2/3 times your steps unit.

so if I am understanding this correct it should be like
DistanceTravled  = 3  Steps unit = 1800
 DroDistance  = 2
x = DistanceTravled * Steps unit
new steps unit = DroDistance  / x

Thanks gary

hi there are a few ways to do this. the best and most accurate is the way in the manual complete calculation ie ball screw pulleys motor ect then check with a Gage block or dial indicator. you could just plug in a different number up or down until 1" on dro = 1" traveled this isnt the most accurate but depending upon what machine you are running i am sure it has been done that way before.
