U3e - leveling failure, core 2 switching test failure


Recommended Posts

Posted · U3e - leveling failure, core 2 switching test failure



My U3e acting weird recently. The Printcore 2 switching movement has some offset, it does not move to where it should click to that plastic tab, instead of it does the movement few centimeter further. Therefore it does not click/switch, just moves in the air. I tried in the diagnostic menu, switch test, the result is the same. I reset the printer loaded the firmware again and it is the same. I guess this gives me the leveling failure, because the core 2 is always retracted...but maybe not. 


When I send a file to the printer it starts to heat up and does the leveling. But that fails because the core2 is scratching the glass hard. I have tried manual leveling, but the rear, third leveling screw is already out of the tread, I can not raise the table more. 


I have Bondtech feeders installed, and after firmware update the necessary settings were changed (feed speed, tube length, step/mm) I dont think this affect the step motor movements for x,y,z, cores and bed.


Can you guys help me, or tell me what should I do to have my printer back to normal?


Thank you

    The printcore 2 "up" position works, but maybe it also faulty, but still has some surface to catch, when I try in Diagnostic, it works, but the Printcore 2 "'down" position is wrong, the head comes further forward, it does not click to the tab.

        (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.
