GROUNDING A CNC PLASMA TABLE PLUS A LOOK INSIDE THE CONTROL CABINET

This video is to help a member in the Masso club to get his CNC plasma table working.
It shows grounding of all components and what i have done inside the control box.

Hi Ross thanks for sharing your videos, EMI has to be one of the devils tools when it comes to electronics and we all need to do as much as we can to eliminate and insulate from it and you have pointed out some helpful and positive ways to do just that. I am just glad I don't have anything Plasma on my CNC router cheers Bill

Well Bill, if you like thumping your head against a wall about EMI. I would advise you to try giving plasma ago. No joking I've got my fare share of bumps on my head.🥴

Awesome job Ross!

Thanks for the reply, I did this video to help a fellow cnc plasma guy, He has a table that breaks all the rules, just hope he learns from this video.

@@rosswoolley2854 You're a good man. I'm planning on building a CNC Plasma table soon, so I'll be watching all your vids(again) for some inspiration.

@@n8o8n Can you build a full size table, reason being a full sheet is always cheaper and it gives you more opportunity if you need to cut privacy screens, or even a life size 👣Big Foot👣

good to see someone else running their plasma with a masso. have you figured out how to make the torch turn on and off automatically when using feed hold?

[@rosswoolley2854]

No i haven't Chris, I close to never get a crash and lets say if it did you press start to line and it will start from the last Pierce. just up the thc a bit say from 124 to 147 and it should be OK. I only use feed hold if i want to remove a flip up after a cut, remove the flip up then press start to continue to the next part to cut. Thanks for becoming a subscriber.

What would emi cause I built a table a while back and every one in a while it will not fire the torch for one line and the next line it will come back

[@rosswoolley2854]

I basically covered every thing in this video for grounding. The only thing i didn't mention was i pour water down the hole next to the ground rod. Plus all the wiring is double shielded and conned to the bus bar of the cabinet and run to the table leg with heavy gauge speaker wire. If that is all done and you still have problems you would be best having a second ground rod next to the cabinet.
