What causes x-axis shift

what could be causing this shifting in the layers?

ive never had this happen before...

 

is this a slicer / code malfunction ? 
 

trying to find a solution, not too sure where to start though.  Everything looks fine in cura preview with the print layers

 

I’ll try to re-export the model as obj and see if anything changes

    It is not clear from your photos, but it looks like the part came off the glass bed, and started sliding around? If yes, the problem could be your bonding method (or the lack of, or you forgot to use one), or a bed height leveling problem?

     

    If the model would still be stuck to the glass at this point, then maybe you have loose pulleys somewhere, maybe on one of the stepper motors? Or maybe something hit the printhead while printing (cat, dog, kid,...?), causing it to skip steps? Or printing too fast for your stepper motors, so it could not follow and skipped steps?

     

    I guess it must be something along these lines...

    You were right Geert_2!

     

    the left stepper motor bolts became sightly lose.  The belt was loose and the speed was causing the teeth to skip and causing the print to shift...

    tightened it up and all good

     

    thanks again

        (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.
