I’ve been having some serious issues getting PETG to print well, and I was wondering what settings other are using with success? I’m using a bedslinger in an enclosure and normally i print PLA with 200mm/s.
What are you doing for nozzle/bed temp, cooling fan, printing speeds etc? enclosed/open?
What is your printer capabilities normally for e.g. PLA?
PETG benefits a bit from drying. Though I don’t really get too excited unless I see stringing.
Adjust your retractions. Look at your retraction settings. You might need a bit longer and faster retraction. Or you might not want any retraction at all. YMMV per machine and filament and print. I like the scarf joint over straight retractions.
Wipe at the start and during a reaction.
Lower your print speeds a bit. I find running a bit slower helps with quality.
Lower your cooling fan speeds. PETG doesn’t play well in a hurricane. Even keeping it off completely has helped me on certain prints.
Use temp towers to choose the best temp for minimal stringing.
Notice I didn’t provide any numbers. That’s because every machine and the environment it works in is a rule unto itself. But your slicer will give you a baseline to start from. It’s up to you to figure out how to tune the settings you need to get the best results for your printer. There are no shortcuts here.
Yup, listen to this. I had problems with my PETG layers coming apart, especially the first few. I lowered the print and fan speed drastically. Fixed all the problems I had.
