Well, if you feel like reading a fairly long topic that goes in a lot of directions, check out the following… > [@What must be adjusted to correct out of round circles](https://forums.maslowcnc.com/t/what-must-be-adjusted-to-correct-out-of-round-circles/3162): > > Have run several circle tests, and they are slightly out of round… In the center towards the top, 6" wide x 5 7/8 " high In the center towards the bottom, 6" wide x 5 15/16" high 30" either side the error narrows to 6" wide x 5 31/32" high What measurement errors cause this problem? FWIW, I used the machine to measure top beam length, and the result was 3004.57… used this for the temp sled calibration. When I calibrated using the new sled, I used a steel rule to measure the distance between… Towards the end there is a pretty detailed description of how my present calibration with the 12’ beam was obtained. The entire thread details multiple mods that led to a better understanding of how Maslow works. Keep us posted on your progress. --- _[View the full topic](https://forums.maslowcnc.com/t/distance-between-motors/7229)._
