Hi all,

I'm doing an experiment with a cabinet for filament with a small dehumidifier in it. I can get it to sit at 35%, but not much lower. I've sealed the cabinet with foam tape, and dried most of the filament first.

Are there any tricks to help improve performance of the mini dehumidifier? Maybe adding more heat to the cabinet?

The goal would be to use Home Assistant and the humidity sensor to turn things on and off as needed.

Thanks!

I am no expert, but in my own research for a previous task I had to deal with for work, most everything I saw said that getting below 30-35% for even a small room like a closet was going to be difficult without moving to heavy duty and expensive equipment. I don't know if there have been improvements in the technology since then (dehumidifiers have definitely gotten much smaller) but you start getting into issues were you are pulling moisture from the surrounding walls and items in the room.
I suspect in you situation you May be able to make some gains with heat, but I have to wonder if how hot you can go before you start seeing problems with the cabinet itself. I have seen cabinet delaminate just from being in hot garages, so I am not sure how hot you can get.

Yea, I was curious about "limits". I'd like to be stable at 30% vs 35%, then I can keep the petg and tpu in the dryers and everything else in the cabinet.

I have a couple of mini heaters I was going to build into chamber heaters for the SV08 Max, so I may stick one of them in there to see what happens.
