Beginner Help with Multiple Alignments

I am measuring a mold cavity that is not supported with 3D CAD so I'm having to do more work manually on the machine. I did my manual and auto alignment with a plane and two dowel holes on the part. This alignment allowed me to do some measurements of the molding surface, and generate a line midpoint that I was going to use as my new XY zero, or A3. Like all new adventures, something has gone wrong. My Y position on A3 is out by about 45mm. I acknowledge that this is operator error but I cant find a mistake. Is there a limit to how many alignments you can do or some protocol that I have not discovered yet?

Thanks in advance, Glenn

Don't think so.
