BDsensor

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​

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

Connection​

  • Power: 5V
  • Firmware: Klipper/Marlin
  • Connection: Toolboard/Mainboard (BDsensor will use a servo port and a limit switch port)
  • Hotbed: Ordinary PEI, aluminum plate hotbed and other metal surface hotbeds, does not support magnet-drilled hotbeds and non-metallic surface hotbeds

Precautions​

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