Sorry I misunderstood you. It's all in the software used to run it. I use vector art, but you can use grayscale bitmap images as well. It has to be a true black and white image the laser is pulsed on for black areas and off for white, and it runs like a printer back and forth across the image, and at the end of one line it will step up one line and repeat. When watching it, it looks like a giant inkjet printer. The machine uses a .mol file which I think is a machine operating language file. Probably similar to G-code.
