I have been forced to do an almost rebuilt of the ormerd2 due to cracks on the z axis plastics and supply + duet failure. Now I experience something I either did see in my first built or I totally forgot about. When homing the head crashes against the z axis and keeps pushing. Occasionally it will calibrate in the white spot nearby before crashing against the axis. Because I have a new duet, I am back to latest RRP firmware and not dc42 yet.

Are you using orthogonal compensation?
I experienced similar problems, found there was something screwy with the homing.........I would be interested to know the results of this test
1) from startup home the X and Y axes in the order of XY and note the XY=0 position, if you haev calipers maybe measure the axes positions from a fixed point
2) turn off machine and repeat but in order YX
3) is there a visible or measurable difference between the two home positions?
4) remove the orthogonal compensation from your Config file and try again

While homing works, the Z0 is now almost 2cm too high ....
