John why don't you just ask Dan.I see you follow him why not just ask him ??
You'd only need a 3 axis machine which aren't as expensive as a GM 5 axis machine - though will shape betters at a quicker rate If I won the lottery it would certainly be something I'd do - especially coming from my engineering background and interest in this field
No that's just for machine plus basic software and maybe tooling if your very luckyAll the programmes etc to do bats would need to be written
surely you need more than just the cnc machine? or is 400k for the machine and all the cpu, design stuff you'd need as well?? 400k isn't that much if you can literally churn out thousands of bats
