So this is just a working thought right now. I have a Northern Hydraulics 375 model 40 amp plasma cutter and I would like to be able to do some small projects with CNC control. I suspect that my little 375 is not ideal, but as often as I do plasma cutting it is not worth it to buy a more expensive machine.
So rather than attempting a complete CNC controlled torch, my thought was to just make a mounting bracket with and old fashioned boden cable remote trigger control. My CNC table runs off MACH3 and I use V Carve for creating all my designs. A modified PP to add a dwell after the Z movement to get the arc started and then your off and cutting.
Is there any reason why this could not work?
