Hey folks,

I'm not sure what I'm doing wrong. I'm printing PETG (https://kingroon.com/collections/petg-filament?) on my Neptune 3 Plus. It's sort of like it starts (almost) ok, sticks to the plate just fine, then a few layers up it seems to almost have inconsistent extrusion (or maybe even trouble pulling the filament?) leading to holes, etc. till the model just falls apart. See linked photos for about where I give up each time.

I'm printing with Cura and 240C printing, 90C on the build plate. 45mm/s (I've gone down from 60mm/s). Retraction on, no z-hop. 60% fan, though I've tried it with 20% and 100% fan as well.

The filament is in a dryer at 55C. Funny enough I printed basically perfectly (without drying, straight out of the bag) with default settings the first time I printed. The second time and on, have had this problem... and have had it in the dryer.

Any ideas would be much appreciated. Thanks!

Edit: In case its useful, I'm printing this piece: https://file.io/D9jxYq4KOrL7 which is a small remix of a piece from https://www.printables.com/model/130507-bolt-action-pen-for-pilot-g2-cartridges
