Are you using the switch as a pure limit switch or as a home switch? If it
is just as a limit switch which only trips when the machine has travelled
too far - that is, as a safety device, then you will have to use the
'override limits' button to get the axis to move again. However, if you are
using the switch as a home switch to place the axis at a precise position
from which to start machining, then there is a setting in the .ini file
which makes the machine move away from the switch automatically. I can't
remember just now what the setting is called as I am not near my EMC
computer but its intention is to allow you to home all three axes even
though you have to connect the switches in series under EMC. The action is
that the axis travels along until the switch is tripped and then it
(usually) reverses direction and backs away by a few steps until the switch
closes (or opens) again when it then stops. This is then your effective home
position from which machining can be started.

Best wishes,
Ian
