I don't have an AMS, but seldom find the need to print from my filament dryer. Unless I'm doing nylon, TPU or polycarbonate I almost never print from the dryer.

I used to dry before every print but got lazy and only dry my PLA every month or two or if it's causing issues. PETG is a bit more problematic but unless you are doing a bunch of fine details or multiple parts where the nozzle rapids all over the build plate the stringing is minimal.

If you get into engineering/specialty filament I'd definitely recommend a good dryer that can maintain a minimum of 70C.

I've been watching this thread and am surprised that no one has mentioned the cool ammo boxes that you can print for cheap.

I have a P2S with AMS2 pro

I have only printed PLA

I never dry PLA. No reason to. I dry PETG when I first get it, toss it in the box, then maybe dry again 6 months later. If a print is stringing I'll dry it again. PETG absorbs moisture but it's not a kitchen sponge. It takes a while and needs to be constantly exposed to a humid environment.

I normally dry a brand new roll of PLA and never again. Received too many that were stringy or bad adhesion from being too wet.
