I got an new CNC got it built and up and jogging, went and wired 5v fans on each of the Stepper motors, ran 5v and 12v up thru the cable chains, 5v for the Super PID and 12v for a later ad on (not connected) and now I cannot get it to move.

Originally when I turned on the Control box the motors made a noise like they set into gear, and all ran fine, now if I put my ear close to one of the motors is makes a low kind of Click noise and then silent and no movement.

I first thought it was the break out board, ordered another and it came in today put it in and no change.
this is the one I put in Amazon.com: Gikfun 5 axis CNC Breakout Board with optical coupler for Stepper Motor Driver MACH3 EK1206: Computers & Accessories
the original one looks the same but different color.

I checked my ports and pins, I checked volts in the printer port I have 4.3 on the pins set for the motors hitting the arrow keys in mach 3 either way gives the same volt.

Power is coming out the power supply..... I do not know how to check the steppers and the stepper drivers.

If I use the arrow keys in Mach3 the dro moves but the motors do not.

am I missing something?

could the ribbon cable go bad?

Thank you all in advance, this is a bit frustrating.
