Real-Time Measurement Eddy Current Distance Sensor BD Sensor is a distance sensor compatible with various 3D Printer firmware able to do fast bed leveling and z-axis adjustment in real time without needing to move and down on the measurement axis for a distance reading on any conductive surface. Your Toolhead Unstuck from the Past: Equipped with active compensation, BD Sensor doesn't need to wait for a bed mesh before every prints for accurate Z-offset calibration, it simply adjusts to the proper distance in real-time. Still, it serves your need for flexibility--allowing for lightning fast meshing if you so choose. Headache-free Tramming: Manual bed leveling is made easier than ever with live distance reading right to your screen. No more guess-and-check. Hardware It can connect to most motherboards or GPIOs on the RaspberryPi Easy to install: small and light; can be installed anywhere, even surrounding metal above CAN bus Supported High Temperature Ready (120C Rated) More info Bed leveling sensor | Hackaday.io bd sensor (eddy bed level) | Wiki markniu/Bed_Distance_sensor: Auto bed level with High resolution distance sensor BDsensor M · markniu/Bed_Distance_sensor Wiki
