Peculiar. Ryan, are you using a start alignment in the program by chance?

 I am not the only alignment that is set up in the program is the base.

I have a call into Zeiss the machine has since started doing other strange things and I fear I have sensor going out.

Understandable. One last suggestion (which you may have already tried) is power cycling the machine and your PC. Many an issue has been cleared from a hard reset for me over the years. Best of luck and hope you get your issue resolved soon.

When using the XTR, its very possible that a probe is qualified at the wrong rotation.  Check you stylus geometry screen to make sure everything is as you would expect it.  For example, a probe facing +x could have been qualified in the -Y direction.  I've had operators screw this up in the past.  

 

My second point:   There is absolutely nothing wrong with using circles for setting rotation.
