I am in the process of retrofitting a Precix 9100 R&P cnc router. It has nema 34 servo's with 8 wire encoders.

I have attached my partial wiring diagram for the machine. I don't show spindle control, limit switched, or e-stops yet. I am planning on having everything inside of a large wood box, so I was going to use a grounding bus bar for a chassis ground.

Does all of this look correct? I was not sure about some of the grounding as the PDMX manual gets a little confusing for me in that area.

Any help would be great
