    I have done the "mechanical work" on a milling machine table to provide two axis control!
    I am now considering the electrics/ electronics!

    Do I need to incorporate limit switches or can I limit the motions in the software ?

    If you hit a limit switch you have already blown it, fairly useless.

    OTOH homing switches are really useful if you are cutting with jigs.

    Depending on the software/hardware combination you use the Home switches also work as Limit switches after the Homing procedure is complete.

    Agreed, I've not bothered with them on mine. I always zero the existing dials before starting off, and check the travel is ok, so if the worst happens I can get it back.

    If you are using servos then you definitely should have them.

    or Yes I can set the travels limits in software.

    I presume I can also set home in software!!

    If I were to fit home switches I may as well fit the "away" switches too
    Is it permissible to leave switches until I get the software set up or am I likely to crash into end stops.
