OK, I think I have a good grasp on G17, G18, G19. The question I have is that according to my test software, it appears that these only work right if I want the arcs to travel straight in the axis, like a channel in the Y axis (G18). If I want that channel to run at an angle, the depth of the cut gets shallow.. This gets worse the further I go toward the 45° mark. Is there a fix to this?
