Hi,
At the very end of my teether.
I'm running mach3 using a gecko g251x board. Just the stepper motor is hooked up (it is free turning in both directions). In one direction, it runs smoothly and perfectly. In the other direction, it loses steps and vibrates but still turns. I've tried change every setting in Mach3 to no effect. Number of steps, velocity, acceleration, pulse width, basically everything checked. The driver test says the computer is good.
Any ideas hugely gratefully received. I've got paid projects mounting up with a direct correlation with stress levels.
Thanks.
