Regarding other tips about PETG: make sure the filament is dry. Wet PETG will pull lots of strings, no matter how "good" you're tuning your retractions.
Is this just down to the humidity?
It happens faster with high humidity. But it will happen in drier air too. A dry box will keep PETG dry, but not necessarily dry it.
It's not uncommon to have PETG with problematic moisture content directly from the factory, even shrink wrapped with desiccant.
I print PETG from a dry box set to 55C. Even when my print is done and it sits for a weekend (rare), I keep the dryer on. If I have to swap a spool, it goes in a dry box that I keep below 20% RH. I also use a lot of cheaper PETG, though. It's my least favorite filament to print so far, but one of my favorite to make functional held objects since it's one of the densest polymers used in printing and feels heftier than most 3d printed objects.
Gotcha. I'm new to printing in general but the use-case here is a wearable helmet for a costume so seems like PETG is worth the hassle. Definitely getting a lot of stringyness at my current settings though so maybe some extra finegaling is in order.
I kinda live in a swamp tho so it's pretty humid at all times here, though the printer is in the same room as a dehumidifier lol.
