Gantry have to be grounded to frame on Plasma otherwise you can weld the Hiwin balls together

I believe that is correct to connect gantry to machine body whatever the machine, to avoid that bearing fault, it had its own name, but i forgot it...

Yes to the machine frame but not back to the Star point. Only one Earth cable should go back to this point.! Scott is runnig separate cables back to the Star point which Can/does create Earth loop.!
