Low budget plasma setup, what do I need?

Not decided yet what kind of sensor to use but I will keep that in mind.

Two new parts ready, Z axis wedge arrangement. Still some tweaking to do on the white part.

My cheap chinese Z axis is a piece of $#^*. I had thought of doing a 3D printed float assembly but I think I'll keep an eye on how this pans out, it look very interesting.

In due time you will see my contraption in action, a bit slow progress for this 70 years old fart

Some progress to parts for Z axis

Looking good.

this is quite a very hard build on dusty Plasma
the Clamp(i hope i get it right it is the clamp)to torch inside a fixed is by far not good
it will head up the system
and as we use 5Plasmas in shop i can tell you as more material is around the torch it will produces EMI to the complete system over long distance

keep the torch off by at least 10cm to the machine frame

Next in line to be printed

I think you might find that you will have to move the torch down in the holder as it will get quite warm at the business end
