I was thinking of connecting ground from jackpot to a some metal elements like you see sometimes in an electric box (like on picture) I thought it might help to discharge any unwanted charge.
I’m not an electrician
dust extraction creates a CRAZY amount of STATIC, you would ground only ONE side.
There are details somewhere here on our forum.
Ugh. There’s a methodology for grounding.
For enclosures, what @jeffeb3 said is correct. Best practice is to ground your metal enclosures to AC ground (at the source!)
DO NOT ground your static dissipation to your power supply DC returns (e.g. the jakpot ground). That’s just simply wrong and begs to crash your job or break your electronics.
DO NOT ground your dust collection “at one end”. Tie your static dissipative elements back to the source AC ground.
That’s a nice enclosure, though I bet it isn’t yours; there’s no Jackpot in there. Yes, that box ties the cover to the body through that jumper wire. Enclosures are grounded to AC grounds.
I have the same problem with my new Jackpot3 board. All my testing and moving the machine the probe worked as expected. Ran a few small jobs to cut holes in the new spoilboard then a longer job to cut the Matchfit relief cuts. Switched to the Matchfit dovetail bit and probe state errors. Only thing that worked was changing to pin 39. The dust hose is grounded and there is nothing I can see wrong with the top or bottom of the board when I took it out. I hope it does not happen on the 39 pins as well.

That’s a bummer. Your reply is to a topic that has 11 months since last reply, many folks will not see it. I advise you to make a new topic so we can get more eyeballs on your issue.
That seems to indicate a GPIO issue, but more troubleshooting to do.
If you run $Limits with you setup in the FluidNC terminal, how repeatable are your Z probe actions? If you cycle it 30 times, does it give you 30 straight correct sense responses?
On your probe setup, is the clamp part on the ground line and the plate is on the signal?
Hej. Thanks for the reply. I try not to make new topics when I find one that is relevant, but I suppose 11 months is a while. After running a surfacing routine today, I am getting the same probe issue on pin 39. Cannot get it to clear, no matter what I do. Yes, the clamp side is on the ground pin and the plate is on the positive pin.
Ahhh, around here a new one is always better. There is so much going on and things move very fast. New with current info is just easier for all of us than reading through old stuff wondering what has changed.
