Hi

All 4 stepper motors stop suddenly working under Mach 3 on my main pc and even with my 2nd pc.

When I hit the x, y, z buttons on my pc Mach 3 is moving on the screen but the step motors are not working

As per attached picture, the rockcliff stepper driver card look powered, connections are good.

Do you have an idea of the problem and the solution

Thanks

Jack
