Good morning.

I recently acquired a 2016 PRS Alpha ATC. I was experimenting with a product that is symmetric. I ran it face up for one operation, then flipped it over for a secondary operation. I put some locating holes in the spoilboard to be able to locate it precisely. That's when I noticed that it did NOT line up with the cut-out lines from the previous operation.

I am assuming that this has to be the result of the table being out of square. However, when we unloaded the machine and leveled it, we also checked for square. What else can I do?
