I am using TB6600 motor drivers and Mk4 Controller.
When wired up the motors lock as expected.
The TNG software is all working and green light in right hand corner with no cross.
When I try to jog nothing happens.
I have tried wiring the drivers both ways Anode and Cathode, no difference either way
I did notice the 5V is only 4.2v when using the Anode.
I have gone through settings toggling enable, invert etc.
I have no limits selected etc.
I do not believe the motor drivers are faulty as that would mean I have 3 faulty units.

Not sure if the board needs the 24V wired in as it powers up with USB. I tried disconnecting the 24V and it made no difference.
Please help, have I got a faulty controller card?
