Svg overlaying grayscale?

not suggesting you do this, but what you want sounds a bit what I did way back in Test cuts with the newly installed spindle

unfortunately that wasn’t with carbide create but that’s the effect you’re after more or less

there must be a workflow where you load the SVG into blender, make it raise itself a little bit into a 3D model so that you can stack it into carbide create
(or you can do it as grayscale bitmap using inkscape)
