Posted · Can't changing print core by Change print core procedure

I can't change print core BB to print core AA.

When i press "Change" botton in Configuration tab on screen, Normally Print head will move to center of printer and we have to press comfirm on screen and change the print core.

but now when i started the procedure, print head move close to front door (like cleaning print core) , so i can't open fan bracket and the screen unresponsive for a long time.

so, i tried to on/off the printer a few times but can't fixed it. 


Has anyone ever been like this or have any ideas to fix it?

    I have seen this, and it is really annoying.


    It is using the Print Core Change button, the print head will move all the way to the front of the printer, and off to one side (say the right side if changing print core 2), and the print bed lifts all the way up. 


    There is no way to open the door on the print head in that configuration.  You can open it enough, and move the print core enough to break contact with the mating board (fool the printer into thinking it was replaced).

      • 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
