mills ,try heidenhein web site for more
m codes you need most are m3,4,5, spindle start cw- ccw- stop & m25 -spindle stop/z retract, cutter comp RR & RL right/left os.Rads are CC circle ctr CE circle end. cycl def button gives cann cycles.And thats about it the rest is simple co-ord programming.hope this helps
