What must be adjusted to correct out of round circles

Thanks! I am glad you sent the chart, as I really did not know what to do with the test. Will do the measurements tomorrow.

FWIW, I decided to re-calibrate using v 1.11, thinking there might be some improvements in the results. Went through the whole process, including the triangulation test cut. Then ran my circles test, with pretty much the same distortions… pretty much all perfect widths, with errors in the heights of 1/8” to 1/16”…

Connected with @Jon and @arnoldcp at Fully Calibrated but Oblong Circles
and chain pitch was discussed. Check it out and let me know what you think. I suspect that with the new calibration I will need to re-cut the Calibration test, correct?

Thanks!
