Actually I'm almost certain that the distance between index pulses is more like 0.2" on Dave's machine. He said that index-enable went high, but didn't say anything about it going low again. That sounds like it isn't getting the index pulse. I can't dig deeper at the moment, but if Dave could post the halscope traces to imagebin or somewhere, it would help diagnose the issue.
