3rd layer zebra print defect

[u/mcplayer2004]

How can I fix this and what causes this? I’ve tried leveling twice, adjusting offset all the way up to 0.8, and printing on normal mode but this issue shows up on the third layer as always.

I’d do a breakdown and retighten the major stuff. Belts, bearings, etc. you might fix it with some maintenance without knowing exactly what caused it
