Re: Perfect Homing Accuracy

Randy,

I'am retrofiting an old cnc mill (Schaffner Swiss Made ) , I'am
cutting Steel , Aluminum ... making Blow molds , I have to make it
very accurate since I may not finish all the machining passes in one
day and I have to home accuartly so as I can finish the rest of the
machining the next day.
