Clint - my Tsugami lathe is similar, except it had a 3phase AC motor with hi and lo gearing for rotation - but did include the binary cams (position, top-dead center and a PARITY bit!) - although that setup did prove to be less-than-optimal in the long run (I have since converted the turret over to direct drive servo) - and am writing a component to handle the position offsets and auto-homing procedures more cleanly. My earlier CL work, which required two ladders (one for the turret operation and a second as a lookup table for conversions), is still posted at the Tsugami blog: www.casafrog.com/cfblog -- you're welcome to borrow whatever useful tidbits you find there.
