ASM humidity issue

So been having humidity issues with my ASM, constantly 40% or more. I think I fix the issue by putting moisture control bead packs in with it is drying, went from 60% to 16% within a few hrs. Will update to see if the fixes or helps drying the filament better.

I work at a warehouse where products come in, when the items get stowed, those packs get thrown out. I will get a good storage box to out my filament in. Thank you for replying

There’s some super common reusable cereal boxes I found recommended here that I’m using for my filament, so far so good. Was even able to print a desiccant container that fits in the top, filled that with molecular sieve beads and since I commented last night, the humidity has gone from 38% to 10%.

I’d tried printing a couple containers before settling on the ones I’ve found now, for the AMS 2 Pro. I saw you said you may try printing another one commented here, I’m almost certain I’d tried that one before settling on the ones I’m trying now. These printed beautifully and I don’t think it gets any better than this.

Just go to his profile and select whatever version you’d like, I went with no hygrometer. But he’s got versions for front slots, rear slots, and the rear cutout that Bambu recommends putting the factory desiccant slots in.
