have a avid cnc machine with ethernet smooth stepper running mach3 and uses the avid breakout boards.
A coworker who is no longer with us installed a ribbon cable in the port 3 of the ESS and the ribbon cable goes to a seperate board that then allows you to connect regular panel wiring to pins you choose.
He used the port3 to control a stepper/servo motor. could someone explain how he may have set up the machine to use port3 to send the pulse and directions to the motor that he mounted for a spindle?
Is then in Mach3, or something you have to setup in the ESS?   Thanks for any assistance, have not messed with this in a couple of years.
