limit switches

Hi from Australia,

I am building a milling machine with gecko drives
and CNC PRO. So far I have everything up and running but I am having
lots of trouble finding a difinitive limit switch wiring diagram.
Being a poor dumb hammer user i wouldn't know what a pull up resistor
was if you stapled it to a trout and beat me about the head and upper
body with it. I would be really really really thankful to any one
who could help me solve this problem. I love this discussion group
and have learnt a lot from following the posts

THANX>>>
