Use the step calculator in Members Doc's to find the steps per unit which is in degrees. Here is the link:

Velocity, acceleration is by trial and error. start low and work your way up until it skips and then reduce by approx. 30%.
See the drive manual for recommended step and direction pulse settings.
You can use the axis calibration feature , Settings ALt 6 tab lower left corner of the screen, to check the steps per unit.

Hey Rich,
Thank you soon much.
The spreadsheet was awesome!
With a little tweaking on the machine after calculation, worked like a charm!
This forum is great, thanks again.
