Well good news, I replaced one of the rectifiers and low an behold the 2 24vdc LEDs lit up but not the mill on one. But I still can't control the X,Y with the control panel. Also I'm probably doing something wrong when I try to push a design to the machine even thou the panel says start ready. But there is some bad news as well there are a couple semiconductors with cracks, would it be worth trying to replace them? Pics below.

Is there a way to test the contactor?

Also I figured out what the unconnected wires went to, went to a plug on the side rail under the machine. I'm guessing to plug the power supply in for the control panel. Thou the plug isn't a standard US AC outlet.
Martin Just out of curiosity what do you plan on doing with all the left over (original) parts? Other then the motors.
