BDsensor-m

The BD sensor is a distance sensor that can be used with a 3D printer to perform rapid bed leveling and adjust the Z-axis in real time.

Features​

  • Installation Guide
  • Replaces Z-axis endstop
  • No need to raise or lower the Z-axis during scanning, increasing print speed
  • XY movement scanning, allows for dense mesh bed probing

Connection​

  • Power: 5V
  • Firmware: Klipper/Marlin
  • Connection: Mainboard (BDsensor will use the mainboard's exp1 interface)
  • Heated Bed: Supports: Regular PEI, aluminum plate heated beds, and other metallic surface heated beds, does not support magnetically perforated heated beds or non-metallic surface heated beds

Precautions​

  • Klipper requires downloading Klipper and the latest BD-SENSOR-m patch, and reflashing the mainboard firmware
  • Keep the emergency stop within reach during debugging to avoid scratching the PEI
  • Recommended bed scanning speed is 200!
  • Z-axis homing speed should not exceed 5
