Nozzle Collision sensing + Bed scan = BDsensor , Contact Probe
Nozzle Collision sensing is a new feature after bed scanner for BDsensor that can work like a strain gauge while homing.
Auto calibrate: It can find the 0 position itself while homing,so no need to calibrate the z_offset with paper, it can also calibrate the BDsensor automatically
