UMs5 - Print Core Loaded/Stuck but printer doesn't register it

Posted · UMs5 - Print Core Loaded/Stuck but printer doesn't register it

Help! I must have done something wrong when changing print cores from AA 0.4 to AA 0.8...the printer accepted the new print core but didn't start my print. Now the print core is STUCK but the UMs5 says no print core is loaded. When I try to "load" the print core, it just tells me to insert until it clicks, but since the print core is already inserted it won't read it and I cannot get the printer to think there's somethin g there so I can then unload. I am also unable to remove the bowden tube to pull out the material to then remove the print core. I also do not know how to clean the back of the print core since it's already loaded. What do I do?

    I have also had the "ghost print core" a couple of times. Wit me it course after a print is done. 


    Some times I have had luck in just turning of the printer at the back, and when it powered on again the core was registered.


    If that doesn't help you can, unclamp the bowden at the back, release the fillemet tensioner and pull a bit of fillment throw, then you can cut the fillement and pull of the bowen.


    carefully try and "cold pull" the fillemet out and if not possible cut the fillement right between the cors metal part and bottom of the print head.



    It is prity hard to cut without damaging the print head, so if in doubt I would check if it's covered by the warranty.


    Why do my posts always double post pictures??

    @NBull thank you for the help! After turning off/on, Ultimaker magically registered the print core again. I was able to change the print core, manually remove the filament & cut off the damaged parts (the feeder ground it down on one end and it had gotten pretty messed up on the other). I re-loaded material and got my print going in no time. Thanks again!

      • 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
