It’s arguably the best part of the video

What could possibly go wrong?

Yeah, my oven is electric. Internet says 65C, which is conveniently as low as my oven goes

Silica gel has worked pretty well for me to keep a spool dry for a couple months, but I’ve never tried to dry a “wet” spool with it, so no idea. I’ve dried petg spools in the oven before, and it worked out. Can’t remember what temperature, but I’m sure that’s floating around on the internet somewhere.

Also the silica gel only keeps stuff dry if it’s dry itself. You can also heat that in the oven or a microwave to do that.

So yeah I’ve found petg (or at least the cheap stuff I’ve bought) to be kind of a pain. But if you’re almost neurotic about keeping it dry, you can get some super nice results. I only use it if I really want something to be clear

Looks like a filament moisture issue to me. PETG can get real weird unless it’s really dry. Temp is also a little low, but drying the filament will also fix the stringing issues you were seeing at 240
