What causes Cura to ignore interior details depending on part orientation?

[Aston01 1]

I am using 4.13.1 and having a weird issue where the slicer ignores the interior details of a model almost like they aren't there whenever I have the model oriented to the bed with its face down.

 

 

If I stand the model up on its end all the sudden the details become visible and get sliced.

 

Is there some setting I accidentally clicked that causes this?

In most cases, it is non-manifold models.

Apparently according to SuperSlicer/PrusaSlicer it is in this case 🤷‍♂️

 

I attached the model if anyone wants to check.

The model looks manifold indeed. That's why I said "in most cases", not "in all cases".

 

If you save the model from Cura with File -> Save project... it also saves all your settings and I can have a look at those. Some settings can also cause this.

If i would make a guess...:

 

"Mesh Fixes" -> "Remove All Holes"

 

...would have exactly this effect (in combination with zero percent infill).

 

Though... I can't imagine why anyone would enable this without a good reason?

And you sir would be right on the money. How that setting ever even got turned on I have no earthly idea, it wasn't even a visible setting when I went to double check after your comment.

 

I appreciate both of your help sorting out the issue.
