Filament Stuck in Print Core. Can't Remove Print Core.

Hi everybody. I was following the procedure to clean the print core, hot then cold, and during the hot phase, the PLA filament broke off just above the housing to the print core, a BB 0.4. I can't pull it out and can't push it in, with or without heat. I'm tearing my hair out. I'd happily toss the print core but I can't get it out because of the protruding filament. 

 

It's an S3, purchased around May 2020. Ideas? -Charlie

    Hello Charles,

     

    I am very new to 3D printing so I am certainly a beginner but I would think you should be able to pull the filament out if you heat up the print core. I know you said it did not work cold nor hot. But I think you should try again by heating the core. Maybe by setting the temperature VERY high it should work.

    You can achieve this (as you probably know) by going in the printer's menu.

    (English is not my native language so I hope you understand what I meant)

    Hi Charles,

     

    As the bowden tube is removed you can just lift up the withe locking ring, now you'll have enough space to use a "long" a tanned tip rod to grab that filament.

    Heat the nozzle to 200 deg. C., then pull it out, but be careful and not clamp the filament to hard.

    Never over temp the filament, as this might harden filament very much and destroy your print core.

     

    Anyway, good luck.

     

    Thanks Torgeir

    Hmm,

     

    Here is two pictures, showing how to do, -using an UM2 head top, same size as UM S3..

    Hi Ronald,

     

    Welcome in here,

    Here you will find lots of stuff about 3D printing, -this is the right place to be.

    Good luck with your new hobby.

     

    Thanks

    Thanks everybody. I heated the print core to 280C and pushed the filament down further. After 20 minutes, with serious effort, I pulled it out with needle nose pliers. 

     

    Victory!

     

    Much appreciated. -Charlie

    Shoot. It's weird. We were able to run a clean cycle of print core, the one that we unstuck, in the #1 spot, which worked fine, but when we unloaded and loaded filament, there was no extrusion. We swapped the AA 0.4mm for the other AA 0.4mm print core into the #1 spot and tried to unload and load and still did not get any extrusion. 

     

    We moved the previously clogged print core from the #1 spot to the #2 spot and it worked fine, so it's not the actual print core that is faulty, but the #1 spot. 

     

     

     

    What do you suppose is preventing the #1 spot from being able to work properly?

     

    Thank You. -Charlie

    P.S. #1 spot = #1 extruder

    #2 spot = #2 extruder

    Was there any error code related to this during the "heating period"?

    There have been some issues with correct seating -due to remains of filament, also dusty contacts inside the head that's attached to the cores when installed could create erratic contact problems.

    Maybe something happened here during the cleaning -"cold" pull?

    Only clean carefully with alcohol and clean rag..

     

    Thanks

    I've tried this method with no luck...

     

    Heated to 250 and attempted to pull out with needle nose.

     

    The filament will not budge from the print head... Any suggestions?

      • 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
