Bug in stl import


Recommended Posts

Posted · Bug in stl import


I am trying to import a stl model into cura, but it looks like it is not sliced correctly. This is the lid of a box and it should have an edge and then empty inside. It looks like cura is filing up the empty space. 


I am using version 4.5 on linux with default settings. 

Is this a bug or am I doing something wrong? I am quite new to cura and this model seems to be imported well in Slic3r. 


Attached stl file and the screenshots of the model + sliced.

    This is a common issue.  If you created this in sketchup go back to your drawing and note that some walls are white and some are gray - right click on the gray walls and select "reverse faces".


    Best to fix your model.


    Alternatively look at all the mesh features in cura - try unchecking "union overlapping volumes"

    MeshTools also has an option to "fix" the normals. In case of flipped normals it unflips them. I am considering making it an option to always fix normals on import, but that may slow down loading huge models.

      • 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.

      • Ultimaker Cura 5.6 stable released
        Cura now supports Method series printers!
        A year after the merger of Ultimaker and MakerBotQQ, we have unlocked the ability for users of our Method series printers to slice files using UltiMaker Cura. As of this release, users can find profiles for our Method and Method XL printers, as well as material profiles for ABS-R, ABS-CF, and RapidRinse. Meaning it’s now possible to use either Cura or the existing cloud-slicing software CloudPrint when printing with these printers or materials
