/diy/ - Do It Yourself

Been printing almost exclusivley with PETG for two years now. Skill issue on your part. Calibrate your extruder for it. The gears will bite into PETG diffrently than PLA, effectivley this means a diffrent drive gear diameter. You'll have to account for that. You should not overdo first layer squish as it will curl up behind the nozzle. A thick first layer is a good first layer for adhesion. Voarse textured PEI is a great printing surface for PETG. PETG will warp if you're using too much cooling. Leave part cooling off for the first 4-8 layers. However, for short <40 second layer times you will need to turn part cooling on. PETG is also notorious for stringing and will need calibrated retraction settings, Z-hop can also help. PETG does better when speeds are slowed down. I've printed sucessfully at 70-80mm/s on an Ender 5 Plus, just slow down for detailed parts. The main issue is my printer here and not the filament. A better printer could probably go faster. May need to turn up nozzle heat when printing fast. Normally i print between 230-240°C, 230°C has a less glossy and in my opinion better looking finish. Good luck anon.
