First-time poster here. I am new to CNC and have a Nomad 3.
I am trying to cut out a part that has a an icosahedron-shaped hole in it (so lots of sharp angles)
My thought was to use endmill #102 (1/8" square endmill) as a first pass and then a 30’ V-bit to get the sharp angles in the icosahedron. In MeshCAM I generate a “Unified Finishing” toolpath with the first endmill and it looks very reasonable.
How can I generate a second toolpath to do a finishing pass on the remaining stock with a different bit?
I tried just making a second “Unified Finishing” toolpath with the V-bit but it quotes 10,000+ minutes to machine and seems to work over the original stock instead of the new cut part made from the first pass.
