Filament dryer humidity. Help!
Hello so I just got a sovol sho2 filament dryer and so I have been drying for 3 hours and the humidity is stuck at 32% it doesn’t go down. It just stays that way and the room is 33% humidity what is wrong?
RE: Filament dryer humidity. Help!
Is the temperature in the dryer appropriate for the filament type? e.g. 60C for PLA
Is there a small hole to release the humidity to the outside somewhere? Some dryers have been reported to have this hole blocked (and don't mention it in their manuals).

Yes there is a hole and it is not blocked it is open. I have it set to 45c for pla.

Do you have another humidity sensor that you can put in the dryer to confirm that the built-in sensor is actually working?

Yes I did that. Both are the same.

You may happen to live in an area where the current drying is not powerful enough to drop it lower, because the ambient humidity is very high.
I suggest checking local weather station readings.
See my GitHub and printables.com for some 3d stuff that you may like.

I'm out of ideas - as long as there is a) heat in the chamber, and b) lots of airflow, and c) a small hole to let moisture escape, you should see a decrease in relative humidity.
