    I just assembled a new machine and it does not stop either axis when the limit switches are contacted during homing.
    Manually tripping the switches works as expected, hard limit warning is produced and machine stops.
    When using home all the limit switches are ignored and the steppers continue attempting to move the axis until emergency stop is activated.
    What am I missing here?

    Are you sure that the MACHINE is triggering the switches (problem with alignment?)

    Use Troubleshooting tab to test the switches, both a) that they all work and b) each switch is plugged into correct axis (pressing Z switch shouldn't light up X for example)
