How use G5?

Hi everybody,

I need your help. I have the file attached, it is only of G5.2/G5.3 codes. But it don´t work, I suppose that is because G5.2/G5.3 is experimental. I want traduce to G5 codes because I have only cubic b-splines. I have the control points of each splines (see attached file), but I don´t understand how I could traduce it? I read the help of G Codes on LinuxCNC but I don´t understand it, please help me. Thank you.
