BDsensor-m

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

Features​

  • Installation introduction
  • Replace z-axis limit
  • No need to lift the z-axis during scanning, improving print speed
  • XY movement scanning, capable of dense mesh bed detection

Connection​

  • Power: 5V
  • Firmware: Klipper/Marlin
  • Connection: Mainboard (BDsensor will use the mainboard's exp1 interface)
  • Heatbed: Supported: Ordinary PEI, aluminum plate heatbed and other metal surface heatbeds, not supported: magnet-drilled heatbeds and non-metallic surface heatbeds

Precautions​

  • Klipper needs to download the latest BD-SENSOR-m patch and the Klipper firmware, and the mainboard firmware needs to be reflashed
  • During debugging, please place the emergency stop somewhere that can be triggered at any time to avoid scratching the PEI
  • Suggested bed scanning speed is 200!
  • Z-axis homing speed is not recommended to exceed 5
