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.

    First things first, check your z offset petg doesn’t like being over squished and will lose adhesion because of it. The other thing you should do is ensure your surface is clean, depending on your surface a quick wash with soapy water and a brush is a good idea (some surfaces explicitly say not to do this, my buildtak surface called this out as something not to do), 99% IPA is decent at cleaning between prints but it’s a good idea to periodically degrease your surface.

    In my experience, adhesion issues with petg have almost always been due to residual oils (fingerprints) or bad 1st layer squish. I print in an enclosure, for me I absolutely require cooling, Prusa’s knowledge base is a good place to start as well.
