Hello All,
We can stop this thread now.
After re-checking the wiring and going out and buying much needed test
equipment and talking to a couple of guys from this group...MY PROBLEM IS
SOLVED!!!!!
It was my cable...it was NOT a through cable and now everything works

BTW...watch out for VELOCITY...WOW!!! talk about FAST.
No for the limit switches...GRIN
Thanks again, Robin
