Default Reducing Static from Dust Collection

Guys...
Put together a short Video showing a few tips to help eliminate static "gremlins" from CNC machines that have a dust collector attached to them.

Hmmm, I have all those bases covered except keeping the hose itself isolated from the machine. I’ll have to rethink that.

Thanks for another enlightening video.

A half inch is all it takes. Less than that and you can see static arcing

For my hose, on the last foot by the machine I couple on some static-control hose. It doesn't bend well, but it does what it says. I tape a wire to it and connect it to ground. I notice the (huge) difference when I pull the hose off to use with a orbital sander.

I think I have some 1/8” G-10 sheet that should make a good insulator between the hose and the aluminum support plate.

Thanks for the good and timely info, Gary. The heat is now officially on in my shop and I will be using this info to check and double check my grounding of the dust collection system.

We just had a weird gremlin in our router spindle. It would randomly drop speed for a bit, then pick up again. WinCNC showed no change, but it was clearly audible.

Called tech support, they told us to ground the dust collector. Havnt had an issue since. Moral of the story is ground your DC people!
