BOB + MESA 7i92 limit switch error was created by prochj51

Hi,
I have NPN/NO proximity switch directly hooked to BOB (cnc interface board st-v3) connected to MESA 7i92.
It throws me an joint 0 limit switch error when I turn on the axis.

I check the signals with the halmeter and it seems to work properly. So I do not know what causes the error.

Any idea what I am missing?

Thanks
Jiri

You might have to invert the pin

Ok thanks, besides the inverted pin I had also other mistake in hal.

But I have another problem now. When I hit limit switch,
I am stuck in there and the override limit checkbox does not light up and
remains grey.

How can I activate it so I can get out from the stuck position?
