Ok, I gotcha. That makes sense. You are just saying that right now, with your filament always out, you don't have problems in a 50% humidity environment. If that's the case, that's good to know. I have AC so I don't really ever get much more than 50%. So, I maybe should not worry about it too much. I've printed on a roll for 3 or 4 days but then I always put it away. I haven't had any moisture problems that I know of. I need to do the test I mentioned earlier. Maybe I'll stop and do that tonight.
