Solved Mesa 7i76 Endstop connection

So far, I had a mach 3 board running on my 3 axis milling machine and now wanted to upgrade with a 7i25 & 7i76 plug & go kit.

I had mechanical NC limit switches and would like to continue using them.

But unfortunately I do not get these to run.

To narrow down the error I try the construction only with one limit switch.
E-Stop on Input 4 works. If i move E-Stop to Input 0 E-Stop works too. If I move X-Limit to input 4 I become a error.

If i invert the limit-switch the error comes by open the switch.

Today I test one PNP switch, but I have the same issue...



Can someone help me?

For PNP or NC (Normally Closed) limit/home switches you must connect the
hm2_5i25.0.7i76.0.0.input-XX-not limit/home pin to motions limit/home pins
This is not in question.

If you get an error, this means that something else about homing is not setup properly. I would suggest reading the linuxCNC documentation on homing:
