Lines in prints - Lemmy.World

Just about all of my prints have these lines at around the same heights, and I can’t figure out why. I tried changing the nozzle, changing the layer height from 0.15 to 0.12, and changing the speed from 60mm to 40mm. All of these seemed to have helped a bit, yet they remain. I was thinking maybe as the prints get to a certain height, the shaking of the bed (Prusa MK2) caused the layers to be slightly offset perhaps. Anyone have any other ideas?

I was having this problem, combined with a confusing bed adhesion issue. My gantry needed to be releveled.

Thank you, checking this now. I made a change I found on a video and made a new post here.

How did you relevel your gantry? From what I see, you can loosen the two things I pointed to in my new post.

Question about horizontal lines (gantry) - Lemmy.World

I had previously posted [https://lemmy.world/post/10611049] about some horizontal line issues I’ve been having, and I tried a lot of the suggestions I got; Unfortunately the issue persists. I saw a video today, where someone mentioned that these [https://imgur.com/a/BFAjh9y] connections that are basically responsible for raising and lowering the printer head should be somewhat loose, and not tight (as I had them). Does anyone know if this is true? The video creator said that it is to allow for some ‘forgiveness’ between the two screws that drive the printer head up and down.

I have a different printer; it was a pretty involved process that required partial disassembly. I imagine this is very printer specific.
Gotcha, thank you!
