You Where saying   
 that 066 si in bas shape si what version should  i download

Ok, well if it is reaching the switch and not triggering an E-Stop then it must be backing off until the switch has again closed. It may just be that the switch is sensitive and you do not physically see the backoff.

You will find 062 here

That is the version i am using right know. some one esle had suggested me that. With that version i can at least ref my x and y but the z not yet.
i tried yesterday to check programing did the set set up again distance travelled. when i shut it down it ask me to save fixtures i said yes. today i will try to ref all to.
My question  today is about the distant traveling back.
the z should you place  -2 in the home off since its travelling away

Can you trigger the limit switch with your finger to verify the limit is in fact working?

One other thing I had to do, was increase the debounce on my system to 250 to allow the switch time to reset during the ref command.
(Not sure is thats the right thing to do, but it allowed the system to work correctly)
