I’m retrofitting an older CNC router with a new control system. I’m using a UC 400 motion controller connected to a C11G breakout board that is connected to four 5056 drivers. Have communication with Mach3, all my outputs on the C11 are enabled with the green LED light illuminated…when I use Mach 3 to jog the system the corresponding output LEDs illuminate, but no motor movement! the motors are “holding” so they obviously are getting power. Drivers are connected properly, pins are set properly in Mach3, but can’t figure out what I’m missing. Motors were working fine with old control system. Any ideas?

Make sure Mach3 knows what port is feeding each signal.
Go to Config > Ports and Pins > Motor Outputs
Enable X/Y/Z/A as needed
Step Pin and Dir Pin numbers must match the actual pin numbers going from UC400 -> C11G -> 5056.
