    Default looping program for lathe with bar puller

    OK I tried a few different avenues and am having trouble getting the right code, or at least written correctly maybe. I got the program to behave properly using repeat. Downside for me is no piece counter for me to know how far along in the program I am. I determined that I can get 85 widgets out of the chunk of stock with enough material left for the collet to hold + safety margin.
    I got it to run using this code with the idea of using the B m99 counter as my current run counter. The problem I encountered with it is the counter does not increment every time. For 37 pieces the counter went up 16. This leads me to believe I have coded it incorrectly but am stuck figuring out why.

    Default Re: looping program for lathe with bar puller

    The only way I could have a part counter to work on the lathe is by using a digital counter plugged to the USB relay board.

    I already use the USB relay board for the collet closer.

    I just use one of the relays to send a pulse to the counter. I know this is not what you really want to do but it works for me.
