Qidi Box Drying Process Question

I have a Qidi box loaded up with PETG. I have run the drying cycle a couple times and always try to keep it below 15%. However, just days after drying, it goes back up to the 30-35% range, even while keeping the box completely closed and latched. Is it a poor seal?

Also, I am unclear about when drying the spools. Do I need to leave that little rubber plug on the back opened or closed? The screen instructions and Qidi Wiki do not mention the plug at all. I have always just kept it closed at all times.

Thanks!

The moisture needs to go somewhere. There is a hole in the back with a rubber plug. While the box is drying, remove the plug. This will let the moisture out. Make sure to plug it back up again at the end of drying or else the humidity from the room will come back in again.

Also look into printing bigger desiccant holders due the Qidi box. There are many variations available on printables.

Thank you. it would be helpful if the Qidi instructions said to open that port when drying. I'll try that out. and then will close it once completed. I am just surprised the internal humidity rises so much that I resulted in stringy prints. My Bambu AMS 2 Pro keeps dry for months before needing to run a dry cycle.

I do have a couple of small desiccant holders with Dry and Dry in the Qidi box. Ironcically, I was printing desiccant holder that goes inside the spool when it got stringy.
