  1. Hi guys, Thanks for all the quick answers. I've now managed to print on a friends printer an Ultimaker extruder clip (http://www.thingiverse.com/thing:46157) as recommended by Francis and that works fine. I've been making some "torture tests" and so far it did not pop out a single time. Thanks again for all the support, great community here! Mich
  2. Thanks a lot for the quick answers guys. Unfortunately, its going from bad to worse. So far, I've removed that tape and I scraped the inside of the Bowden cable with a razor, to reduce chafing. This did not help, it's seems to be popping off even more often. As for temp, speed and layer height: I've been printing with PLA, 100mm/sec max or slower, .1mm layer and around 210-220C. And I've tried to print the diverse solutions you proposed, but the cable always comes off during the print. I even tried to hold it manually, but I don't want to force anything. Anyway, it came off again. I did manage however to print the Ultimaker extruder clip (http://www.thingiverse.com/thing:46157), but it broke when I tried to put it on. :-| Now that I've changed to ABS, the Bowden cable comes off again. I'll go to our FabLab tomorrow and print a few of the parts in ABS there. I'll keep you posted. If you got any other ideas, I'll take them... :mrgreen: Thanks for the help anyway. Mich
  3. Hi all, I am a proud new owner of a few weeks old Ultimaker. Until now, the machine has been performing fine and as a newbie, I've learnt quite a lot these past weeks. :smile: Recently however, I am not able to print anymore, as the Bowden cable keeps popping out of the quick-fit coupling all the time. I did replace the tape around the Bowden cable (I came prepared like that from Ultimaker) and put it in tightly, but that does not help. The feeding is fine, the filament goes forward nicely, but I guess that the friction is simply too high when it passes from the feeder into the bowden cable. It seems that the QFC is simply not able to keep the Bowden cable fixed. The filament i currently use is the grey PLA issued by Ultimaker. All the rest of the hardware is Ultimaker, no tweaks so far. I've been reading a bit in the forum and it seems that this is quite a common issue. I've also found these two solutions: http://www.thingiverse.com/thing:10799 http://www.thingiverse.com/thing:40544 I'm a bit uncomfortable with putting screws into the feed mechanism, so does there exist another solution? What did you guys do and what works best in your opinion? Thanks in advance for your answers, Mich
