Thanks for watching! Please send me any questions or comments you may have to improve this DIY CNC Plasma Cutter.

This was a fun project. I basically just converted a cheep laser engraver used for hobbies and strapped on a plasma cutter creating a simple home purpose plasma CNC cutter. Total money I spent just over 300$ for the laser engraver and the plasma cutter. I used some scrap metal to make the cutting table which served two purposes: this made a proper cutting surface and raised the cutting surface closer to the plasma head. This was needed to gain clearance where the plasma torch will not interfere with the engraver frame.

Wiring:

I could have spent more time figuring out the relay system. From what I understand, If I move the engraver driver further away from the plasma cutter head, this will decrease the amount of electrical signal interference. Also adding wiring shielding would help with this. All in all, I think the thumb button was the easiest way to go about this.

Momentary on switch or "mom" switch

CAD Software:
Laser GRBL: worked just fine for the simple stuff

Light Burn: This is a product for purchase. the software license is 89.00. They offer a 30 day free trial which is what I used to make everything in this video. I will purchase this if I don't go with the fusion 360 program.
