Ball Screw Backlash- Centroid Acorn CNC retrofit

This week I'm back to working on the Dyna Myte - Centroid Acorn CNC retrofit. I investigate what I believe to be Y axis ball screw backlash on the DM2800. I calculate the stepper motor steps per revolution created by the Gecko G251X stepper drive and figure out the drive train turns ratio prior to doing some movement tests. My discoveries cause me to tear the Y axis apart for further investigation.
