Support blocker issue

Recommended Posts

The only thing I can think of would be that the depth picking is not working (which could be a GPU/driver issue), and the support blocker gets placed very far away from the model. A patch was just merged that at least does not block slicing when this happens, but it will not fix the placement of the Support Blocker meshes. Can you save a project when Cura is in the "Unable to slice" state, so I can check this theory?

I had similar problem.

My laptop has integrated Intel GPU and NVidia GPU. I forced driver to use NVidia GPU for Cura and now support blocker works well.

I had the same thing happen to me. Using Linux Mint 17.3.


I did have one case were I did have the blocker appear but it was way way off in the distance and I had to bring it back. I still don't think it was working correctly however. When I retried I have not yet been able to duplicate it.

    • "Back To The Future" using Generative Design & Investment Casting
      Designing for light-weight parts is becoming more important, and I’m a firm believer in the need to produce lighter weight, less over-engineered parts for the future. This is for sustainability reasons because we need to be using less raw materials and, in things like transportation, it impacts the energy usage of the product during it’s service life.
