Method for removing jammed PLA filament from bowden tube


Recommended Posts

Posted · Method for removing jammed PLA filament from bowden tube

I recently had a bad jam in my bowden tube. After several material changes, the wispy threads that sometimes get left behind bunched up and wrapped around the filament I was using. It was so bad it created a visible bulge in the tube:


Normal methods for getting a broken piece of filament out of the tube were of no use, given how badly stuck this was. Here is what worked for unsticking a really bad (PLA) jam:

1. Remove all the loose filament you can

2. Remove the bowden tube from the printer

3. Boil water

4. Hold the tube under the hot water at the location of the jam for 2-3 minutes

5. Quickly insert a clean, room temperature length of filament into the tube

6. Use the clean filament to tap the jammed filament repeatedly until it comes out of the tube

7. Allow the bowden tube to air dry, then replace on the printer

    Thanks for this post, I just used this method to unclog my Bowden tube! Some Colorfabb Bronzefill filament had been crushed too much by the feeder so it was too wide to fit through the tube properly and got stuck. I couldn't hold the tube or push on the filament hard enough to see any progress after removing the tube from the printer. So I filled a skillet halfway with water and boiled it, then turned off the heat. Then I used two twist-ties to coil the clogged tube so it could be fully submerged as shown in the photo. After letting the tube spend about a minute underwater to reach temperature, pushing the filament out was effortless.

    bumping the thread again, stumbled on it after a desperate Google search, lol. 

    I had some dissolvable support material split and get jammed in the Bowden. My typical techniques of using another piece of filament to push it out was futile. I resorted to soaking the tube in hot water overnight but that only dissolved the first few inches on either end. Still stuck. 

    Boiling water might do the trick, will report back.

      • S-Line Firmware 8.3.0 was released Nov. 20th on the "Latest" firmware branch.
        (Sorry, was out of office when this released)

        This update is for...
        All UltiMaker S series  
        New features
        Temperature status. During print preparation, the temperatures of the print cores and build plate will be shown on the display. This gives a better indication of the progress and remaining wait time. Save log files in paused state. It is now possible to save the printer's log files to USB if the currently active print job is paused. Previously, the Dump logs to USB option was only enabled if the printer was in idle state. Confirm print removal via Digital Factory. If the printer is connected to the Digital Factory, it is now possible to confirm the removal of a previous print job via the Digital Factory interface. This is useful in situations where the build plate is clear, but the operator forgot to select Confirm removal on the printer’s display. Visit this page for more information about this feature.

      • Ultimaker Cura 5.6 stable released
        Cura now supports Method series printers!
        A year after the merger of Ultimaker and MakerBotQQ, we have unlocked the ability for users of our Method series printers to slice files using UltiMaker Cura. As of this release, users can find profiles for our Method and Method XL printers, as well as material profiles for ABS-R, ABS-CF, and RapidRinse. Meaning it’s now possible to use either Cura or the existing cloud-slicing software CloudPrint when printing with these printers or materials
