You can probably add an index to the spindle and set up for G76 etc. The motor encoder and belt ratio will give an unusual number of counts per rev, but it's just a number and computers don't care. However, you do need one index per _spindle_ rev to do G76 threading. -- atp If you can't fix it, you don't own it. http://www.ifixit.com/Manifesto ------------------------------------------------------------------------------ Minimize network downtime and maximize team effectiveness.
