This is the method I used to get my Shapeoko X rail orthogonal to the two Y rails. I've seen others use ratchet straps to force the Shapeoko base into a square shape by making the diagonal distances equidistant; but I think my method is easier, and will be more robust, as there are no internal stresses keeping the frame square. Just a few layers of aluminum foil shims installed on the 2" wide rail was all it took to take out gap I had across my 24 inches of travel.
