[ HELP! ] Ultimaker3 - Material spill blocking the print head fan

Posted · [ HELP! ] Ultimaker3 - Material spill blocking the print head fan

Hello,

Complete newbie here. After a few successful small prints, I launched a rather big print remotely from home (with no video return - realized too late that the firmware needed update). Next morning at the office, realized the catastrophic results : nothing got printed, but a huge heap of melted (now solidified) material around the nozzle and the fan. Even the fan bracket is stucked, can't be opened. Material can't even be unloaded, everything seem to be glued together. Please have a look at the attached pics. Any hope to recover from this mess ? Thanks !

    Sorry to hear that you ran into this issue. We have some postings here in the forum with similar issues and there you find also some helpful tips. 

     

    Basically you have to heatup the print cores manually but that alone is often not enough. So use a heat gun to carefully soften the material and remove it piece by piece from the head. But be careful to not melt the plastic of the print head itself. A temperature regulated heat gun is sometimes better but a normal one is also ok. 

     

    This issue often happens, when your bed adhesion is not good enough. The object gets loose and then moves around with the print head. The print core still extrudes the material, but the nozzle sticks on the object so the filament uses other ways to extrude.

    Thanks a lot for the tips. I'll go search for some rescue operation examples !

      • 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
