I'm putting components into my electrical cabinet now and am thinking about electrical ground wiring. It's possible I'm not considering something but the schematic for the acorn board only has a ground connection between the power supply and the board itself. Is this intended to be the ground for all of the components connected to the acorn board? Should I add additional grounds?
As a side note, I do have a second power supply with a ground specifically to power my axis motors and another AC ground for my spindle motor.
Should I add additional electrical grounds?

Re: Should I add additional electrical grounds?
Your drives, the power supply for your drives, and your VFD should all be grounded as well.

I have CDO. It's like OCD, but the letters are where they should be.

Re: Should I add additional electrical grounds?
The wire gauge for the protective (safety) earth should be at least as fat as the incoming mains wires. And the fuse / circuit breakers should be low enough current to protect the wiring. All the components that have mains voltages in them should have a protective earth.
