I’m probably just going to keep my filament grouped but not segregated to a cabinet. I am pretty sure I’ll just be setting both cabinets to 10% and leaving them there. My reasoning is I’m already drying PLA and PETG to below 10% anyway and haven’t had any issues.
Down side will be more cycles on the regenerator by running at low humidity, but might not be too bad. Swapping spools back in from my AMS units will probably be carrying some amount of water into the cabinet depending on AMS desiccant.
