AHH got it Ido have a larger machine.  After the first home activation the drift back to th e Limit/home switch is so subtle that I questioned its doing.  Thank you so much for your help.  I wish I could activate my limit switches for an extra bit of insurance, but like you said if my soft limits and homing are working I really don't need the Limit switches. 
They did work at on time button well.  Thanks again
