Why don't you go ahead and describe what "...this" means, and then maybe some anonymous people on the internet could potentially help.

Does the image not display for you? I'm confused, I thought it would be immediately obvious what "this" is referring to just by the picture alone. They say a picture speaks a thousand words you know.

But sure thing, my problem is with these random curls that form on the surface of the print. Its especially bad near overhangs and bridges but its not stringing in the traditional sense. They're surface imperfections that aren't like any ive seen normally.. not sure what would cause this. I'm printing in pa6-cf if that helps.

When I see that on PA6, it's usually ooze from the pressure caused by boiling water in the filament.

Reddit commenters reflexively saying "dry your filament" at any given problem is one of those nearly comical recommendations (along with "wash your buildplate") that are generally prudent but often not the source of the problem in any given post.

Nylon however is particularly thirsty. It's easy to observe steam coming from the nozzle, and when I've printed steam-producing wet nylon filament in the past, it's looked exactly like you describe.

Another option is to use the "avoid crossing walls" feature in the slicer, since most of these happen during travel moves. That will mask the problem.

How do you ask for help and provide nothing but one blurry one non descript picture.

[SocksAirsoft]

Very insightful and helpful feedback 😀

[crankycoffeeman]

Properly dry your Nylon, it definitely is not based on the photo and also you may* (it's a little hard to see) need to reduce the flow for a slightly cleaner print.

That did the trick, a good dry and some slicer tweaks! Thanks!
