ok so i have an irvision3dl camera and if i scroll the robot 10 mm in x+ or x- it gives me a 20 mm offset in the vision offset menu
but also it shows my positional data as moving 20 mm in the irvision menu after i snap and find.

You need to correctly set/calibrate your Z height.
-
Z height needs to be set to the distance from the offset frame to the part surface. If the grid is used as the offset frame then it is simply the part thickness.
-
As I experienced even if you calibrate it "good" it doesn't work well because you must mess something in calibration (I don't mean grid cal - I mean processing)
What I found out that you have in fourth tab in grid calibration something like focal distance or something like that, and there is automatic mode - for me I had to change parameters of it to match distance between camera and an object. I did it in 2D but i think it should be similarly in 3D -
There is an option for a single plane or 2 plane calibration. If you choose 2 plane then it should calculate the focal distance for you.
