So am I. For a little more detail I ran a grounding wire on a mounting bolt for each of the stepper motors (read here that the wheels act as isolators, cant' fault that logic so ground each one of those) My table is aluminum on plastic wheels, so grounded the chassis. Also ran a wire inside of a static dissipative vacuum hose. This all went to a grounding bar. Then into a outlet with only ground hooked up (more convenient) Ran a 6 hour cut on Sunday with no problems! Still one issue (LOL), the non-static hose I bought is 2 1/2". This basically killed my suction. So thinking about going back to the 1 1/2" hose, and wrap wire on the outside. No dust control is a no-go in the wife's garage!
