That is funny in my retrofit we kept even bigger sem servos at x y and z axis
so if that is the spindle motor it is fine as well
that can be easily done by VSE 160 granite device with 0.10 v interface

and the axis x and z get us the spec of the motor or exchange it.
so i would use linuxcnc
triple beast bob board
lead shine boards for the x and y steppers
and the 0.10 volts for the spindle
endstops and you are done

you can get the encore signal from the servo back as a,b and z to make threading possible,

And i guess it will be possible with mach3 but i stay away from windows in that case because you get all problems of windows and no benefit
windows is not an real time system

sounds doable think I'll just change the steppers and drives then

could you maybe send me some links for the stuff I'll need?

greatly appreciate your inputs!

ps. for the C-axis I'll attach an auxilary servo on the final spindle but let's not worry about that for now

I have very little experience with mach3 by now so it wouldn't be much of a step back to get started with another software (i.e. linuxcnc) so I guess I'll just follow your advice all the way
-linuxcnc basically has the same programming capabilities as Mach3 right?
