Unfortunately the wiring is very simple in this machine. (It's just a small sign router.) There is a main control board, with a couple of daughter boards (one for coms the other is the main brain) the encoder cables are plugged into the main board, as are the limits, and some other misc IO. Then there are 3 ribbon cables one for each amp. That it. I've checked the integrity of the ribbons and they all seem fine. There isn't a bunch of individual wires anywhere that one could come loose and cause this. The amps only have 4 other wires 2 for the motors and 2 for the DC supply.

I would trace that specific signal as its likely a dc voltage, or lack of it at the amplifier. The fact that the error doesn't move when you swap amps around wants to tell me its in cabinet wiring, something shaken loose perhaps? Do you have any docs at all? A clue as to how old it actually is? > Todd Zuercher > P.
