I have recently invested in a cnc router machine ,its only a small kit but it will do what i require it to do .. Not having one before and seeing what it can do is amazing .. But it has programs from aspire/,photo carve / mach 2/3 plus other programs you can buy . Just needs me to learn how to master the G.CODE .  This machine  if used right can earn you money from making basic name plates to like for like photo carvings . And also with what i think it can do is glass engravings on a sheet of glass using a diamond heavy duty industrial bit . And  maybe if i put a pencil in the collet it will draw like for like photos that you take and program into system . using a A4 sheet of paper . Cost  for machine around  £3800  / $5400     Ideal size for my workshop as its only small.
