After inspecting a few parts the points on the CAD shift/move around on the CAD.

Hi,

Lately, this has been happening, and I don’t know why.

After inspecting a few parts, the points on the CAD shift/move around on the CAD. I am using an iterative alignment.
i Feel silly asking but has this happened to anyone, or why is it happening?

Apparently it is an alignment error. What is the "RGH_A3" alignment you have recalled??
When you apply Iterative alignment, use 3 points (your ITR_ point 1, 2, 3) as level, and 2 points (your ITR_point 5, 6) as rotation, and 1 point (your ITR_point 4).

Hi, Thank you.

The whole program didn't fit, so I only inter the final alignment. Which, most of the time, is the same as the rough alignment.

Yes, that is how I am using 3,2,1 Iterative alignment.

"RGH_A3" is a Rough alignment. First actual alignment for the machine to find part. The final alignment is A1. I even changed the final alignment from recalling "RGH_A3" to startup. Still the same issue.
