Breakaway support intersects model with Cura 3.5.0/3.5.1 (UPDATE: Fixed in 3.6)

[P3D 46]

Hi @all, I have a problem with using the Breakaway support with Cura 3.5.0 - it generates lines that intersect the model, as in the following screenshot:

 

 

Does anyone have any idea what could cause this, and how to fix it?

Does your model look ok in x-ray view?

[P3D 46]

To me, it does - and it should, since the model comes straight out of CAD export, and there are no weird faces or anything in CAD. I have attached a project file exhibiting the problem.

Hi @P3D, I have just sliced your model using a Cura built from the master branch and it doesn't show those lines so, perhaps, the problem has already been fixed for a future release?

@P3D I also get it with Cura 3.5 on layer 24. But it works with Cura 3.4.1.

Thanks for checking this out! So I'll probably have to setup Cura 3.4.1 in parallel...

The bug is still there with 3.5.1 unfortunately...

Check this for a workaround untill Cura 3.6 is released: https://github.com/Ultimaker/Cura/issues/4575

This seems to have been fixed in Cura 3.6. Great Work!
