    Default Hardinge bar feeder interface

    Hello all, I'm in the process of interfacing an SMW Spacesaver bar feeder to a Hardinge conquest 42 lathe. The lathe has a Fanuc OT control.
    I have most of the manuals but very little info regarding bar feeder interface.
    So far I've managed to get the bar feeder to feed from the collet open signal, but now I realize that I need an M finish signal to tell the lathe to close the collet. I only have 2 sec after bar feeder stops pushing before bf alarms, so I don't think programming a dwell between collet open/close is going to work.

    Starting to get some pressure to get this going.

    Does anyone have any experience with this setup?

    I need to find a place to input a 24V M finish signal to close the collet.
