I calculated my backlaash originally by clamping a micrometer in the work clamp and moving the table back and fourth a number of times to see what the difference was from actual micrometer readings and the mach 3 dro.

I settled on y= .009 and x =.007.

When im making circle cuts, the circle is not round. How do I use the shape of the circle to determine fine tuning the backlash?
