BDsensor

The BD sensor is a distance sensor that can be used with a 3D printer, enabling fast bed leveling and Z-axis adjustment in real-time.

Features

• Replaces Z-axis endstop
• No need to raise the Z-axis during scanning, improving printing speed
• XY movement scanning, enabling dense mesh bed probing

Connection

• Power: 5V
• Firmware: Klipper/Marlin
• Connection: Tool board/Mainboard (BDsensor will use a servo port and an endstop port)
• Build plate: Standard PEI, aluminum plate, and other metal surface beds. Does not support magnetic drilling beds or non-metal surface beds

Precautions

• Klipper requires downloading the latest Klipper firmware along with the BD-SENSOR patch, and the mainboard firmware needs to be re-flashed
• Keep the emergency stop button within easy reach during debugging to avoid scratching the PEI surface
• Recommended scanning speed: 200 mm/s!
• Z-axis homing speed should not exceed 5 mm/s
