I only use my X1C occasionally. The AMS2 Pro remains closed for days, with additional ~200g of silica gel dried in oven and dried filaments inside. After an AMS’s drying cycle, the humidity is reduced considerably, but starts to increase regularly a bit less than 1% point per day. I built a wireless humidity logger for this purpose, and its readings match the printer’s value pretty well. Room humidity is 50-60%.
Do you observe a constant humidity rate with a closed, idle AMS 2 Pro for weeks, meaning that my AMS must be leaking somewhere? Or is this behavior normal?
FYI, I tried disconnecting the tube that goes from the AMS to the printer, closing its open end, to see if that was the source of the leak, but it didn’t change anything.
Here is a picture: One point equals one daily average value and the graph includes one drying cycle:
