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. 

Regards, Doug
