I purchased a couple of Sunlu dehydrators. The devices can only set temp and must be reset every 24 hours. It is pretty dry this time of year so I decided to learn how to use with these before spring came. I use humidity strips in the dehydrators and am always at 10% RH. I started with 50C. I noticed that my very pliable filament was gradually getting more brittle by the end of the roll. It never broke and the prints stayed good. I dropped the temp by 5C with each new roll. At 40C the filament stayed pliable through the full roll. I can't find much info on Ideal dehydration temp or methodology. Anyone have experience with this?
