Grounding a CNC Router
From contributor J:
Metal pipe on the dc.
From contributor A:
Ground the machine and that will eliminate the shocks. Also, you do not want the current running through your computer that runs the machine, which could be very costly. I would call the manufacturer and ask where the best place is to add a grounding cable to your machine.
From contributor M:
We had the same problem. We checked the metal frame for current and had a few volts running through it. Just take a volt meter and touch it to a good ground and find bare metal on your frame to see if it has voltage. All you do is get a 6 foot ground rod, drill a hole in your concrete floor, drive the rod into the earth, add ground wire to a bare spot on the router, and it gets rid of the wild voltage. Also, my electrician told me to make the hole in the slab a little bigger, so in the extra dry months I can add a little water in the holes to make the ground damp. He said the damper it stays, the better the ground.
From the original questioner:
Thanks. I'm installing a grounding rod now.
