Sorry, it is a proprietary file but if I have time to duplicate the problem on another file I can share, I will.

I figured it out. Once you have a blocker set up, you have to go back to the settings and uncheck "Generate Support" and recheck the option and then slice. That is terrible programming. On top of that, even with the "Enable Support Brim" Unchecked, it still wastes material by making the brim for the support structure it is now blocking. What a waste.

OK, I can not get this to work. I created the eraser and covered the area that I do not want support and it still makes supports within that blocked area. What am I doing wrong?
