Elegoo Phedca Rotary Test Doesn't Match Cut

Having some issues with my Elegoo Phedca Rotary attachment. I can set it up to make one full rotation in the rotary settings. When I hit the test button it goes around exactly once, then when I hit ok and go to outline a circle (at 4% power just to test it out) my cup spins around about 2.5 times and the laser would have cut a giant oval.

Where am I messing up? Is there somewhere I need to save or apply the settings from the rotary test screen?

What size is the circle?

This also smells like a mm/inch thing.

I’m not positive on the size since I can’t quite tell exactly how many turns the cup makes. I suppose I should set the travel speed a bit lower. That may be it.

When in standard x/y everything works just fine. The scale within lightburn corresponds to inches there

What size it it in software is what I meant; couldn’t tell from the video

Oh, about 3". Should be about a quarter of the circumference of the mug

Any advice?
