Re: [CAD_CAM_EDM_DRO] G02 - G03

From what I understand, most controllers either use R or IJK, If the IJK
values are not correct then the controller
will ( or should) report "End Radius not equal to Start Radius".
To me , this makes it rather silly to use IJK, why not just use R, that
way it should always be correct as long as R is with-in a window of
tolerance allowing it to touch both start and stop points when swung. I
guess R would have to be at least 1/2 of the distance between start and end
and any distance long. Does that sound right??
