LithoGrave Lite 1.0 is available as a free download on our software library. The program relates to Photo & Graphics Tools. The actual developer of the program is Pro Design Lab.
From the developer:
LithoGrave Lite is a simple, easy to use program that converts BMP images to basic cnc gcode. It is optimized to produce gcode to engrave only lithophanes in Dupont's Corian and similar materials. The produced gcode is compatible with Mach3 and TurboCNC, as well as other cnc control programs.
LGLite is not an image to vector converter. It only produces gcode for raster engraving.
