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:

1. removing all motion controls & replacing with new
2. removing VDF to replace with new.
3. possibly removing spindle motor to replace with more powerful unit
4. have to place rotary encoder on new spindle motor for rigid tapping
5. 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:

1. separate power supplies for each servo? and then one for the parallel port breakout board?
2. Spindle VFD, does it need braking resistor for rigid tapping?
3. [link https://www.amazon.com/dp/B0093Y897A...CGSMRB2V4Q]two sain smart parallel port cnc breakout boards[/link] or go with an [link ethernet]7I76E picture card like the Mesa 7I76E[/link]
4. any misc suggestions for improvement?
5. Big old capacitors for the power supplies?
