Hi Thanks again for your help. I now have power to stepper motors but they will not run, they sound stalled or trying to run to fast so do not rotate
Do you have any idea ??

Double check you have A+A-B+B- motor connections in the correct order on the driver. If incorrect you can get this happen due to dir conflict.

Which model numbers are the motors specifically.?.
What is actual machine?.

Most likely happening because your motor tuning in mach3 is set for the Gecko drives and these cheaper TB-based drives cannot handle the same tuning setup. Try backing off the velocity and Acceleration by 50% and try again. When you have it working stable then slowly increase them one at a time until they start to stall again then back off again by 10%.
