I am trying to get my Z axis dialed in and am having a problem. I had it at 1600 pulses/rev and got it moving the correct distance, but the problem is when i make small adjustments it moves .015 instead of .010 (and .007 instead of .005). So I can move it 6 inches up and it will be right on, but if I am at the work piece doing thousandths of inches, it is going 1.5X the amount I want. I tried on other pulses/rev settings also, from 800 up to 8000 and they all do 1.5X. I am using a smooth stepper and the KL8070D with a Nema 34 and the Ebay Z axis double ball screw. The X and Y work fine at 1600.
