Zach Smith from RepRap here. Saw your work on Hackaday and popped in to say hi. Looks like you’re doing some good stuff, and I wanted to wish you luck.

Also, I notice you’re using Arduino to control your machine. We also made the switch to Arduino over here at RepRap. Since we’re using a shared environment, it would be great if we could collaborate. We have some cool stuff you might be interested in: software, firmware, and electronics.

Hit me up via email at hoeken at gmail dot com. Lets chat!
