Machine thinks its somewhere else.

I have a new programmer trying to learn. Recently they located the sphere with the master, we only have one sphere in the system, The person then qualified their measuring probe. After running the base alignment which is a large Plane on the top for rotation in space as well as Z origin. a line on the left side of the part as the clocking feature, and a wide shallow cylinder  for X and Y, the operate then executes the program. Upon running the program as normal, the first feature in the base alignment, which is that large plane on the top fails to measure. It looks like the machine thinks the plane should be higher in Z, like search distance is a few millimeters off.

 

I have run into similar issues when there are two reference spheres in the system and the operator picks the wrong one, but I have never run into it with only one reference sphere in the systems. I'm going to run a different program to make sure they didn't do something in the programming that is holding a value, but while I am chasing this down, Does anyone have some preliminary thoughts?

Plane used in program has not zero value in Z,maybe?

 When the operator probed the line, did they do so in the right direction? Perhaps they probed in the wrong order, causing the alignment to flip.

Well good news is it is her program and not some bigger issue. I am going to have her redo her program. This is only for training, so there is no loss by starting over. I have a feeling she changed the base alignment several times, and calypso just wont let go of some previous value.
