Does anyone happen to have the circuit diagrams or electrical drawings for the control gear in the back of the cabinet on a June 2014 PCB Engraver? It has a nextmove with USB, a z-axis driver, a chunky toroidal transformer and the custom Denford relay/power supply PCB. (See below)
Many Thanks,
Gillian

In getting it going, I found the IDC connector was not making good contact and the machine could not home the Z axis so would never complete the homing sequence. A new connector on the old cable and a little IPA on the pins worked wonders. Once the z-axis stepper driver received a good step signal, the machine could home and become ready.
