Horizontal band with Cetus MKIII

Hi,

I am new to 3D printer and just started using my first 3D printer… Cetus MK3 :slight_smile:

I see a horizontal band in the test target that I printed (as shown in the attache picture). The band seems to be more apparent when the head prints from right to left vs left to right.

Has anyone seen similar issues? If so, how did you solve it?

Thanks in Advance

PS: I tried changing print quality or wall width and the issue seem to remain (it was less apparent with thinner wall, but is still there
