finally i've managed to mount the auto-calibration addon to my hpb.
If i start "Set nozzle height", the new nozzle moves to vertikal position, but it don't stop when he reaches the printerbed, he presses the printerbed down!.
At this point, i switched power-off.
Is this normal behaviour or will the 3d-printed tool broke?
I have done the following steps:
- Mounted and connected the add as shown in the video
- Changed the new firmware as shown in the video
- Uploaded the new firmware, it is shown as "Marlin 1.1.1" in the display
Can you tell me, what i have done wrong?
