Having some issues with a program, I've got a work around, but some of the things I'm seeing has raised some questions. So I'm running an experiment. So far I've ran the same fixtured part without moving it 9 times. Any insight on why the demon is doing what it's doing in these 3 numbered issues? Thanks.

If I lock my Z axis travel, 6 out of 6 times I get good results between the 2 points and the program runs.

But if I don't lock the Z axis travel, 3 out of the 4 times the hit results make no sense at all. The Y & Z values should be within .5" of each other at absolute worst case scenario.

1st run, Point B4 has Y @ 8.799, Z @ -1.9582. Point B5 has [email protected] .8592, Z @ -7.5833

2nd run ok, Y values within .15" of each other

3rd run, Point B4 has Y @ -3.1692, Z @ -7.1652. Point B5 has [email protected] 5.3791, Z @ -2.4503

4th run, Point B4 has Y @ 7.6684, Z @ -1.3922. Point B5 has [email protected] .4793, Z @ -8.263

I reviewed the data ahead of this, and every time the vector of level plane is .999... in X and rotate line vector is .999... in Z, so nearly perpendicular to machine. So why would my results be so skewed in Y and Z when they should be reasonably close to each other?

Thanks

**1)**Part is nearly perpendicular to MCS. At this point in manual alignment, I've leveled to X+, Rotated to Z+, and translated to X & Z. The final 2 points establish the Y axis translation.If I lock my Z axis travel, 6 out of 6 times I get good results between the 2 points and the program runs.

**2)**2 out of 6 times it has skipped the incremental move to clear the part right after going in to DCC mode. Any ideas why?**3)**One time it created the plane below. All 3 of my points are nearly perfect X plus vector, with not much deviation in the X results. Yet the plane constructed from them is this skewed 3D monstrosity that would have crashed the head if I wasn't watching it once going into DCC. Not sure on how the math behind the plane creation works, but in my mind, if all 3 points have the same vector, than that's the vector that the plane is created on. Any insight?Thanks
