So I just got an awesome cnc machine, and I'm crazzy excited to update it's controls! I am looking for advice on some electronics and such. I have new servos but I'm not sure on the best power supply setup, for example. Should I supply each servo with it's own power supply? I'm also unfamiliar with the DIN rails and wire combs system and it looks very neat. I want my conversion to look just as neat but I'm not sure about the terminology of all of that stuff in the control box.
I am:
- removing all motion controls & replacing with new
- removing VDF to replace with new.
- possibly removing spindle motor to replace with more powerful unit
- have to place rotary encoder on new spindle motor for rigid tapping
- all axis stepper motors are going to be replaced with 3 n.m. servo motors and drivers which I already have (Lichuan 3phase 3NM NEMA23 LCDA357H + LC57H3100)
Questions:
- separate power supplies for each servo? and then one for the parallel port breakout board?
- Spindle VFD, does it need braking resistor for rigid tapping?

- any misc suggestions for improvement?
- Big old capacitors for the power supplies?
