hy joemach i never tried G15 H=variable, even when working with multiple wsc, but i believe you that it may not work i also searched for vsoft, but i could not find any details on it
however, is possible to use multiple the origins, even if G15 is used only once inside the program
i believe there are multiple fixtures, and you wish to restart after a random interruption ? please, in order to give a specific solution, i need more details on your setup / kindly
