				upgraded to smooth stepper followed all directions and not the a axis does not respond all others do if I switch back to the port they all move fine.  It is a warp 9 smooth stepper.

				I use my A-axis all the time with both a USB and Ethernet SmoothStepper. Take a look at your configuration in the SmoothStepper configuration section. I've also had Mach do funny things at times when I 'cloned' a profile. I've seen various Ports/Pins just not work with the cloned profile. Starting a new profile from Scratch did the trick.
