Al The Man : Thank you very much for you help, I will wire in series as you suggest.

Next newbie electronic question. The program I'm using ( Desk CNC ) supports a homing switch. I have over travel on my Retro fited Tree Mill, but never used the homing sequence, as I just make home where wanted on the table. With an open bed CNC lathe , is there any particular advantage to having X and Z axis "home" ?

Again, thanks for the reply.
