I found that program just let send me an email at
ken.moran@smi4motion.com and I'll attach it to a reply. The compressed zip file is only 338kb. But, the others are correct you will need to edit the Z portion of the G codes to get a 3D effect. May take some trial and error but should be able to get it done with the Mach 3 program from what I have seen. Also I have never tried this program I just stumbled across it while looking for something else.
