So along the two sides that aren’t sticking properly, they were kind of bridged on there which explains the issues, however my second attempt printing with supports resulted in the same issues. I’m wondering why that is. I’m going to start printing with the fans off to see if that is the issue, everything else looks fine though. Let me know if you guys have any advice for better quality prints.
A brim will help but the biggest thing is not to use fans at all during the first several layers and very sparingly after that. Also be sure your printer isn’t getting hit by a draft from an air vent or open window. PETG warps badly like this from too much cooling/temperature variation.
How much % is sparingly? I’m thinking of turning them off the entire print. It’s a pretty large print.
Try with maybe 20-30% speeds after its printed several layers at 0%. You might even try your idea of zero fan the entire time. It’ll take trial and error so you may figure out a way to test on a smaller print so you don’t waste a bunch of filament.
I’m starting out with 0% first. However, I wonder if it will break my hardware as a device melting plastic at 245 C should have some cooling system or it will burn up right?
