I used a laser tracker with <.0002 accuracy in the 120 inches of travel on the cinci. I was able to compensate to <.001 for the full 120 inches travel of the X axis. EMC2 has bidirectional compensation so you can adjust for uneven ball screw/nut wear in both directions. This is linear compensation. Linear compensation is one part of true accuracy.
