I'm building a machine to cut out guitar pieces.Guitars are mostly hardwood so the machine is pretty robust.I was wondering what would be a good choice for motors to run this thing, and also which programs would be good from design to g code,I'm a mac user and know I have to buy a pc and I have never used autocad or any 3d programs.The machine is 2 by 3 and I plan on using a porter cable 2hp router or smaller if I can get away with it.Thanks in advance,there's alot of brilliant people on this website I have learned alot in the 2 weeks I have been here.
