Another image of Brittany Snow produced in a slightly different way.
The initial image was resized to 100mm x 135mm, adjusted in brightness and contrast then processed with PicEngraver’s excellent program PicDither using the Sierra algorithm. It was then reduced to 2 bit with IrfanView, saved as a .bmp file and the GCode created with the new Hungarian program DotG, in dot mode, at 0.25mm step over.
The result comprises 77,800 laser produced dots and took approx 50 minutes to complete, using the recently fixed M10 / M11 command set. The material is a faux-aluminium faced plastic engraving laminate (a non-pvc, laser friendly material).
Tweakie.
