So I have never seen this happen before and don’t understand…
I’ve been through teething issues of PETG in the past, namely stringing, but drying out thoroughly was always a pretty reliable solution whenever I started noticing print quality issues.
This time though, I put a roll of PETG that was working fine in the dryer overnight. I must stress I had no reason to, I was getting perfectly passable prints with no crazy stringing or anything, I guess my midnight brain just figured better dry preventatively…
Anywho, this spool was at ~55C for around 9 hours, and now it is stringing, underextruding, separating at layer lines, and in general just failing prints in various spaghetti monsters. Is it possible for PETG to be TOO dry?? The only variable here is putting the roll in a dryer, the printer still works with other filaments beautifully. Completely baffled…
