Cura Slicer Fail (Fills a big Hole)


Recommended Posts

Posted · Cura Slicer Fail (Fills a big Hole)

Hi Ultimaker Community,

 

the Cura Slicer fills ab big hole in a cover plate that I want to print.

It is a hole for a antenna of a orangePi Zero.

I build a case for this OrangePi in blender.

 

The strange part is that the hole is shown in the cura edit mode

but is gone in the preview mode :-/

 

Can you pleas help me?

 

 

Cura Version: 4.2.1

Printer: Creality CR-10

OS: Windows 10 LTSC 64bit

    I suspect your model is not watertight, or “non-manifold”, or contains internal geometry. Blender is a mesh editor and so is very easy to have these problems. As such, Cura gets confused about what is inside vs outside.

     

    Check “X-ray mode” in the model preview—any red is bad. Try the Mesh Tools from the Cura marketplace. Or try the repair tool at service.netfabb.com. Requires registration, but is free.

    Many thanks, Martin.  I had the same problem with Cura filling what it should not and could not get it solved until I did this.  The problem is the default is that overlapping volumes will be unioned and nowhere is it mentioned that that is the case.  I just un-checked that box and model prints as I specified it.

    I am having the same problem with a file I downloaded from Thingiverse. It will slice correctly in PrusaSlicer but I am not familiar with it enough to get correct settings. Using Cura 4.8 or 4.9 it fills the holes. X-ray view shows the file is ok. Turning off Union Overlapping Volumes does nothing. I have Mesh Tools plugin installed.

    Models on thingiverse are sometimes in bad shape.  It's almost certainly a defective model. There are lots of ways to fix it.  I'd start with this method:

     

    In the upper right corner of Cura click "marketplace" and make sure you are on the "plugins" tab and install "Mesh Tools".  Then restart Cura.  Now right click on your model, choose "mesh tools" and first choose
    "check mesh", then "fix model normals" and "fix simple holes" to see if that helps.  Cura doesn't fix most issues so...

     

    If that doesn't work netfabb will likely fix it:
