My first batch of PETG HF black printed perfectly after 6 hours of drying at 65 with the SH02, I wonder if it needed drying at all.
My second batch - dried 8 hours, printed and found little pimples on the print, dried another 8, same issue, dried another 8 hours - looked ok in the beginning but same issue near the end of the roll.
Drying the inside of the roll is quite an issue!
I can tell somewhat how dry the roll is by looking at the humidity climb when I have the dryer closed, newly opened rolls will have the RH climb faster. Almost totally dry ones will settle at like 10%. But that doesn’t say much for the inside of the roll.
It seems like I need to dry 24h, and then dry between prints. For longer prints, have 2 spools and keep alternating them between the AMS and dryer…
