RE: [CAD_CAM_EDM_DRO] What ratio to use for stepper motor drive?

On my X and Y axis of my SHoptask I am using 550 in/oz 200 step/rev motors.
They are driven in 1/2 step mode through a 2:1 reduction belt drive and are
turning some 5 tpi ball screws. This works out to 4000 steps per inch and my
maximum possible feed is about 80 ipm.
