Yes, the stepper is only on when it's moving. This particular stepper can handle up to 1.2A per coil, but I'm not using it to capacity. Laser cut would work, and the plastics place I buy the acrylic offers laser cutting.
Nice job with the whole project. I really love the YouTube video. I'm sorry that I'm a little late with my comment, but haven't been posting for a while. I have to post the coolest projects.
