Cura creates top layers within the model


Recommended Posts

Posted · Cura creates top layers within the model

For some reason the 4.13.1 seems to create top layers inside the model. This did not happen before the update. I am sure there is a setting that fixes it but I can' t find any. The layers just above the weird top is not connected to the faulty one but floats one layer above it.
I have not tried printing since it is a 3 day print that might turn out bad. 


Does anyone know what is going on?

    It is hard to know what we are looking at without seeing the model and your print settings, but I blame your model. It may not be "manifold", which confuses Cura.



    If you want a better diagnosis, please save a project and post a link to it here.

    File -> Save project...

    I would be super happy if it was the model, but it is thoroughly checked. No errors. It happends to a few other models as well. Like there is a limit to the height of the model. But ill post the project file, and I am super thankful for any help 🙂

    "...but it is thoroughly checked. No errors."

    You should have a talk with your checker.

    From  https://formware.co/OnlineStlRepair:


    --> 0 Naked edges (?)
    --> 0 Planar holes (?)
    --> 0 Non-planar holes (?)
    --> 586098 Non-manifold edges (?)
    --> 390147 Inverted faces (?)
    --> 0 Degenerate faces (?)
    --> 780879 Duplicate faces (?)
    --> 0 Disjoint shells (?)
    -> Repairing: 100.00%
    ----- Repair completed in 39429ms ------
    -> Vertex count changed from 195368 to 196569 (+1201)
    -> Triangle count changed from 781464 to 393134 (-388330)


    After opening the file I checked the model with @ahoeben's Mesh Tools and the "not watertight" warning came up.  I exported the model as an STL file and uploaded it.  MS 3D Builder also noted defects in the model and was able to repair it (but the formware site gives a report).

    I've attached a repaired file.

      • 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.
