Hi all ,.
I am having a few problems with my new to me smooth stepper ..
I am running win7 pro. its the not the usb version.
 I get the message the ess did not respond to wake up message .
Any ideas . I am trying to get this to work so as I can replace my existing computer 

Sorry for all the questions but...

Which version of Mach3 are you using ?
Which version of the ESS plugin are you using ?
Did you use the SCU to set it all up ?
Is the top green LED blinking twice per second ?
Are you using a separate PSU for the ESS power ?
