Been having issues with this Inland PETG. I've had so many failed prints. This 230C print temp and 80C build temp print was the least f***ed up print I had so far.

I also adjusted combing to Within Infill and retraction to 7mm at 60mms. All other settings should be default on Elegoo Cura N4P Normal settings

Some of the bridging is fine and there are sections that even look good but the rest are covered in blobs and stringing. The inside as it was printing was making noises and small pieces flew out as it was being scraped and stuff. The top layer shows a bit of what I mean.

I'm kind of new to this and can't seem to narrow down on what the issues are I found online. I've adjusted temps and only made it worse. I raised extruder a bit so that helped. I would like to make it looks as perfect as can be like my PLA prints.

Let me know your thoughts below, I'm happy to try them out.

Your retraction speed might be a little fast. 20-30mms is usually what I use. Only use the part cooling fan on the bridges. Speed can be a bit interesting. PETG is stringy. I typically print PETG pretty slow. 40-50 if I'm going for fine detail. Would probably increase the temp a bit too. That's a bunch of wild-ass guesses but it's where I'd start.

Alright I will lower retraction to 6mm at 30 mm/s.
