BIGTREETECH Relay V1.2 Automatic Shutdown Module – Smart Power Off After Printing
The BIGTREETECH Relay V1.2 (also known as BTT Power Shutdown Relay) is an upgraded automatic shutdown module designed to safely turn off your entire 3D printer once the print job is finished. It eliminates the need to leave your printer idling overnight, helping you save electricity and reduce fire risk.
Key Features & Benefits:
- Automatic Power Off — Detects print completion and cuts power to the printer automatically (via Marlin or Klipper macros)
- Short-Circuit Protection — Built-in detection on 5V/GND; immediately shuts down to protect the motherboard from damage or fire hazards
- Upgraded Design — Added small MCU for better stability and controllability compared to V1.0
- Easy Installation — Simple wiring with most BIGTREETECH motherboards (SKR series, Octopus, Manta, etc.)
- Wide Compatibility — Works with Ender 3, CR-10, Voron, RatRig, and other RepRap 3D printers running Marlin or Klipper firmware
- Energy Saving & Safety — Creates a fully automated, low-carbon 3D printing setup
