Re: [CAD_CAM_EDM_DRO] "Light Bulb" EDM ???

I've built it, it works but VERY slowly. I would only
use it again after eliminating all possible mechanical
solutions.

The light bulbs are to limit peak current (they are in
series). I posted the plans to one of the Yahoo
groups last year, I don't remember which and I no
longer have them on my drive.
