lucagiorcelli 0 Posted April 18, 2016 in Feeder goes crazy (iper rotation) when starting a print (edited) The video above shows the following strange behaviour on Ultimaker 2: Flow starts regularly. After few seconds the feeder goes in iper rotation. At the same time, the nozzle speed becomes very slow. The problem appeared two days ago (my Ultimaker is 4 months old). The problem persists with different gcodes. The problems disappears if I restart the Ultimaker. The problem comes back after 2/3 prints after restart. What is it?

52Cozens 1 Posted April 18, 2016 in Feeder goes crazy (iper rotation) when starting a print I would make sure the firmware and cura settings match. Make sure it is updated for the correct machine. Also I would clean the feeder and knurled wheel with a wire brush 1 Share this post Link to post Share on other sites
