Snapmaker Printer Control

Control Snapmaker U1 printers via the Moonraker API.

Configuration

Create a config file at ~/clawd/config/snapmaker.json:

{
  "ip": "192.168.x.x",
  "port": 80
}

Or use environment variables:

export SNAPMAKER_IP=192.168.x.x
export SNAPMAKER_PORT=80  # optional, defaults to 80

Config search order:

1. SNAPMAKER_IP environment variable (highest priority)
2. ~/clawd/config/snapmaker.json
3. ~/.config/clawdbot/snapmaker.json

API Reference

The U1 uses Moonraker REST API on port 80:

Status Response Fields

• print_stats.state: standby, printing, paused, complete, error
• print_stats.filename: Current file
• print_stats.print_duration: Seconds elapsed
• virtual_sdcard.progress: 0.0 to 1.0
• heater_bed.temperature / heater_bed.target: Bed temps
• extruder.temperature / extruder.target: Nozzle temps

Filament & Sensor Data

Query filament RFID and sensors:

/printer/objects/query?filament_detect&filament_motion_sensor%20e0_filament&filament_motion_sensor%20e1_filament&filament_motion_sensor%20e2_filament&filament_motion_sensor%20e3_filament

filament_detect.info[]

Array of 4 slots with RFID tag data (or defaults if no tag):

filament_motion_sensor e{0-3}_filament

Note: Slots can have filament_detected: true but VENDOR: NONE — this means third-party filament without RFID tag.
