File contents

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:

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

Quick Commands

Check Status

scripts/snapmaker.py status

Filament Info

scripts/snapmaker.py filament

Shows RFID tag data for each slot: material type, color (hex), temp ranges, and sensor status.

Monitor Print (Live)

scripts/snapmaker.py monitor

Print Control

scripts/snapmaker.py pause
scripts/snapmaker.py resume  
scripts/snapmaker.py cancel

Temperature

scripts/snapmaker.py temps

API Reference

The U1 uses Moonraker REST API on port 80:

Endpoint	Description
`/server/info`	Server status
`/printer/info`	Printer info
`/printer/objects/query?heater_bed&extruder&print_stats`	Status
`/printer/print/pause`	Pause print
`/printer/print/resume`	Resume print
`/printer/print/cancel`	Cancel print

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):

Field	Description
`VENDOR`	"Snapmaker" or "NONE" if no RFID
`MANUFACTURER`	e.g. "Polymaker"
`MAIN_TYPE`	Material: "PLA", "PETG", "ABS", etc.
`SUB_TYPE`	Variant: "SnapSpeed", "generic", etc.
`RGB_1`	Color as decimal int (convert: `#${(rgb>>16&0xFF).toString(16)}...`)
`ARGB_COLOR`	Color with alpha (decimal)
`WEIGHT`	Spool weight in grams
`HOTEND_MIN_TEMP` / `HOTEND_MAX_TEMP`	Nozzle temp range
`BED_TEMP`	Recommended bed temp
`OFFICIAL`	true if official Snapmaker filament

filament_motion_sensor e{0-3}_filament

Field	Description
`filament_detected`	Boolean - filament present in slot
`enabled`	Boolean - sensor active

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