CURA 4.11.0 Bug, Greying out huge parts of model for no reason


Recommended Posts

Posted (edited) · CURA 4.11.0 Bug, Greying out huge parts of model for no reason

I have a bug with CURA where when I slice the model it gets a huge chunk cut out of it and greyed out for some reason. I have literally no idea what is causing this and other slicer programs besides CURA do not have the same issue, anyone have some insight?

I've attached images of the preslice model and the sliced version, along with my CURA log, the model itself, and the project file.

    What you have there is a bad model.  There are 30 different parts combined and a lot of incomplete areas.

    When the "model is not watertight" warning comes up it indicates problems with the model.  Each slicer handles the models a bit differently.  MS 3D builder noticed the problems right away and was able to repair the model.   It then sliced correctly in Cura.


    This is Cura in X-Ray view.  The bad areas are highlighted.



    This is from IdeaMaker and you'll notice in the right lower corner "model invalid".



    Here it is sliced in IdeaMaker



    This is PrusaSlicer and it also looks a lot like Cura sliced it.



    The other 15 slicers I have installed came out pretty much the same.  That's a bad model.
