What do I need to do in order to get the green READY light to stay on and the servos moving.
You shouldn't have to do anything else but the step and direction pins.

It seems to me like you have a wiring issue causing the fault, and it's unrelated to any UCCNC setting.

Also, I noticed there's a UCCNC plugin for the C76. Do you have that installed and configured in UCCNC?

Here's a basic manual for getting the C76 working with UCCNC. Have you followed it?
