Hello.
I'm trying to create a program that can measure 24 equal parts in a fixture. I've created a
program that simply shifts the origin to measure the next part. The issue arises in the alignment,
where PC-DMIS compensates, causing me to measure the same part multiple times
instead of moving to the next one. For instance, if I apply an alignment offset in X +100,
the nominal values of auto features change. How can I prevent the alignment from altering nominal
values during execution?" I've pasted the program below. Does anybody know how
to fix this issue?
PART ALIGNMENT=GROUP/SHOWALLPARAMS=NO (Here lies 24 x and y alignment offset)
