In this video I find out the error that the ball screw of my CNC Router has and apply a pitch compensation in the software to improve the accuracy. The first step is to calibrate the linear glass scale to the DRO. For this I use a 100mm gauge block. Next I drive the axis a known distance, 10mm to start with and compare the DRO values. Unfortunately my C7 Ball Screw is not within the manufacturers tolerance. Next I use the EDING CNC Software to apply a pitch compensation to the Ball Screw Error. I am happy with the result, as I am able to improve the error from 0.15mm down to 0.02mm.
