@gloomyandy Update is done and I played a bit with the parameters but the homing is no very unreliable. Sometimes it works, sometimes not, sometimes to early.
M915 P1:2 S1 R1 F0 H10
ok
G1 H4 X260 F4000
Warning: Driver 1 stalled at Z height 0.00
Warning: Driver 2 stalled at Z height 0.00
I changed the S on M915 and H10 to lower and higher values. But nothing changes it really. And it looks to me like the stepper try to drive the toolhead very long above the physical limit.
I test with: (plus some variants.)

I played with faster movements to, up to F10000. And the steppers skip steps for about 200ms till the stall message appears in the console. Should that be the case?
Any idea in which direction I should go? I reduced the S on M569 but this triggers the detection instantly, and I can not go below 60% of the current, that makes the stepper not to move at all anymore.
Cheers, Chriss
