The really old Andrew machines used a conventional (for the time) RC
relaxation circuit, so I'm not sure why it would be especially good for
cutting diamond. Is this one of the granite-base machines with the moving
head?

Yes. According to Mike, there were three major generations of wire burn
circuits on the Charmilles Andrew machines, the focus of technology at the
time. The machine I have was made just before pulling the Andrew name off
the machine. Again, according to Mike, the next focus was making the burn
circuit more user friendly by computerizing the control of the burn
circuit. This worked, but you actually lost ability to do the tuff stuff
if you knew the machines well.

Interesting. I don't remember what settings were used for diamond -- maybe
it was a high-voltage, short pulse. But don't count on that. It was too long
ago.

Good luck with your machine, Karl. It should be a lot of fun.
