CURA BUILDING SUPPORT STRUCTURE WHERE THERE IS NO OVERHANG

[SEMCOM_3D_1 0]

Hi all, 

Cura is automatically building support on the outside of the model where there is no overhang. Any idea why this is happening?

set support horizontal expansion to zero.

 

Usually, that is very useful when printing PVA but not in this particular model.

I tell ya, everything runs in streaks and there have been some bad models show up here recently.

 

Are we sure that model is OK?  I ask because when odd things like that happen - Cura must have seen something or it wouldn't have put the supports there.  Does anything show up there in the X-ray view?
