If I was smart enough! Well, not quite true, I would just need to buy the bead plunger/thingy. The machine will make lovely round holes for the raster beads. Don't have the need for it, so haven't pursued it.
I was watching my engraving genius guy figuring out how to do it himself, with his Q1 24"x 24". I believe it's one of the first machines Fred made! He had the bead thingy hooked up separate from the spindle, offset worked out so that the holes would engrave first then, the plastic beads would be placed. This was into lamicoid. He's still r&d'ing it
I've had good experience with my Xenetechs. I have two "mature" machines, still working well.. Just don't try to do stainless
Good luck!
