    optical limit for x2

    How does Industrial hobbies use one optical limit for Home and bot limits? Where would I found a switch like that? I know the digikey switch was talked about but that is only one sensor. It would be nice to have an IH similar setup.

    The switch has a trigger bar that can activate from either side. So for example on your X axis you would mount the switch itself on the XY saddle and two stops one towards each end of the table (such that they activate the switch at the appropriate point).
    Then EMC2 allows you to specify that the limit switch(s) and home switch are shared.

    There are two switches side by side, here is a close-up of the ones that I am making. Using digikey part
