That is a grounding/shielding issue, make sure the PC and the machine electronics and the cabinet are properly grounded.
Do not continue without fixing that, it usually adds another PC to the dump.

Add an input filter to the VFD. That is almost always needed, and they are not expensive.

(Look on eBay for "Rasmi", one of the cheaper manufacturers)

Found the problem. it was an earthing problem between the probe and the DIN relays. They were not using the same earth as the PDMX BOB. Surprised they worked at all.

Now to get tool touchoff to work.


Thanks for the help guys.
