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 had horror stories about PETG only with a Vanadium or steel nozzle as it will tend to glob up when the temp is too low.
It did that to me during a print, knocked my PINDA sensor 1mm or so too high, and then leaked everywhere after it made the nozzle crash into the print and come a little bit out of the heat block and creating a gap.
