With those interlocks tested, and confirmed good. I would check the end-of-travel safety switches next. It may think that the head is at the end of it's travel.

I don't know your machine, but on mine the interlock is the large access door. It's done so that you cannot open the cover while running, but it also checks for a closed door at startup due to head homing sequence. Yours may be similar in that it won

It's been a long time but one thing I remember from those machines that about 50% of the time the error codes were a wild goose chase. At this point forget what the error code says. Can you move the head? Have you checked the servo cards? Is there

My company manufactures a board for a heavy duty automotive application. One of the through hole parts on the board dissipates enough heat that it requires high temp solder. Does anyone know of or have experience with a high quality selective solde
