Whats on the heat sink on right.? Looks like thermister, resistors and black box which I'm not sure about.! And what are they doing.?
What and where's the power source.? ie voltage.
Where did you get the peristaltic pump.?

Not really a heat sink, just a packer. underneath is an SSR to control the air valve, the square with a red blob is a 12v lamp-flasher which gives me the pulses, next to it is a 12v reg. (with a couple of ceramic capacitors ) needed because I am supplying 24 volts from my main panel. The AUTO mode is an M7 relay in the panel.

Thanks John I got the Jist of what would be needed to make this work from pic and the Reg I recognised but it was the Blackbox with what looked like a Thermister above it that thru me off.! . . . . . Now I look again can see it's part of the black box.!

That with the pulsing seems a great idea. I missed that.

I didn't mention the round black item - this is just a small air reservoir mounted directly on the air valve, (bigger would be better but its what I had lying about) it gives a bit more bite to the pulses and dampens the air gauge a little.

Just a note about my vision of the correct flow shape. I would like to illustrate how i like it. See photo below.

I maxed the cooling supply so its more clear whats happening. When milling aluminum you can barely see the coolant flow. When nozzle properly made /IMO/ the overall "flame" shape is long and concentrated and in the middle forms a very nice thicker stream, it basically sounds like a nice small propane turbo burner . No mist at all. You hit a wall with this stream and it all goes down, nothing up in the air.

that stream bellow is should be enough even for engraving stone and soon i will try it when i have my machine ready :-)
