I am running mach 3 connected to a machine with a Gecko g540. For limit switches I am using cnc router parts proximity swiches.

The machine has been up and running for about 18 months without any major issues. Homing and limit switches were working fine until about 3 weeks ago. At that time when I would home the machine the y axis would home properly but the x axis would move to the limit switch, trip the switch but not back off to a home position. I have checked the configuration and it has not changed.

Any idea what could cause this issue? I have an extra proximity switch that I could change out, but it seems that something changed elsewhere due to the fact that the limit switch will trip.

Thanks.

Thank you for the input.

This has been resolved.

I had another machine profile that I tested the "ref all home" button. That button worked properly so I loaded and copied the vbscript from that profile to the defective profile.

I am not really certain what was defective in the vbscript, because they had the same code, but copying the code did work.

Thanks!
