Lazer Cutter- Raster Engraving

I’m looking into doing engravings from Raster (bitmap) images. Whilst it’s easy enough to down-convert images from 8 bit greyscale to 1 or 2 bit greyscale (2 or 4 shades), some research might be needed regarding how best to convert this into an engraving. Whilst I understand that this is within the machine’s specification, I might request from input from Tom regarding how to do such a project safely.

Right now the laser cutter does not do engraving because it has a fault, hopefully this will be fixed early September.

You don’t need to do conversion the machine does this for you. While you can posterise the image to get the appearance of levels of depth it will also do half tone and other dithering patterns to make a grey scale effect like an ink jet printer.
