I’ve seen in your hose thread that you have a horizontal frame, so that’s similar to my setup. I also have a small dimensional difference between x and y. Could you please measure:
- the dimensions of the square (x and y)
- the small and large diameter of the circle
- are the small and large diameter of the circle aligned with x or y, or is the oval rotated? In the picture it seems to be aligned with an axis, correct?
