PhotoVCarve is a pretty simple 4 step process. First you import your photo. In step 2 you set the material size you want, the XY origin, material thickness, and units (mm or inches). Step 3 sets the cutting parameters: bit, max depth of cut, line spacing, line angle, gives you the option to invert light / dark areas (for lithophanes) and calculate which gives you a preview. In the final Step 4 you can preview in various materials, see estimated machining time and save your tool paths.+2
