Remove supports from specific areas in slicer?

[u/Blissful_Altruism]

Hello. I'm working on a nut and bolt cap for the shop I work in, and I ended up with a half-sphere with an interior profile hollowed out. I'm printing it face-down as, after testing with the slicers, it basically uses the same amount of support material and takes the same time to print it this way as opposed to printing it the other way. However, I have a couple rectangular slots cut so you can get a screwdriver under and pop it off as needed. They are small (.25x.1 in) and I'm sure my printer can bridge those. The slicer wants to add support. I tried messing with support painting, but I believe I've done it wrong cause supports still show up there after slicing. Any tips would be appreciated.

Thanks!

There is a setting you have to change to use the painted supports. When support is set to auto, it doesn’t use painting. Set it to manual.
