"""Manufacturing equipment control with conversational responses.
Provides unified control over 3D printers, CNC machines, and laser cutters
with rich conversational responses for natural AI interaction. Supports
complete manufacturing workflows from file upload to finished product.
PORTMANTEAU PATTERN RATIONALE:
Instead of creating separate tools for each device type and operation, this tool
consolidates manufacturing operations into a single interface. This design:
- Prevents tool explosion (9+ tools -> 1 tool) while maintaining full functionality
- Enables consistent manufacturing workflow across different device types
- Provides unified error handling and safety protocols
- Supports conversational AI interaction with rich response formats
- Follows FastMCP 2.13+ best practices for feature-rich MCP servers
SUPPORTED OPERATIONS:
- 3D Printers: Print control, monitoring, maintenance (OctoPrint/Moonraker)
- CNC Machines: Milling, drilling, cutting operations
- Laser Cutters: Vector cutting, engraving, material processing
Args:
device_id: Unique identifier for the manufacturing device
(e.g., "printer_01", "cnc_mill_01", "laser_pro_01")
device_type: Type of manufacturing equipment. MUST be one of:
- "3d_printer": FDM/FFF 3D printers (OctoPrint, Moonraker, Repetier)
- "cnc_machine": CNC milling/drilling machines
