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.
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.
