Thanks for the input guys.
It seems as if I haven't found the correct settings to use a stepper as a spindle.
I have tried different values in the MDI using "S*********"
I have played with every posible variable imaginable.
The best I can get is a heavy pulse to my stepper about once every half second.
I have set my steps per unit, velocity, out puts, I have played with spindle speeds etc.
Under setup - spindle setup - motor control - I changed to "PWM control" and my stepper started to turn, but only at one speed (slow) and the pulses where very harsh and heavy sounding.
I also got a reverse this time. But I think that "PWM control" if for servo motors.
I am so close, I just feel as if I am missing one step. My stepper works very well set up as an a-axis, just wish it would set up as well as a spindle.
