Broken wire, maybe? Has it been working for the last few years and just stopped all of a sudden?

We do like photos so show us your shop, tools, projects, etc. whenever you're ready.

That sounds like it was generated because there was a loss of data transfer so could wiring problem but also could be computer related. If your computer or controller is a standalone unit and not connected to the internet and no updates or changes have been made to the system, software or firmware then it is probably in the wiring.

I would use a multimeter to check the wiring for a bad connection, broken wire, loose terminal connector. It could also be dirty corroded pins in some of the plugs or jacks so don't overlook that possibility.

Good luck with getting back up and running.
