    Need to reset twice after hitting a limit switch.

    If I have Soft Limits turned off and hit a limit switch it triggers an E-Stop,
    as it should. Using manual over ride I can jog off the switch but as soon as the
    axis moves a fraction of an inch and the limit switch closes, it triggers
    another E-stop. I then have to hit Reset again, and then can move away as normal. Is this double limit switch triggering of an E-Stop normal? Or is there a setting I've missed?

    Increase the debounce to 500. Are you using mechanical limit switches?
    They can bounce on transition and retrigger the E-S

    Best way to fix this is make the soft limits work correctly, then there will be no problems.

    E-S is EMERGENCY STOP. Use it for emergencies, as it was intended.
