Hey guys, somewhat new to 3d printing with PETG.
I had a few fairly decent prints about a month ago (first pic), albeit a bit hairy.
Now, my prints are turning out terrible with the same settings (next three pics).
Could my filament have absorbed moisture? My box claims to be airtight, though some rice I had in their previously did go bad.
The weird thing is that all the prints have decent initial layers.
Also, these last three pics were at least 12+ hours of printing, overnight.
Thanks for all your help!
