Support blocker issue

[Outpost31d 0]

Can't seem to get the support blocker to work.  When I click it and try to place on my model my model blanks out?

Strange. Can you share your model?

Sure can, thnx!

Hmm, works just fine for me.

Can you save the file as a project? That way I also get your printer configuration and settings.

Sorry, I still cannot reproduce this. Does it happen with just this model, or with any model you try?

Thanks for the effort, yes its the same with all models

I have the problem described above on Ubintu (17.10 and 18.04) using the AppImage. On Windows 10 it works fine for me.

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?

Hello.

 

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.

I have finally figured out what is happening. Here's a fix:
