Cura does not print holes at bottom

[crrizzman 0]

Hi there,

 

I want to print a file I made with blender.
It has a hole at the bottom, but Cura always slices/prints the complete bottom layers without the hole:

And here a screenshot from blender with face orientation on:

 

 

So the normals look good to me and I tried several settings in cura (Remove all holes is off, Bottom Layer Count = 0 etc.)

But I still get the object sliced without the hole at the bottom.

 

Does anybody have an idea what I could do, so Cura prints the object with the hole?

I had a similar issue and found "Make Overhangs Printable" was ticked in the experimental section in Cura.  If it's ticked, untick it, and hopefully that will fix your issue.

I just found the problem.
I had missing faces betweend the 2 bottom layers, so the walls were open.
I selected on the edges of the two layers and clicked on "Bridge Edge Loops".

 

 

Now it works as expected in cura.

Glad you got it working.
