Hi! I’m having an issue with my Creality Hi.

As you can see in the photos, I get a thick horizontal line/band on the surface of my prints. The strange thing is that it always appears at the same height, regardless of the model I print. After that point, the rest of the print continues normally.

I already replaced a part that Creality support had previously sent me because of another error, but this issue is still happening.

Has anyone experienced something similar with the Creality Hi?

Could this be related to the Z-axis, lead screws, alignment, or some kind of Z binding?

Any advice on what I should check would be appreciated.
