Hi Richard, I'm not in the board business but have worked on a routing machine in another entirely different line of work. Does the machine have a vacuum hose for pickup? That's a great place for ESD to build up on a NON-conductive surface, i.e. no bleed off until it discharges all at once. We had to run a bare 12 AWG wire from end to end down the inside of the vacuum hose.
