    I believe you need to add a line to post. The post im guessing looks as follows


    Infeed # Enable cutter comp
    G1 G41 X[V] Z[H] F[FRate]
    End

    Outfeed # Disable cutter comp
    G1 G40 X[V] Z[H] F[FRate]
    End
    try changing it to look like this

    Infeed # Enable cutter comp
    G1 G41 X[V] Z[H] F[FRate]
    Z[H] F[Plunge]
    End

    Outfeed # Disable cutter comp
    G1 G40 X[V] Z[H] F[FRate]
    Z[H] F[Plunge]
    End


    if this doesnt work you need to add a custom section to your post stating that a Z move is to use the plung rate.

    I think I figured this out in the nc operation if you go to lathe options. You can change the infeed to plunge feed or rapid. Its hard to tell without seeing the file that you are using. But I think this is where change this. The defult is set to feed.
