The basic question, if I want flexibility to dry multiple types of filament at the same time, would I be better off to get multiple 1 or 2-roll dryers instead of the Sunlu S4? I’m guessing with the S4, you can only dry one type at one time?
I.e., wanting to dry a roll of PLA and PETG, or even ABS, at the same time? It’s one big chamber in the S4, so if I set it for ABS then it would melt any PLA, correct?
The S4 just has one temperature setting, you would be better off getting 2 dryers.
The ABS setting might or might not melt PLA in a normal dryer, but my S4 has hot spots and will melt PLA spools on any setting. I haven’t printed a deflector for it yet, just been using my polydryers instead. I have 2 S4’s and have never opened the 2nd one.
Multiple dryers…I have 1 for each printer…it’s easier that way…JMO
EDIT: Once you have a dryer, print all your spools & filament clips in PETG.
I ended up getting a pair of Creality Space Pi Pluses. There was a seller on Amazon who sold a pair for $125 as a Black Friday deal, so even saved $5 over the S4 Black Friday sale price.
