Home Axis - Changing Mid Cut

1

Hey all, we currently are having difficulties with our machines resetting its home right in the middle of a cut. Or as I am calling it “bump stopping/freezing”. I believe this might be a communication error from the computer to the cnc computer.

I have tried the following:
-updated to the newest Mach4 and ran SCU-Application to maximize the communication
-replaced ethernet cables to the machines
-replaced x-axis motors and spindles
-reached out to avid support
-checked all cables going into the machine and the motors

Any advise would be greatly appreciated!

“Resetting its home” and “bump stopping/freezing” sound like two different things to me. Can you describe what symptoms you’re seeing? Is there a tripped limit switch while it’s in the middle of the table? Do the machine coordinate values jump, and if so, which axes and how much? Is something physical getting jammed?

Also, welcome to the forum.
