    Using the CNCprepro example I tried to design a very simple trajectory:

    If I try to compensate the tool radius using only G41 it display the trajectory correctly:

    If I try to sooth the trajectory using only G51 it display the trajectory correctly:

    If I use at the same time G41 and G51 the behaviour is different depending on the order I use these functions, but in both case looks incorrect to me.
    When G51 precedes G41 the first one it's just ignored:

    When G41 precedes G51 it's just a mess...it seems that the smoothing D value of G51 is used by the G41

    I think there's also an error in the documentation here.
