    3020 800W watercooling USB CNC axis end limit upgrade

    Hi all,

    I have receive my Chinese CNC some days ago.
    I'd like to add end limit switch on each axis.

    No problem for the switch placement and fixing, but I need you help and ideas on where to wire it on the main board of the controller.

    I guess it's on the Phoenix connector (see attached photos)
    I have slots available named :
    REV / MI1 / MI2 / MI3 / MI4 / Mo1 / +12V.

    Did someone can guide me for the switch wiring ?
    And if possible, on Mach3 settings (or a right link).

    I'll will use a Z prob too, I have buy a cheap molule on Ebay, if any one have information on how to wire it and set it in Mach3, thank you.

    Thank you in advance.
    Regards.
