how to remove material left inside the bowden tube

hi all, while I was printing the material ran out and filament remained inside the bowden tube, how can I remove it?

Hello, you should be able to pull out the horse shoe clip at your feeder, which is underneath the clamp that holds your bowden tube. When you have removed the horse shoe, you can push down on the clamp, and simultaneously pull out the bowden tube. If you do it correctly, it shouldn't require much force. 

 

Then you can pull out the remaining filament. This is easier when you make sure the nozzle is hot. Good luck!

Hi, thanks for the reply, I also tell you that the filament stuck in the bowden tube is near the nozzle, it is 10 cm of material,how can I do?

Same instructions apply, but instead of doing them at the feeder, do them at the printhead. It is also connected via a clamp and a horse-shoe. Good luck!

You can make it a lot easier to remove/replace the bowden tube by printing a couple of these clips. They are much easier to handle than the standard pneumatic clips. Pull it out, push the white ring down, and pull out the tube. Replace in opposite way: push tube down while lifting the ring, then insert the clip.

hello, is there a way to consume the remaining filament without removing the tube?

[SandervG 1,521]

Not without a compromise. In theory you could continue with the tip of a new role of filament, that will continue to push this filament into the print head for consumption, but since the feeder has no contact to your 'left over filament', it will not respond to retractions, which you will most likely see in your print through stringing etc.
