Some of the filament that I plan to print with is hydroscopic. Even PETG gave me some trouble. I printed with a couple of spools over the course of a week and I left them on the printer spool holder. I think that was the issue. I might have been the worn out brass nozzle (I did a lot of glow in the dark printing for Halloween). I printed a lot of different things over the course of a month of 3D printer ownership so I can't really say one way or the other if this is necessary, useful, bs, etc, Ie it's not an endorsement or even a suggestion (I do like their vacuum sealing containers though).
This is the extremely high tech setup that I'm trying out Spare bedroom, empty monitor box, plywood for rocket fins for a base. Print Dryer Pro (bought from Matter Hackers), Prusa i3 MK3s, PETG filament in the dryer, holding at 65 degrees C. The spool of filament (two of them actually) was put in the dryer this morning. I ran it for 5 hours with no printer connection and then set it up like you see here. The print time is 5 hours and change so I set the timer to 6 hours. I'll switch to blue PETG once this one has successfully completed. So far so good...
