Started checking my desiccant more carefully lately, and realized I was just leaving it in the storage boxes until it visually looked “done”. Turns out it absorbs moisture way faster than I assumed.
My setup: spools in a sealed cabinet with a built-in dehumidification system, sitting at ~25% RH. But I still use small desiccant packs in the boxes I keep near the printer for active spools.
How often do you guys regenerate yours? Oven? Dryer? Or do you just replace it?
