I started How onidea showed it from the motor to the filter to the ground. I added the pipe of course. but I felt some shocks from the frame sop I screwed into that. it helped but still some light shocks. I also got it on the lid of the can so I grounded the hole the can lid too and now nothing zaps. humidity is pretty low in my shop 32% so maybe that's why it is so bad.

Those connections don't look like they are soldered. Are they?

The connections are sloppy, but there is no reason to solder them. Just clean them up.

I don't think static really cares if it's sloppy or looks pretty

no not soldered but well twisted. it was strange I had the frame with a screw in it I was still getting lightly zapped till I ground the can lid too. now none of it shocks me. I have that big drain pipe right next to the machine nice and handy.

Copper will tarnish easily and corrosion adds resistance to the connection. Soldering or using twist caps can preserve the low resistance connection. Electricity will always seek the lowest resistance path and if that's through the circuitry of your steppers, then that's where it's going to go.

Thanks for the reminder of tarnish John.
I was just vacuuming behind the machine yesterday after emptying the steel canister of the little Oneida DustDeputy, and felt my arm hairs rise from the hose.
rechecked my twist connections and one had loosened and was almost off. Re-twisted and all gone:)
MAY have caused the first Spacebar Pause/Resume crash I've had in YEARS a month ago.
Static season is almost here after a very humid Summer here.

Here in NE Washington, it's tolerable in the summer but REALLY dry in the winter. I have to have a humidifier running all winter to keep RH around 35-40%. So HF radio level grounding is an absolute MUST here otherwise I'd spend my days chasing down lost comm issues instead of making money.
