Started from a 3D model (e.g. from thingiverse), projected to a grayscale heightmap using STL2PNG utility (see https://community.carbide3d.com/t/from-stl-file-to-carbide-create-pro-screenshots-included/17420), imported that in Carbide Create Pro, used one 3D roughing toolpath with a 6mm 2-flute square endmill (tool "10", and two 3D finishing toolpaths oriented 90degrees from each other, using a tapered endmill (they rock!).
