Star Grounding

I have decided to switch to LinuxCNC from EdingCNC. This weekend I got a Mesa 7i76s (and 7i73 for the pendant); I already had the inductive proximity sensors and Teknic Clearpath motors from before, but I have a lot of reading up to do!

I asked ChatGPT to help me figure out a new grounding scheme, because all of a sudden I need two separate power supplies for the sensors and board, and boy did it come through for me! Where would I be without AI?

Is that an immense porosity supplement?
