    Default CNC is not running Dynamic Optirough properly

    I have been programming mainly 2D for a couple of years now. For the past couple of months i have been programming and running more complex aluminum parts. Every once in awhile when i use Dynamic Optirough on mastercam x9 I run into this annoying problem where my cnc decides to randomly and unpredictably finish an arc and come full circle and then continue on its original programmed root. I have verified my g-codes over and over and i see no problem.

    Check your IJK mode. I don't remember the exact name in MasterCAM, but there is a parameter for that. I went through this a while back.

    The arc center type is "delta start to center" for XY, XZ and YZ plane. Should i change it to radius?

    Don't change it to radius unless your machine can digest that, older CNC controllers normally don't use radius. You are in the right area, there are a few other options there. Try a different one and see what happens. I just did it with trial & error, I don't remember what one worked for me. You should be able to see the result if your machine has a tool path graphic.

    The issue is you have your CAM program set to use Absolute moves when doing curves/arcs when you set it to incremental moves for Arc and the problem will be gone

    Hi.
    If your post generate arcs with
    G3 X Y R than try to change, if possibly, to G3 X Y I J. In my case i never get problems with arcs again.

    I do not think incremental/absolute arcs would make a difference. I think you would need to go into the Control Def > arcs > check 360 degree arcs > check break arcs 180 or at quadrant, what ever your machine can handle..

    What is the machine you are programing for and how are settings in the transitions in the linking of the opti rough.
