BDsensor is the first distance sensor that can work with 3D printer and do fast bed leveling and adjust z axis in real time. it can measure the bed distance at any point in real time without moving the z axis up and down.
Faster leveling, realtime compensation, high accuracy.
-
No need to do probe points before every print, it will be automatically compensated for based on actual distance in real time.
-
You can do bed mesh leveling like a normal proximity sensor but much faster with this BDsensor.
-
Easy manual bed level adjustment thanks to ability to display the live sensor distance measurement on your screen.
Sensor type: inductive, eddy, can only measure the metal plate.
Range: 4mm (for different metal the range should be different, the normal pei steel plate is 4mm, but aluminum is about 2mm)
- 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
- Support Can bus module
- Support high temperature chamber(120C) with the long cable probe BDsensorM.

- Auto z offset calibration.
- Overcome the temperature drift. The temperature drift will only change the z_offset, it will rise or low the whole bed mesh, but does not change the bed mesh with this BDsensor. that means the bed mesh is the same even with different temperature.
- Repeatability: +/-0.005mm
- No external hardware and easy to adjust
- For High temperature chamber up to 120C
- The lightest probe, 1.5g
