| Jan 15, 2019 at 7:34 | comment | added | garyM | I'm attempting to figure this out. I'm rethinking the modalities, more specifically modulating torque to make the dial easier to turn and detect induced voltages. Microstep drivers/motors inconsistently induce voltages based on micropositions and big step rotation due to stepper manufacturing variation. I'm not doing any machine learning for a movement detector ... Now I know why no one has done this yet | |

| Jan 10, 2019 at 19:32 | comment | added | garyM | I haven't selected the drivers yet. I think I'll be using a STI's L6400 series part. I was really hoping to find someone who's solved this problem in the past, I didn't want this to turn into a science project. Detecting tiny induced voltages on a driven stepper is a non-trivial task. The more I'm searching, the more it's looking like a "green field". | |
