Posted · Extrusion problem with Ultimaker 2+

Hi,

 

I started to have problems with my Ultimaker 2+ recently. It appeared quite suddenly, without any apparent reason. The PLA filament is not extruded properly, the invariably it gets stuck while the feeder continues to push the PLA and dislodge the plastic tube (bowden) at the top of the feeder.

 

I lost tracked how many times I dismantled the machine, and tried everything I could think of: obviously cleaned the nozzle, also replaced the nozzle with a brand new one, tried different PLA, cleaned again the nozzle, suspected temperature problem so I changed the temperature sensor…

 

Could it be just a problem of grip of the bowden in the feeder? I dismantled it but didn't see any particular problem.

 

I’m out of ideas, so any suggestions would be welcomed.

 

Many thanks.

      • Release Notes: S-Line Firmware 8.3.0 (Latest)

        Dustin posted a topic in Firmware,

        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.
