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
