Would someone who is successfully printing with PETG mind sharing their fff? I saw a post in 2015 but was wondering if things have evolved.

Much appreciated.

just recently bought a roll of eSun white PETG and it is really nice for mechanical part! With a proper calibrated starting height and extrusion multiplier it prints just like PLA . Sticks to the polymide tape really really well, almost too well. I use canned air upside down to freeze the parts off so as not to destroy the tape which I have done. The esun prints really nice at 245 with an 85 bed no fan.. Really like the stuff for mechanical stuff but is a bit stringy.

Use hairspray (Garnier Fructis #5) on the glass side of your build plate. PETG sticks just fine, and pops right off when you are done. If you flip the build plate, you may have to re-level. The thickness isn't uniform down to the level required for fussy prints. In my case, I used a micrometer and found that if I flip it side to side instead of end over end, it's close enough not to need re-zeroing.
