mark10970 0 Report post Posted June 29, 2013 in Extruder not heating My preassembled UM has been working well. Suddenly it won't heat, either under control of Cura or with the controller. Under Cura it seems to try for a minute or so, then the controller screen go blank then flickers on for a fraction of a second every 5 seconds or so. If I disconnect the power supply and run the controller from the USB, it continues to flicker the same way. If I then disconnect the USB and reconnect it, it goes back to normal. I have shut down and restaredt several times to no avail. Any ideas?? Thanks for any help. Share this post Link to post Share on other sites
