Also homing trouble - X homing runs into ALARM

[hmmueller]

I have limit switches, they are connected via an RC and there's an overvoltage diode protection, and they work like they should (I know because sometimes during jogging I run into them ;-)).
Homing is set up, with $23 directions for Z and X correctly set up (I'm not sure about Y) and standard speeds (50 and 10). I'm using UGS.
When I do $H, Z homing works as it should. But with X, the limit switches triggers an ALARM, and everything stops.
Any idea what I dont understand? Thanks!

It's hard to know without knowing your configuration.
You can try to enable this option to get some more clues.

If you are using master branch please redownloaded as I just noticed I left some options enabled that prevent non volatile storage from working properly thus your settings are not being saved.

Thanks for hint!

I only came around to a few tests yesterday. Actually, $H sometimes does work. It seems to me that it does not work if an axis is very near to a limit switch - then it starts moving in the homing direction and immediately says ALARM. Maybe this happens if the limit switch is triggered in the acceleration phase?.
When I jogged all axes to some distance from the limit switches (about 15 mm) and then did $H, homing did work.

I hope I find more time to check this out in the evening; I'll also post the precise µCNC version and the $$ values, if this is of any value.
