Hi Matt, could you tell me what kind of STG board you are currently running?
I just implemented index-pulsed homing for a STG1 (blindly, as I'm away from my devel box, and STG card), but I was wondering if you could take a shot at it. Contact me for more details how to test it. The code is in the latest HEAD, and I'd want to backport it to 2.1 once it's properly working (if that is true before 2.1.0 is released).
