3D Laser Carving with the Smoothieboard
Expensive laser cutters have a 3D engraving mode that varies the laser power as it is etching a design, to create a 3D effect. [Benjamin Alderson] figured this could be replicated on a cheap Chinese laser — so he made his own program called SmoothCarve.
He’s got one of those extra cheap blue-box 40W CO2 lasers you can nab off eBay for around $600-$800, but he’s replaced the control board with a SmoothieBoard as an easy upgrade. He wrote the program in MatLab to analyze a grey scale image and then assign power levels to the different shades of grey. …read more
