I’ve heard (and seem) many a horror story about PETG and was ready for hours of troubleshooting. Generic PETG settings in Prusaslicer and honestly this print couldn’t be much better! There’s a few layer inconsistencies, but those should be pretty trivial to fix after I get a temp tower done.
Printed on an Elegoo Neptune 3 Pro running Klipper using Overture PETG
I think most of the horror stories are from people printing way too fast and too low
Many people print with too small z-offset because “that’s when it sticks”. you can get away with it in pla but petg will just become a mess
I admit to leveling a little low with PETG on my i3, but not grossly so. I also printed “fast” (for am i3 at least). I still found PETG pretty easy to print, until I got to larger prints and had some warping until I figured out how to deal with that
I’m glad that I experienced PETG and happy I didn’t have to struggle too much. It did give me some troubleshooting tools that I’m putting to use on my 350mm build as I dip a toe into ASA.
