I am writing concerning a big problem we had today with our Ultimaker 3. 


We sent to print pieces during the weekend and when we arrived Monday morning it was a complete disaster, attached pictures. For some reason the plastic had overflowed both print cores so much that  the plastic clog opened the print head and went through the fan.  At the same time it was so much plastic underneath the plate that was blocking the movement, actually on the screen was “The x or Y axis is stuck or the limit switch is broken”.  It was so stocked that the metal axes jumped out of the black support pieces. The half printed pieces were nicely stock to the glass. 


We are sure we will need to change print core B , but we are still hopeful that we can clean the print head. Anyway before ordering anything we would like to know what happened. We are not sure what was the chain of events to arrived to such messy outcome. We are wondering If anybody have seen something similar or  may guess what has happen. 


The printer was working nicely the days before, it was clean and running. So we would like to know if it was only a mechanical problem that can be solved with a new print head or an internal one that will happen again.



Thanks in advance

    Usually when this happens, it is because a part of the print has come loose and slid around right up under the nozzle, leaving nowhere for the plastic to go but up and into the printhead.


    I see a big white blob on the rear left of the printer. That would be enough to create that issue and start a chain reaction from core 1 into core 2. Were the circular parts loose as well?

    Thanks Kmanstudios!!


    Do you mean if the pieces we were printing were loose? The pieces were attached nicely to the glass, only that it was some melting marks on one of the pieces. 


    I am not sure about were is the big blob you mention. On which picture do you see it?

    The blob I saw was on the second from top. If there were melting marks, that could also be a problem as that could be where the buildup started. It is a runaway affect when it happens.


    The melting marks could be from the plastic blob getting dragged a bit over the surface of the print.

      • 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
