Monitor and control Snapmaker 3D printers (U1 with Moonraker/Klipper). Use when checking print status, temperatures, progress, or controlling prints (pause/resume/cancel). Triggers on "printer", "3D print", "Snapmaker", "print status", "nozzle temp", "bed temp".
Control Snapmaker U1 printers via the Moonraker API.
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:

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

The U1 uses Moonraker REST API on port 80:

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 |
| 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.
