I've got a little issue with my Y axis, checking the guide rods on the extruder carriage I notice that it's closer on the left side to the front then on the right. I made a test print of a 80mm box with a 40mm square missing in the middle, I printed a 30mm square next to it. When I put the small square in the large hole I can see that in fact there is a difference as the small square isn't "square with all sides of the hole as I turn it around. I thought it would be as easy as just pulling on the belt on one side to make it move but it keeps sliding back to where it's offset again.
I thought this representation would be easier as it is very hard to take a picture showing the deviance.
So, if you look at the carriage holding the extruder you can see that the right side is more forward then the left side. The diagram is over exaggerated to show this. The guide rods for the X axis are parallel and as far as I can tell the guide rods on the Y axis are also parallel to each other. It almost seems like the belts are pulling the left side back a little?

It sounds like your right belt is tensioned higher than your left. Both sides need to be even. Have you tried tensioning them? Also, make sure both of your y-motors are working. If one is unplugged, or even worse, dead, then the other isn't strong enough to do the work.
