I may have broken my Bowden HELP! - solved

Recommended Posts

Hi there,

After trying to dismantle the hotend on my Ultimaker original, only to get the fan out, I accidentally pulled the white bowden tube clamp up the PTFE tube. I know that this is not coming down again.

Any suggestions from anyone that has done the same thing would be most welcome.

I feel like a complete idiot :c/

Many thanks.

Pushing down the white clamp, while pulling the tube, should work for getting the tube out.

Might need some force, Bowden tube might be grooved from the Bite

The metal teeth 'Bite' only when you or the filament pull the tube.

Pushing in should go easy, don't forget the 'horseshoe' to keep the clamp up.

You might need the alankey (screw)driver to guide the tube in the white Teflon hole, Does not always line-up perfectly.

I remember back when I was assembling the printer the first time that I had let this happen. Even with the force of the four long thumb screws this thing was not moving. Fortunatly back then I had not put the clamp on the other end of the tube, so I just slid the clamp all the way down the tube and off.

The problem now is that there is one at each end. I suppose I cut a bit off the PTFE tube at the extruder end, but I'm still thinking there may be another way.

Don't worry, I can't see how you could've caused any sort of harm. Just remove the blue (or red) horse shoe that sits around the white piece. This should be enough to let you slide the white piece off the tube. If not, try to use your nails to bend the four tabs out a little bit so that the metal blades inside no longer bite into the tube and slide it off (or maybe use a collection of tooth picks or something :) ). But it really should be enough to remove the horse shoe.
