    Losing Alignment on Angle Change?

    Alright, here is my code. The first bit here is with A0B0. Just before the last move point it changes to A90B180.

    Code:
     DATUM_B    =AUTO/CYLINDER,SHOWALLPARAMS = NO,SHOWHITS = YES
            THEO/0,0,-0.58,0,0,-1,1.373

            MOVE/POINT,NORMAL,1,-2.5,1
    Everything is fine and dandy until that last move point. Instead of moving to 1,-2.5,1 it is moving to something more like 1,-3.5,-.2!

    I recalibrated my tips (std dev of .0001 and .0000), I re-ran the entire program with no change. I am going to try a shutdown/re-boot. Anyone got any ideas?

    Did you perhaps put in the movepoint before the tip change and then go back and put the tip change in? Have you tried deleting tip change and movepoint and then recreating them? Just a couple things to try.

      Yep, I tried deleting both the angle change and the move point following it.

        Well, shutdown/re-start didn't help either.

          Well, going back through the program line for line I found the problem. My probe is a 4X20mm. It is supposed to be a 4X20 with a 30mm extension! Problems don't show up until I rotated away from A0B0.

          Boy have I got egg on my face now. I even tried the scroll lock to see if that would fix the problem. TGIT!
