Hello everyone. I have long been in this forum but never write.
I recently built a plasma cutting machine and seems to fit well.
The problem I have is that I need THC and see are very expensive for me. I'm looking at the circuit of thc leading Mach3's instructions, but do not quite understand.
Anyone have data on that circuit? or know how it works?
If so I would make the circuit for my machine: Here I leave a picture of this.
