I need help. Out of nowhere, my A1 mini has started to give me ringing artifacts on curved surfaces only I printed a ringing test that was a 90° angle and no ringing was present. I have not changed the STL file or any parameters. I tensioned my belts as per the wiki and still no luck. I need some guidance as to where to look next.
I am printing in petg
The taller cylinder is from a month ago and the shorter one is the newer print

Check the Hotend 4 screws on the back side.
All 4 of the screws in the back are tight
Still getting the ringing
