Never thought I would be posting a “How To” as I am probably the least computer savvy person here. I do like to figure out how things work. I will give a few thoughts.

This is what I had missed from the beginning.

> Hey Guys! Quick note to let you know we have an update to Simple Trace™ available [on the website](https://arcdroidcnc.com/pages/downloads) now (April 29) Should have got this one out sooner but it’s been a busy month. The main thing is a new X2 skew correction feature that an improve the stitching of your cuts. Basically it corrects the rotation of the ArcDroid with respect to the X2 rails down to the the 100/th of a degree. This can help to improve the stitching so you get minimal offset at the join reducing or removing the litt…

This will get you started and walk you through step by step, a lot like the calibration. I think what it is doing is correcting for the Arcdroid sitting on the X2 not exactly straight (manufacturing tolerances and whatever). It took me a bit to figure out what was going on. I thought my problem was the 2nd side was off on the Y axis. What it really was, was both halves were slightly rotated. Think of it as, say a 4-foot straight line is really 2 2-foot straight lines. If you were to rotate those 2 lines, say clockwise, where they meet in the middle, the #1 half would be low and the#2 half would be high, but they would be parallel. Like Andrew said in the above post, 0.1 degree would make a big difference.

If I am all wrong, please correct me.
