Hello guys, I need all the help I can get.
My issue:
I calibrated the x and y to travel 5" and its spot on in both directions for both x and y. When I cut a round pocket it is Undersized by 0.120" I tried calibrating the motors to give me 1" accurate holes, but when I retest the motor calibration and instruct it to move 5", it travels to far, like 5.25" bad controller board? a setting? the Z axis is the only one that is accurate.
