Thanks for the reply. I checked all with M119 and all homing sensors say open and triggered when they should. But just to be sure, I am hooking up a mechanical end switch (identical to the X and Y sensors) tomorrow, to temporarely replace the inductive sensor. If that does not fix it, I am replacing the RAMPS and Mega. I did notice today, while replacing the TMC2130 with A4988, the Z driver came off the board a lot easier than the others (bad contacts??) and the capacitor soldered on the RAMPS underneath the Z driver is positioned slightly off in comparisson to the ones under the other drivers. Weird. The complete sensor set-up worked before with the MKS board I used (which s**ked for other reasons).
Cheers,
Hugo
