What do you plan to do with this? create g-code to machine dot patterns?
I kind of like the idea of dots as opposed to v-carve type situations where it's a line streaking through the image, probably make a better output. Granted the disavantage being that it would take a long time to machine I would think.
What is an EPS file? if you could output that, could you then machine that? I could think with a few parameters it would be easiest to just output the g-code.
