    Is there anything that will cause a problem if I install a stepper driver into the control cabinet but do not always have the 4th axis stepper motor connected to the driver. I would turn the mill off before either conencting or disconnecting the 4th axis stepper motor

    simple question is will it harm the stepper driver if powered up but not stepper motor connected to it ?

    If this is a problem would fitting a switch in the stepper driver power feed be the right resolution ?

    Cheers,
    Paul

    Shouldn't bother the driver, as long as (as you say) you don't disconnect the motor when its actually powered up.

    On my 4th axis, I isolate the mains feed to the servo drive by flicking a circuit breaker to save power etc when not connected. That's a simple and safe way to do it. No point having it powered up and doing nothing.

    If your system requires all axes to be homed before you can use it, you might have an issue. On my Acorn system you can turn off the 4th axis and also disable homing for 4th axis anyway. Similarly, if you have an error / status signal back from the driver to your controller, you'd need to check it wouldn't cause an issue.

    Excellent I will arrange a switch to break the power on the A axis stepper driver. Agee with no point having it power up when most of the time it will not be used
    I think I configure linuxcnc to not home the A axis no switches on it any way
