That would only work if, prior to switching off, the stepper would have to be driven to position 0. That is what I did.
Or to store the last measured analogue voltage in an EEPROM position. Is that what you mean? As I used this machinery to adjust a high-voltage capacitor to the resonance position, I did not think about that yet.
