I just got my copy of PhotoVCarve. Loaded it up in my computer. First try is a head shot of a local singer. Looks great in Photo VCarve. However, when I load it into Mach3, all I get are vertical lines of the same depth. No image has formed. There's no image in the DRO window either. Attached is the image I'm using. B&W with good contrast. My material is level both X and Y. Used default depth with a 1/8" ball nose up-cut bit. Anyone know what I'm doing wrong.
