Y axis going 1/4 inch to much - anyone have this problem

I did a search to see if anyone had this problem, but i couldn’t find anything.
My problem is not that it is skipping, but on the Y axis its gaining 1/4 inch each 10 inches.
My carve is 50 inches long so its really throwing it out of wack.
I checked the wheels and the belt, which I would understand if it was skipping or traveling short, but its traveling to much.
Any Ideas?

It does it both in Easel and UGS.
Im stumped.
