    Peck Drilling in Bobcad 24

    I just upgraded to Bob 24 two weeks ago. All has been fine until today. I have lost the peck drilling cycle. I select peck drilling in the hole wizard and I get the G81 command instead of the G83. Here is the post I have been useing. Please help.

    The peck drilling is overrided by the material file. Here is the code I generated using your post.... You will notice a G83 is present. You probably need to change your cutting conditions to allow the peck to work.
    If you would like give me a call 727-489-0003.

    Thanks for your reply.

    I started a new file and the peck drill cycle worked fine.

    I do have a new question:

    What is the post variable for the initial peck move? There is an entry for it but I don't see a way to use it.
