Like others have noted, this filament likes to be printed hot. The spool claims you can print it at 230C but it barely prints at that temp. Prints best for me at about 245C extruder, 75C bed, 40mm/s and fan at 35%. If you get way too much adhesion on the build plate, a light dusting of baby powder did the trick for me. A little more retraction than PLA, and I've been z-hopping the prints to avoid surface defects from travel moves on the first/last layer. Once I got that tuned in, this PETG prints excellent. Note - I actually had to upgrade my Maker Select Plus to an all-metal hotend before I could print this since anything above about 240C causes the stock hotend liner to break down. I should know since I destroyed the original hotend liner trying to get this filament to print well.
