Or just toss it in the oven at a low temp for an hour or so. I’ve also turn my bed temp up high and put a spool on it with a box over it. Just cut some small holes in the too to allow humid air to come out. After an hour or so should be good to go. Assuming the issue is moist filament.
I want a filament dryer, but I’m too cheap, and don’t use my printer enough. :(
I want to start using it again, but I’ve been struggling to get the motivation to recalibrate and figure out all the optimal settings again.
