I was printing PLA, it looks ok up to a certain height (although it was warping slightly), but then it becomes ugly. I will do a test print of the same height, butaybe you already have an idea.

Looks like a partial clogged nozzle to me.

Just happened to happen at that height. If I'm right it should Start at the bottom on the next print as well.

Cold pull should be the solution.

Thanks, maybe it was just tangled filament ๐Ÿค”, but I will do a cold pull anyways.

Maybe something got stuck in the nozzle, partly clogging it. Try cleaning it. A trick I often use is to start the nozzle preheating and then yank the filament out of it as soon as it becomes warm enough for that to be possible, that usually pulls whatever crud was stuck in the nozzle out along with it.

Thank you, I will give that a try.

White my test print from afterwards (after unspooling the last two meters from my first self rolled spool ๐Ÿ˜…), grey a print from a few days ago.

Depending on your printer the z axis lead screw might need cleaning and lubrication. I would get this on my ender 5 plus occasionally at a given height if the lead screw needed cleaned.

Looks like a clog, could be caused by too much retraction, too high temp combined with too low print speeds resulting with the filament being cooked inside the nozzle.
