This is a story about a guy who started with a $25 set of plans, and through 4 iterations/ rebuilds, ended up with a professional quality CNC plasma table capable of cutting anything steel up to 2 inches thick.

A Torch Height Controller helps improve plasma cut quality and can save a CNC Machine from crashing. This design doesn't require you to know electronics or need any custom circuits... Its plug and play! This is a COMPLETELY standalone controller with a built-in Driver powerful enough to run just about any stepper motor. (maybe a little to powerful for a NEMA17)

Plasma Mill CNC

Inspired by MetalGuru's idea : The plasma too cutter . If you have to cut small to medium sheet of steel with a plasma , this build may be for you

It's a Z floating head idea. Works well. Recommend cleaning the inside of your holes well with Q tips, and polishing the 1/4-20 bolts with car wax and you won't need oil as it slides perfectly. Hope this helps

Fast, inexpensive, near-zero maintenance, and 2+ years of near-daily use.

Not completed yet but it does work, I will be changing small things as I finish the build and I have learned a lot from this build I am looking forward to finishing this one and Building another maybe larger table.

It startet in May with some leftovers from a cnc router build. Now in the middle of December its 99% finish. Everything is lowcost, spend about 1600$ so far.

Inexpensive plasma table. Accurate, fast, and low maintenance.

Improvements to a cnc plasma cutter i designed a while back. Not that it really needs it to work but i think it could be an improvement.
