I cooked up the design in Sketchup and then used MeshCAM to generate the tool paths (g-code).
I was in two minds about using a ball nose or an ordinary end mill. I went with the endmill. I need to study the MeshCAM system more and figure out how to change endmill in the middle of a job without throwing my Z axis out.
Everything came out pretty good.
I initially wanted to have little bowls as indents so the game could be played with marbles. But Sketchup was barfing on that. So I just made everything flat bottom.
Once I get a tool that can manage the curves better I’ll try harder ant getting good curves with MeshCAM. I’ll actually use a ball nose and see if I can increase the passes or something to make it smooth.
