Get the current status of the 3D printer

List files available on the 3D printer

Upload G-code content or a local G-code file path to the printer. With print=true the exact uploaded bytes are inspected first (every S/R heater target, tool changes, hardware and material ceilings), printer state is checked, and a human confirmation is requested before the print starts.

Start printing a G-code file already stored on the printer. The server downloads and inspects the exact file, then starts a uniquely named checked copy after printer-state checks and human confirmation. Printers whose API cannot download files (Repetier, Prusa, Creality) refuse; use upload_gcode with print=true instead.

Cancel the current print job

Set the temperature of a printer component. Temperature 0 switches a heater off and is never gated. Positive targets are validated before connecting, limited by independent hardware and material ceilings, require a ready printer and a human confirmation.

Extend the base of an STL file by a specified amount

Slice an STL or 3MF file to generate G-code or a sliced 3MF. For Bambu-compatible CLI slicing (bambustudio, orcaslicer-bambulab, or orcaslicer with bambu_model), the exact bambu_model/nozzle machine preset from the selected slicer installation is required, profile inheritance is resolved before the CLI runs, and the result must contain plate G-code. Failures stop with the slicer's exit status and output.

Slice an STL or 3MF with a named template from the local template registry (BAMBU_TEMPLATE_DIR). The template supplies process settings; the machine preset still comes from bambu_model and nozzle_diameter.

List saved slicing templates (.3mf, .json, .config) in the local template registry directory.

Copy a .3mf, .json, or .config file into the local template registry under a template name.

Inspect slicer settings in a 3MF template or JSON/config profile without slicing (layer height, infill, walls, supports, brim, bed, printer, filaments).

Report every heater target in a G-code file (S and R forms, tool-addressed, RepRapFirmware G10/M568 and Klipper SET_HEATER_TEMPERATURE). An expected temperature matches only when it equals the file's highest target. Read-only; printing tools enforce their own safety gate.

Process an STL file (extend base), slice it, and start printing through the same checked print gate as upload_gcode/print_3mf. Expected temperatures are enforced: a mismatch refuses before upload.

Apply a specific transformation to a selected section of an STL file

Generate an SVG visualization of an STL file from multiple angles

Print a 3MF file on a Bambu Lab printer. The exact selected plate is inspected (model, nozzle, bed type, materials, every heater target) and checked against a fresh MQTT report of the printer's identity, nozzle, state, errors and loaded filament, then a human confirmation is requested before upload and start.

Inspect a FULU OrcaSlicer-bambulab install, platform runtime payload, setup commands, and optionally probe the BambuNetwork bridge.

Advanced FULU bridge RPC for BambuNetwork diagnostics and development. Read-only methods are allowed by default. Agent/session setup methods require allow_mutating_method=true. Raw print methods, printer messages, file transfers and unknown methods are refused because they would bypass the print safety gate; use print_3mf for checked printing.

Merge vertices in an STL file that are closer than the specified tolerance.

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

Attempt to rotate the model so its largest flat face lies on the XY plane (Z=0).

Inspect Blender MCP configuration or connect and discover the remote server's tools. Lists tool names and summaries; pass tool_names for the full input schemas of the tools you will call. Connecting does not edit the scene; use get_scene_info through blender_mcp_call to check the Blender addon.

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.

Export named objects from the live Blender scene to a new, verified STL for slicing. Writes world-space geometry with modifiers applied, without changing the scene, selection, or mode, and reports triangle count and bounding-box dimensions from the written file. Use this after editing or modelling through blender_mcp_call; Blender MCP's own export_scene writes GLB/FBX only. Requires standard Blender MCP and a shared local filesystem.

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.
