I do appreciate everyone's support with my previous problem. I am a bit further down the road to completion. However, I have struck another snag that is giving me headaches. When I send some G code to the controller, there is a high pitch sound from the stepper motors as though they are receiving pulses. However, there is no movement. I can control the stepper motors with a handheld controller and they move as they are supposed to. However, under computer control all I get is this high pitch noise from whatever stepper motor is supposed to be turning. Any ideas would be much appreciate.
