Sorry, I didn't answer your question about fixing the grounding issue. I simply went into my 220V outlet housing and added a wire from the ground side of the outlet to the back of its case. This grounded the whole machine and I no longer was getting any voltage across from the enclosure to the gantry and bed.

I removed the wire last week thinking that might have been causing a ground loop and retested. Oddly, I no longer have voltage crossing between the two.
I'm guessing something else was causing it but I did tighten down every terminal I could see and remember and the problem has gone away.

Do you know what an out of warranty repair for blown G540 inputs will cost? Wonder if it’s just a component on the motherboard that can be replaced?

Hi,
The motherboard can be purchased if faulty and replaced, as can each of the four axis drives.

Grounding everything is important you should have one place in your cabinet that all Grounds are connected ( Star Ground ) this can be a stud or best a Ground Buss

So all Ground wires must go to the Ground Buss there is no chance of a Ground loop, your cabinet must be Grounded to the Ground Buss along with everything in your cabinet that has a Ground requirement
