    im using DIR (pin 8) to control the Spindlev3 boards Relay, and STEP(pin 7) to control the 0-10v dc from the Spindlev3 board to the Gemini board...

    This picture shows you using pin 7 & 8 to get a voltage

    So you cannot use pin 8 to turn on the relay

    Just to clarify, do you have an additional relay for controlling the spindle on/off?

    i normally use pin 1 for the speed signal and pin 14 for the spindle go.

    Pin 7 should be getting used to produce the voltage, via the Step terminal on the V3, and Pin 8 should be controlling the relay on the V3 via the Dir terminal.
    You should then be using another pin to another relay to turn the spindle on/off.

    i'm sure there's an enable on the gemini, you can use the second relay to control it.

    one point worth mentioning, the control of the contactors is 240v mains. This can cause a lot of noise, so it may be worthwhile having a low power relay that is switched by the v3 relay sited by the contactors to switch the contactor.

    This way you don't have mains on the v3 board.

    this was the aim, i am gonna sort out another relay to turn the spindle on/off.

    ive got a mulitmeter zapping out the relay contacts NC and C, its showing closed circuit, when i press "spindle" the BOB lights do something but should the relay switch over to NO and C? this creating an open circuit and the multimeter show nothing at all

    they way to check is:

    put your meter on continuity and the neg lead on the c connection and the pos on the nc and the buzzer should sound. Then get mach to switch the spindle on and the connection will be broke and the buzzer will go off. With the spindle off move the pos lead to the no connection and the buzzer will be off, then activate the spindle and the buzzer should sound.
