RE: Stringing and Print Defects With Prusament PETG
I think the dryer is working properly. The grey PETG was dried for 6 hours at 60° C for 6 hours and was used right after with the dryer still on for the time it was printing. The dryer door was left ajar for the humidity to escape. However, I do notice that the printer door has been a little foggy lately so I suppose the printer chamber may be more moist than advised. Could that be the problem?

If the printer chamber is moist, it will make the filament rehydrate quicker.

Having water condensing on the door would be very unusual. Yes, the outside room (and hence the door) is cooler than the internal chamber temperature of the printer. So if the air inside the chamber is at a high relative humidity, water would condense on the inside of the door and also the metal frame parts. But why would the air in the chamber be so humid?! If it starts as room air, then gets heated up, its relative humidity should be lower than in the room.
When you wipe your hand across that "foggy" door, do you actually feel humidity? Or could it just be filament vapors which have settled on the door, in which case they should be solid and feel dry.

I noticed a "fogginess" develop from running the chamber hot. Wondering if it might be an aerosol from the lubricants.
