How to check if the dessicant needs to be replaced
When new, the desiccant will be a white powder. When the dessicant packs absorb moisture, they will gradually turn into a yellow paste. The desiccant needs to be changed when the entire pack is yellow because it loses the ability to keep the filament dry. We also recommend re-drying filament at that point. Please check if the desiccant needs to be replaced every 2 weeks. Learn more about the replacement of the dessicant on Bambu Lab Wiki.
