Jeff,
  the machine has movement in test mode. mach 3 shows movement, but no table movement. with my limited knowledge I am trying to figure out how to configure a pmdx-126 board properly for my Ethernenet smooth stepper. any advise to point me in that direction would help greatly. I have read what i have found on it but have not figured it out at this point. Thanks for your help!

There are only a few jumpers on the ESS and PMDX-126 that you need to mess with if you are wanting to power the ESS form the PMDX-126 or vise versa. The PMDX-126 manual covers this in great detail.
