Most questions that get posted are the same question but slightly different situation. “Why does my first layer look bad”, “what is causing this weird noise”, “how do I diagnose this error”.
Your use case is interesting. I’ll remember it each time I see an update.
Re: dry. I’m convinced PLA doesn’t care about moisture. Watched a video of a guy that soaked a roll in a tub of water overnight, then printed off the roll with it still in the tub. Looked exactly the same as it did before the soak.
Mileage may vary of course but ever since then I’ve been leaving my PLA out and it’s never once given me trouble (the infused ones a little bit).
