Ultimaker S5 - wiggle on printhead in Y-axis

Hello,

 

I recently noticed allot of wiggle in the printhead on the Y-axis. Is this normal?

It looks like the printhead is connected with 4 bolts (see picture). 

 

I checked the manual to look if there are any specification how tight the bolts need to be in Nm. 

But I couldn't find any reference.

    So I tightened the 4 bolts a little bit on the printhead. 

    It reduced the play in the printhead allot in the Y-axis direction.  

     

    This is my first printer so i'm not sure if i made things better or worse.

    Anyone else ever had to tighten these? 

     

    Guess the worst that could happen is that i screw up the bearings.

    Hello


    In practice, the observation that X has less play than Y is normal for this printhead. Because inside, the axle has one bearing less in the Y direction.

     

    Here is a picture I took during a maintenance / repair of the printer.  A bearing in the middle.

    I also tightened it a little on mine. Theoretically, you can't damage the bearing because it is positively locked in a recess in the cover. Even after tightening, the bearing still has more play than the other one.

     

    As a constructor, this can make you think. But what I find more important is that it works like this.

     

    Many greetings

        (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.
