Hi all,
Just wanted to let anyone interested know there is an easy very low cost fix for the EP controller.
I just removed all the parts except the motor driver card and the power supply. Then connect a ribbon cable to the 20 pin conn. then wire the other end of the ribbon cable to the right terminals on a parallel port connector. You can then plug in you standard pc running Mach3 or others and run this machine directly.
Cost about $5 for the connector.
I spent a couple of days tracing the circuit on the driver card until I was able to figure the wiring out. No need to buy new drivers.
