Thanks sounds good. No havent made any new ones. I've moved twice in this last year so it's been busy. I'll let you know though as soon is I get everything up and running again.
Hey I have a question. I was thinking of buying your pixel cnc, do you plan on integrating any rotational axis like a, b, or c. I ask because I'm building a 5 axis cnc and I like the look of your program.
* I use a fairly massive CNC machine to drag a diamond stylus through aluminum alloy at a depths of 20-50 micron. Had to customize some machine parts and programming to get optically smooth motion. * It helps to tilt the stylus slightly in the direction of motion and to use a very light-gauge lubricant. I grind & polish the stylus to a Rouleax-like shape to promote reflectivity. * Everybody gets the geometry of the stylus motion curves wrong — they're not conic. You need to solve an ODE that asks for rigid 3D image motion when some part of the optical path (e.g. the plate) moves. * Lighting should be consistent with whatever assumptions you make in your ODE. Point-like sources work best; broad-spectrum sources allow diffractive color effects."
