Hi, sorry to post this again but I have zero confidence on this new forum-facebook-scroll-thingy. I been using x4 new fans on my umo+ connected to the fan pwm output. It was working great but yesterday the fans started to stay on after a print and I had to pwn off/on. They did seem fine. Also noticed that because My mistake the fans where at 40% but without moving for 20minutes so the power must have bounced back and burn something. Anyway at the end of the day the fans didn't start anymore
