I’ve been having issues with static build up lately. I thought I read somewhere you could run a 12g copper wire on the outside of the vacuum hose, and plug it into a grounded outlet with a plug, but not use the power side of the plug just the ground. Is this correct I use a DEWALT 5 Gallon STEALTHSONIC Shop Vacuum Wet and Dry. Or what should I do about the static build up with the equipment I have.
For reference.
Machine is a DYI built machine all aluminum (Looks like a openbuild leads)
Dewalt spindle
Openbuilds controller and interface
I bought an electrical plug, some cheap ( maybe 24 Ga) uncoated copper wire., and a grounding buss. I ran the wire inside my vacuum hose, out, and back to the grounding bar. I ran a strand of wire to the ground on the plug and plugged it into the same circuit as my machine. I then used a multimeter to ascertain other parts of the machine were grounded. They were not. I ran wire to ground everything except for the trim router. I used to not be able to cut plastic. Now I can. The ground bar is the key to avoiding ground loops. Try it. It’s a very cheap solution. Use the magnifying glass tool at the top of the page to search “Static”. You will find some brilliantly detailed solutions.
Good read. I’m just not good at wiring and figuring that whole thing out. I did figure out i need to earth my machine piece by piece. Z access to Gantry, to the frame. But unsure what to do with it afterwards from the fram. Sill not really sure about the static on the vac hose yet still reading.
Well…you are going to see in the photos that I am not good at it either. But what I did is adequate. Note the copper wire INSIDE the dust hose. I ran it out maybe ten feet toward my stealthsonic vac (which I keep a good distance from the CNC and poked it right out the side of the hose. (I taped up the wound), then back to the buss…which you see in another photo. All other points are also grounded to the buss. Then, only ONE wire goes to the ground plug in the same circuit as my CNC (which is dedicated)
