This is easily do-able in a $ 1.20 CPLD A divider would work well, but I'm no programmer and wouldn't know where to start. If I can't find a simple solution it looks like I'll have to get another encoder. >Would you need the index at high speeds? My normal working range is 600-1200 rpm. Most of my threading is done at 600-1000 rpm, depending on pitch.
