    Set a checked bed or nozzle temperature. Positive heating requires matching fresh printer telemetry; nozzle heating also requires declared material. Zero turns the heater off.

  • skip_objects

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

  • slice_stl

    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.

  • slice_with_template

    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.

  • start_print

    Start printing a G-code file already on the Bambu Lab printer. Alias of start_print_job for upstream MCP compatibility.

  • start_print_job

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

  • upload_file

    Upload a local file to the Bambu Lab printer

  • upload_gcode

    Inspect a G-code file and upload a uniquely named copy without overwriting existing printer files.

  • x2d_native_control

    Read calibration results or update X2D AMS metadata/calibration selection through the installed plug-in. Raw motion, heating, task control, and safety-setting changes are rejected.
