Looping not working right after a tool change and calibration??? What's wrong???

So, I tried to get my feet a little bit wet with looping, and I'm missing something or doing something wrong here and I can't figure it out. Basically, I've been running one part with a manual alignment and then 2 DCC alignments. That way I could open up the part number, do a manual alignment on the table where the part is, and after the first setup, I can just start the program where DCC begins so I can be more productive by just slapping a new part up there and running it DCC. I want to be able to run more than one part at once by just offsetting it in Y. I have 2 parts on the table, the original part location, and then after the first part is done probing, I ask it to move down 11.5" in Y and re-measure the second part. I have 2 probes that I'm using. It measure with a 4mmx20mm probe first, then changes to a 1mmx40 mm, calibrates, inspects some of the finer holes, then it switches back to the 4mmx20mm probe so the next part can be ready and it calibrates that probe as well. I'm running into a problem where basically It inspects the first part just fine with both probes on all the holes...it then inspects the second part with the 4mmx20mm probe just fine...but when it does a probe change to the 1mmx40mm probe, it tries to calibrate off my sphere...but the sphere has "moved" -11.5 inches in Y- , the same amount of space that the offsets for the loop is telling my program. I can't figure this out, because the 4mmx20 mm probe does just fine on the second part...it's the second probe for some reason that has trouble. I'm going crazy here! I'll post the code so y'all can see it. I will take any suggestions or hints. I know some people might not like how I'm running it? Basically it might be more efficient to run all of the first probe on BOTH parts, then change tools and probe both parts as well. Yes, the tool changing might be excessive. But...it shouldn't affect the program and do what it's doing to me??? This doesn't make sense.

OKAY!!! SO...I've *fixed* the problem. I say *fixed* because I didn't solve it using the exact parameters that I started out the problem with... I basically decided to just ditch "Single Probetip Calibrate" and instead inserted an auto-cal with my custom parameter sets (mainly just calibrating 0,0 only and the hit numbers and small things like that, the probe had like 7 angles originally) This was NOT an issue with looping, where my loop was, or anything to do with that. After I changed from single probetip cal to auto-cal everything lined up perfectly. There were a couple of variables that likely contributed to the original problems failure. First, the 2 spheres I drew for the single tip calibrate were NOT the same size and location. They were close, but by no means perfect. In fact, during the first tool change and calibrate, whenever the new tool would come down to make contact with the probe for the first touch, it wasn't even in the middle of the sphere, not even close!!! Also, during the second probe change, every now and then it would contact the probe too forcefully/ when it was done probing and trying to pull up it would just soft crash into the sphere. I am NOT the biggest fan of single probetip calibration now...I have it in a few other programs without looping, and I'm def going to go back for a closer look at those programs to make sure everything is working right, or I am just going to change it outright to avoid any future un-pleasantries.
