Hey guys. Bambu labs x1 carbon and Bambu PLA cf filament. I dried the filament before hand for 8 hours. The design I’m printing is one I made in fusion 360. The layer (which is shelled in 3mm) keeps printing with strings (filament not adhering to itself) but the rest of the print is perfect. It’s almost like there isn’t a final layer going over this portion (I think it’s a full layer actually). What can I do to fix this? I have no photos to show as I junked the print. Maybe it’s my model?
