A spool of PETG that used to print cleanly has started stringing more. It has been sitting on the printer for a while and I can hear the occasional tiny pop during extrusion.
My first instinct is to dry the spool before touching retraction, temperature or travel settings. Otherwise I could spend an hour tuning around wet filament and then have to undo it.
Is that a reasonable troubleshooting order, or are the popping sounds not as diagnostic as I think?
