I am fighting a similar issue, but suspect that the cause is different.
I think you can check for square like this:
- true the wheel
- lower the universal support to the wheel and use it as a ruler to draw a line across your stone. It should be square
-clamp a ruler in se-77 so that it's against the edge
- make sure butt of the ruler follows the line you had drawn. Adjust as necessary
