# it will stop the z axis if it measure the distance is <=1.2mm while homing z to avoid crash into the bed. and then set the z value to the actual read distance value.
# it will not raise nozzle 1.2mm
position_endstop    : 1.2 # the triggered position, recommend value is 1~2.8
## The Sensor is attached to the board where the Z stepper are attached, too. 
collision_homing    : 0 # set it 1 to enable homing with nozzle collision sensing.
collision_calibrate : 0 # set it 1 to enable auto calibrate BDsensor with nozzle collision sensing.
QGL_Tilt_Probe      : 1 # set 1 to enable probe up and down when do quad_gantry_level    

#2. If I don´t use the Auto Calibration ... Do I need to set an Z offset so that the first layer can be printed without the nozzle touching the bed directly?
#Or is it position_endstop?
####  the only difference is that it will home z first with nozzle touching to find the 0 position if collision_calibrate:1

#If I set second-homing-speed to high (> 1.5) my stealtburner starts to bend because the head stops to late.
#### this depends on the mount height and the material of the bed plate,
