Thanks for your reply. However, as oft times happens with me, I was not clear enough. Z is first and it goes to the limit, but does not back off the switch. Then Y goes to the limit and does not back off the switch. Then X does the same. When X hits the switch. The reset come on with the tripped limit. Now, I have to back off each axis by overriding the limits or turn off power and do it manually. The problem is that it doesn't back off the switches.
Any other thoughts??
Thanks again for your reply.
