SOLVED Cura 3.0.3 filling in holes

[sinned 0]

Hi all-

I update to Cura 3.0.3. I was using the Wanhao edition of Cura previously. Worked fine for me, thought to jump to the newest yesterday. When I read the FAQ, I understood that 3.0.3 would migrate settings if installed side by side to the old version.

Here is screenshot of some gears I am trying to print. 3.0.3 is infilling the bore. This is under both recommended and custom settings.

In 3.0.3 the Mesh Fixes -> "Remove all holes setting is unchecked.

I used the same .stl that I generated from AutoCAD for all 3 gcode generations. I put it into S3D too to check the model.

What am I missing that would infill the bore of the model?

TIA

Hi, could you please post links to the model (stl) and the gcode that doesn't have the hole. Thanks

Disable "Union Overlapping Volumes" in the "Mesh Fixes" section. If your model has the surface normals wrong for the holes this option closes the holes.

Thanks Dim3nsioneer, that seemed to fix it. I will look at how I modeled the part with blocks/arrays. I wonder if that caused the issue.

Sometimes I think that AutoCAD exports to like it used to print in the pen plotter days- by order drawn not by position. The travels in my models seem ridiculous.

I have the same problem with these files.

and nothing I do seems to work, it's like the hole on the bottom doesn't exist!
