Cura won't acknowledge face-down boolean differences

Posted · Cura won't acknowledge face-down boolean differences

When the boolean-difference section of the sample is face up, it can be seen within the slicer-preview.  However, if you flip the model 180 degrees so the cutout is facedown, the cutout can't be seen at all.

The attached sample was used instead of my actual model because it's extremely basic, and watertight.  It also rules out possible causes such as 
- walls are too thin
- boolean difference too small to slice

 

Even with this most-basic model, I can't seem to get Cura to acknowledge boolean-differences, when face down.

    Sliced perfectly for me.  Instead of posting the STL file post the entire project which will include the STL and your rotations and your machine settings and profile and overrides.

     

    However my first guess is that you should check the "mesh" settings and make sure they are all unchecked.  Particularly "remove all holes".

    Project file attached.

     

    As it turns out, "Union Overlapping Volumes," and "Remove Empty First Layers" were checked in the mesh fixes section.  However, I still can't see the boolean in the preview after unchecking, and re-slicing.

     

    Thanks for the review!

    "Experimental" -> "Make Overhang Printable"

     

    Well... this setting does exactly what you ask for. It changes the geometry and...  "makes all overhangs printable"  🙂

    I can see the recesses in preview now, that appears to have been the issue.  Thanks!

      • 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
