Re: Mixing steppers and servos on same machine?
Linuxcnc won't care if you mix servos with steppers. It depends what sort of servo drives you have. If they were step and direction, you could use a 7i76e but if they were 0-10 volt, you could go with a 7i76e and a 7i77 that will allow you to do what you want.
I'm still not convinced you need to use servos on a plasma or waterjet because there are no cutting forces so the motion environment is very predictable. The mill or router has quite different parameters to plasma so good luck with your multi process machine. I had that in mind and ended up going with a dedicated plasma machine.
