I’m fairly confident that I’m experiencing static due to the dry air this winter and the dust collector. I’ve blown the front fuse on the controller and recently experienced a scary screen (think of the famous Matrix scene) crash, followed by minor settings corruption for the spindle. This is a large DC and the hose is not anti-static, that I’m aware of.
I watched the MASSO suggested ground loop video (and others in that series).
Would be appreciative is anyone has first-hand success experience.
If I replace the trunk of the hose attached to the CNC with an anti-static hose, that should be sufficient in preventing static build up near the CNC, as well as conducting any static through that hose, correct?
I’ve read about running a wire inside the hose and ground it to a receptacle, so that’s a possibility, I guess.
I’m terrible at making use of reddit. I have an antistatic hose due in today. Will see how that goes. I wouldn’t mind investigating the potential of measuring/monitoring static surges to quantify and prove success.
You’ll need to make sure the hose itself is grounded. If it is attached directly to your DC and the DC is grounded, you should be okay. If you have something in between (like a cyclone) that is not conductive, the static will just build up in the hose and you will still get zapped. You can wrap a bare copper wire around any part of the antistatic hose and connect the other end of the wire to something grounded.
That sounds close to what I’m thinking. I now realize that no amount of grounding or wrapped wire outside a PVC hose will work, but the antistatic hoses, from what I can tell, are partially conductive, allowing for grounding. I’ll address the CNC first and then, if successful, take on the other hoses. I hate to replace them all, but I’ve even seen LED lights flicker while planing! Wouldn’t you know, I accidentally ordered a 4" hose last night. Had to reorder the 2.5. Doh.
