zvila 0 Posted April 18, 2016 in UM2+ & Octopi: Rear Fan Issue UM2+ with Octopi: Rear Fan Issue After just a couple of attempts, I’ve managed to bring my UM2+ to work with OctoPrint on a Raspberry Pi. Everything works well: file transfer, printing, camera, remote controlling of the process… However, one thing I can’t bring to function: REAR FAN! The two fans directed downwards work properly, but the rear fan remains still through the whole printing procedure. Does anyone have the same issue and – even more importantly – a solution for that?

zvila 0 Posted April 25, 2016 in UM2+ & Octopi: Rear Fan Issue Problem "solved"! Actually it disappeared. After one week I decided to connect the OctoPi to my UM2+ again and now it works!? I did not change ANYTHING... IT-god works in mysterious ways... Share this post Link to post Share on other sites
