i have a big problem printing some STLs. The STLs are open on bottom and top. However, when i enable the top/bottom layers in cura, cura closes the bottoms and tops.
If i disable bottom/top layers by setting them to 0, cura also does not print some horizontal parts inside the model that should be there.
This is my test-part: https://www.thingiverse.com/thing:2115282/#files
Cura 3.1 is used.
I made some screenshots:
1: In solid view you can see the horizontal part in the blue circle.
2: with top-layers enabled, the model is closed on top (but should be open)
3: inside the model now looks good
4: without top layers the part is missing
So it seems that either i can
a) have the model open but parts missing
b) have the model closed but inside its OK
I already tried the "cut mesh" tricks: the mesh-part where i have to enable the top-layers always inserts an artificially inserted closed top/bottom layer at its boundaries -> no help there.....
Any help is greatly appreciated!
