S4 if I can't do gcodes to test it, well it just doesn't do me much good. I wouldn't care if it was only good for 10 days just so I could see what it does with one of my designs. I am a commercial user. I have seen the link on the Rhino site as well as another one (which I won't name here in your forum

), well actually I don't remember it either.
Or......if I had someone else to do a gcode from it hmmmmmm.
