problem with surface quality


Recommended Posts

Posted · problem with surface quality

I have this problem when printing with 0.8 nozzles with PLA on a 0.4mm layer height. when setting 'z-seam alignment' to 'user specified' (see attached screenshot) i get this poor quality, seems like the PLA is coming in too late. never had this before but since a few weeks nothing helps to make it better. so question is: what settings do I need to change?

cheers, Leon

    That's underextrusion but only on the end of the part.  Please post your project file.  In cura menu do "file" "save project..." and post that file here.  It will contain your model among many many other things so hopefully it's okay to post your model.


    Without seeing your settings (all 500) and your model, make sure "retract on layer change" is disabled and consider unchecking both jerk and acceleration control.


    Unchecking jerk and accel will increase ringing which is visible and some people think is ugly but what you have here is much worse than ringing (in my opinion).  Unchecking jerk and accel control will increase part accuracy as shown with calipers and such but will increase ringing features which are too small to measure with a caliper but are quite visible.

      • 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.
