Grounding question

[IPGregory]

Probably over thinking this, but...

If I have a supply cord to my machine with a ground in it and the Acorn is connected to that ground. Then I have a separate supply cord to the CNC PC, also with a ground. Both go back to the consumer panel, but to different breakers.

When I connect the shielded ENet cable between the CNC PC and the Acorn, doesn't that create a ground loop back to the panel?

I have confirmed the Acorn RJ-45 connector is connected to V- and the CNC PC is also connected to V-. Should/can I remove the shielded RJ-45 connector at one end of the RJ-45 cable and replace it with a non-shielded one?

Or is this a non-issue?
