Glamdring 1 Posted October 27, 2016 in Side fans and extrusion stopped working I'm using the UM2, the printer stopped extruding entirely, it isn't blocked, and at the same time or close to it both side fans stopped working. Does anyone have any ideas on how to fix this or even how the two issues may be related? thanks! Share this post Link to post Share on other sites
neotko 1,356 Posted October 28, 2016 in Side fans and extrusion stopped working (edited) Suddenly stopped? Does it wirk with ither gcode? It doesn't restart? Always happens? One of the cause for it to stop printing could be a sudden micro drop on the electrical supply from the house/workplace. I had once something like that but was because the sdcard was corrupted. What's the current status? Edited October 28, 2016 by Guest 1 Share this post Link to post Share on other sites
Glamdring 1 Posted October 30, 2016 in Side fans and extrusion stopped working (edited) It's still not working, I've tried it with other gcode files that used to work and they don't, the print head still moves around and the back fan goes, but it doesn't extrude and the side fans don't work, I have no idea where to even start fixing it. edit: restarting does nothing either Edited October 30, 2016 by Guest extra point Share this post Link to post Share on other sites
neotko 1,356 Posted October 30, 2016 in Side fans and extrusion stopped working Does the extruder 'move' when loading new filament? Maybe the filament is chew on the feeder and is slipping? 1 Share this post Link to post Share on other sites
Glamdring 1 Posted November 1, 2016 in Side fans and extrusion stopped working Yes, it was! the feeder was chewing into the filament, I removed the material, cut off the chewed part and re-entered it however once the filament reached the print head, the knurled wheel kept slipping/jumping back and started to chew on the new filament. As I only noticed the fans weren't working when it stopped extruding so I imagine they'll be different issues, so how would I stop the wheel slipping? thanks Share this post Link to post Share on other sites
neotko 1,356 Posted November 1, 2016 in Side fans and extrusion stopped working Check the feeder tension. It might be too strong. This is how it looks inside (don't open it is just to explain) The screw moves the nut that makes the spring be more or less tight. (The indicator on the bottom is maximum pressure and on the top less pressure, don't overdoit on any direction or the small plastic indicator can snap) 1 Share this post Link to post Share on other sites
Glamdring 1 Posted November 2, 2016 in Side fans and extrusion stopped working (edited) Yes! that seemed to do it, it's printing fine now, thanks loads! however the side fans still aren't working, have any idea why those aren't moving? edit - just started halfway through a test print, no idea why Edited November 2, 2016 by Guest now incorrect Share this post Link to post Share on other sites
Glamdring 1 Posted November 2, 2016 in Side fans and extrusion stopped working half way through the test they just started working again, I don't know why, but it's all working now, thanks! 1 Share this post Link to post Share on other sites
