I know myself and a couple of other people are suffering from an erratic chamber fan since the last update. I don’t know if it was the printer firmware or studio that did it, but my chamber fan is fluctuating all over the place during prints, 30, 40, 50% then bounces up to 100% every now and then, then bounces down to 70, 80%. It’s very very annoying, nearly 3 weeks now and nothing seems to be getting done about it.
