When you switch the Y and the A, you have to tell the controller to
change from linear to rotary. This should just be a scaling factor.
If not you can either scale the Y axis by PI*D in your drawing, or
draw it visually correct & scale the output by the same amount.

There are about 3 or 4 ways to accomplish the same thing, but in any
event you should have a round circle when you get done.
