If the math showed only 7 milliVolts, twould be a different matter entirely. But FOUR VOLTS trashes any conventional logic system, even with hysteresis. | |

Furthermore, you were right about the frequency, 300kHz would be too much. I mixed up the step frequency and the motor driver's output frequency, which is by far lower due to microstepping. I'll edit the question accordingly. | |
