@Riley_Porter_ril3y , one of the guys at Synthetos who make TinyG, just posted a pretty cool Instructable on how he built his laser projector. He uses ChiliPeppr to send the Gcode to it.

It just got accepted into the formlabs challenge too! If you like it vote it up!

That’s awesome man. You guys should really set something up so folks can contribute to the project.
