Hi Hood,
I have Cool Air, Mist, Flood, Light, Hold downs controlled by two relays etc. On my other system CNC4 I issued a M94 code in my g-code to close my relays. Example: if the light was connected to Relay 4 In my code I would issue a M94/4 and it would turn on the light. Mach3 does not support the command M94 - so what command do I was to close relays 4-9? I am a electronics engineer, the relays are wired correctly.
