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

/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.
