Interesting filament experience.
Nothing groundbreaking but two days ago I printed hundreds of grams of yellow Prusament and it went great. Put it in one of my vacuum bags. Today I took it out to use up the last ~50g and got this.
Popped it in my dryer for 6 hours, tried again, and it printed perfectly again. I was surprised by the how quickly it went from “just fine” to “horror show”.
