Ah, CloudCompare is not really the best meshing tool (it's not Meshlab ;) but we do have two options to compute meshes: either the Delaunay 2.5D Triangulation (is it what you used here?) or the 3D Poisson Reconstruction (much more evolved, but you'll need normals and it seems a little bit overkill for what you have). But it all depends on the actual shape of your clouds.
As it's a CNC, I guess we can consider the input clouds to be 2.5D only? I mean there's no overhanging or two points one above the other along the Z direction?

Interesting I had to re-Register to login and answer this, and I did not see what I had posted yesterday. This Cloud Compare is so well done compared to other programs. Yes and I am working my way through the excellent documentation. The Delaunay 2.5D Triangulation is what I used and it created a wonderful STL file. Thanks for letting me on board.
