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?
Along with ekZepp’s, check the z carriage as well- both the rail carriages for play and the lead screw for straightness.
I’ve seen similar happening on my bro’s ender, and he had to install a brace going up from the front of the printer to the top of the upright, but I’m not sure how rigid a mk2 is.
It does seem like one of the screws it touching the side of the stabilizer at the top, and the other is perfectly straight and isn’t, so I might need to look into that. Thanks for pointing me in the right direction.
