Have converted a Bridgeport mill - have three axis working have the spindle going forward and reverse. Hooray. Using Mach3, c11g brake out board, Opto 22 relays, gecko drives. We have pinned the outputs from the pc to the c11g board to run the flood pump, pneumatic speed control, pneumatic brake. But how *&%$ ^ do we connect this to Mach 3 to the output information. Are we suppose to create buttons on Mach 3? If so how do we connect those button to the pin outs.

Frustrated and would like to take the project home. Thanks for any help

Best regards
