Weird under extrusion UM2+

Recommended Posts

Posted · Weird under extrusion UM2+

Hi all,


I am currently printing this part on my Ultimaker 2+ with Ultimaker PLA and i get this weird under extrusion.


I am under the impression that there is something wrong with the filament. I have printed with other PLA's from Ultimaker and third parties with no problems. I have started printing this part with this filament before and the nozzle got completely clogged. When cleaning it with the atomic method I come across some leftover filament in the nozzle that I could not push through, even with the highest temperatures. After completely cleaning the printhead I started printing this part again. First it went well but soon after I am getting this result.


I have not made any changes to the default print settings.


Any ideas what could cause this problem?

    Just restarted the print with a different brand of PLA and now I have no problems.


    Here is the Ultimaker PLA that is causing the problem. This is normal PLA right? And you should print it with the PLA settings on the printer? Could it be a manufacturing mistake?

      • 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
