It looks like your x and y axes are not orthogonal. You will have to move one end of one or the other to correct the problem. I designed a test cube just for this purpose and wrote a spreadsheet that calculates the necessary correction. You can download them here: [www.youmagine.com]
Essentially, the object is a 100 mm cube. You measure the lengths of the sides and the diagonals and enter that data into the spreadsheet and it tells you how much you have to move the axis to correct the error.

The math is just Pythagorean theorem and a little trigonometry- nothing beyond high school level.
The physical length of the axis is the length of that axis between the points that attach it to the machine's frame. For example, the x axis length of an i3 type design is the distance between the Z screws. In an i3 design it is a little difficult to adjust the x axis, so I suggest you adjust the y axis.
Most likely you're going to shift one end of the Y axis a couple mm. When you do so, loosen the attachments at both ends so that you don't produce a twisting or bending force by shifting one end. Shift whichever end you choose and then tighten both ends down again.
