The shield ground is to be connected at one end only with the other end left not connected to anything. ?This means there can never be current flowing in the shield. ? ? Connect the shield to the Lathe¡¯s DC ground point.

The LMS lathe DRO kit has DRO reader heads with the coax cable shield tinned, presumably for grounding. My AC Panel is grounded to my copper cold water pipe (meets NH code), with both in the basement near my lathe. I can tie the DRO reader head coax shield into the same common ground. My LMS4200 lathe is electrically grounded via a screw into the headstock, with the lathe power cable plugged into AC mains. WIll this be sufficient to ground the lathe & DRO?
I¡¯m pretty good with Ham Radio grounding to avoid group loops (I have a lot of copper rods in the earth, all tied to my AC panel) but don¡¯t know the norm for DROs & lathes/mills.
