    I have an old program from a TW20 that has a cutoff op in it. But I'm not sure what you want. Do you want me to type up the relevant parts with the wait codes?

    Hi extanker59

    Any help at all would be appreciated. At the moment we are unsure how to get the sub-spindle across and the catcher in position to catch the part.

    Regards
