    hy / maybe you should check the ipw settings and d values, so to speed up the drilling cycle for the okuma

    generally i use long hand drilling codes, because of situations when cycles could not deliver

    I don't see how tuning affects cycle time.
    The trajectory planner could give a poop if the servo follows it or not and it is the guy that controls cycle time.
    Certainly tuning affects how good the cut and your following error is but the control won't slow down for a slow servo loop unless you trip the limits and it stops.
    Have you made a machine cycle faster just by tightening up the servo loop gains?

    hey bob

    here are some posibilities :
    ... editing acceleration + ipw
    ... improving transition between feed movements
    ... interpolation on entire toolpath

    i have messed with values that delivered different time for same toolpath, or make the cnc motion more smooth

    what i dont like is that some parameters can not be changed from code

    onestly, i did not comprehend such functionalities the 1st time i saw them and i owe a lot to veterans



    in the thread about robodrill slowing down near corners, you said that there must be a method to make the control behave old-school i have tried to do the same on a newer control, and i was told to let it go, because increased diff error is equivalent to increased tirr, and speeding arround does not have good effects
