We have an older Milacron 850 and a Hurco Hawk and are having issues trying to get them to read .nc and .hnc posted from Fusion 360, I can have my wife create a macro to convert posts to read in the older tech. My question is, would these macro's be worth trying to market to other folks that have similar older machines. I've seen that CNC XChange converts from different brands/types of up-to-date codes, but I haven't found any that convert backwards.
