So which is it? Connect Gnd to 0VDC, or not? I've pulled apart quite a lot of industrial plotters, printers and I've Never seen 0VDC connected to Gnd. Same with robots, Injection moulding machines. All frame metal parts are quite interconnected, sure, and Grounded, but all electronics has it's own power system. I don't understand the desire to connect two lines together because they 'seem' to be of the same magnitude. 0VDC is Not equal to Gnd Many systems will have multiple 5V power lines, heavy, light, designated. Do you want to link all those up too?
