z probe is triggered but homing crashes head into plate (4 replies)

hello

my configuration is a Ender 3 with SKR1.4 mainboard and Marlin 2.0.7.2 and TMC2130 stepper drivers

seem unable to get the z-axis to home properly. Wanted to use the stall detection of the tmc2130 also for z-homing. For x and y homing it works as a charm. This did not work. I don't know why (have tried to up the speed of homing and changing the sensitivity settings). Then I tried a mechanical switch. Using M119 I can see that the switch gets triggered when I expect it too. Alas the homing still does not work.

What am I missing?

thanks.
