I found this while searching for the elusive perfect calibration for my PETG.I seem to get 1:3 good prints. Really weird. Biggest issue is collection on the nozzle. Found http://forum.makergear.com/viewtopic.php?f=11&t=2593 and thought others might find it useful.
Thanks! I just got a spool of PETG in red and I’m hoping to give it a try soon. That article looked very helpful.
Thanks for sharing Great post.
