There have been a few days more, I have nailed some problems in my circuit and added parameters to EDM protocol generator.
> ... > the important bit is the voltage level of the 'seat' > IF you tune your circuit to track (servo) near this value > THEN the process will stabilize There is a very strong non linearity between: short circuit, machining and open circuit. Then I limited value range to within a small range close to set reference value process became more well behaving then machining. The big question her is how to properly handle shorts and opens? There is a lot of randomness and I guess this is the nature of the process. I expect debris interfere with process. To understand the basics of the dynamics the big question is how seat voltage vary with distance? > > in my experience its near 30Vdc for Cu or Gr to Steel > so my circuits allow the user to choose the traget voltage (near 30 for > the smart operators) > and my circuit finds the ERROR of the real process to the chose target value > That error is fed to drive the motors, My circuit measure voltage in middle of on time if ionization happens and fall back to asynchronously sampled signal then no ionization happened since last measurement. I have set target voltage about to where ionization happens.
