My Ultimaker 3 Extended Will not extrude material


Recommended Posts

Posted · My Ultimaker 3 Extended Will not extrude material

I have tried:

  • unloading and loading the material,
  • changing the printcore temp,
  • replacing the printcore itself

I am using black Nylon Filament from ultimaker, with an AA 0.4 Printcore.

Any help is much appreciated.

    1. Clean the printcore with pla or cleaning filament. 

    2. Make sure the nylon is dry. If your printer is fully enclosed you can heat the bed to 60° and leave the roll in there for a coupple of hours. Moisty nylon is prone to clogging nozzles.


    You can also open the feeder to clean it. Last time I had problem with random under extrusions I opened it and found a small piece of filament that probably interfered at its own will.


    Be careful though, there's a spring inside that wants nothing else but jump out ejecting other parts...

      • 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
