Hello ;
First did wire it all up right ? Double check all connections. Did you use the steps in the board manual ? , and when you apply power do motors lock up, can't move the shafts. Did you do all the Vref on all motors? Do you know what pins to tell Mach to run the motor on , step/dir ? Do you aready have motors mounted on a machine ? If so and motors power up , maybe there is something binding ? Let me know all the facts. It takes a little tweeking but it so worth it. Welcome to the world on CNC ............![]()
