I'm at a slight stand still till I can get my Stepper Motors, maybe at next payday. Meanwhile I was trying to figure out how the Arduino will run the laser. It seems to be setup for 3 axis's. Will I need an extra stepper and diver for an encoder or does it use dithering, is it something else? I have the PicSender in the Computer and I have been trying to get the settings right. That is all working but I probably won't know anything for sure until I get it setup on the laser.
