The first, big project I did was building a 3d-printer. It started about two summers ago. I bought a RepRap printer off the internet. It came on time and looked wonderful, but it wouldn't turn on. (Upon retrospection, my power supply may not have been able to handle the high amperage required to run the thing, but give me a break -- I was still an electronic noob at that point). So naturally, as any young kid would do, I decided to build my own. Their's looked miserable in my ridiculous opinion. Not nearly enough intricacy. It looked something like the printer below.(I wasn't documenting at that point.)
So I started on my adventure. It started off well, I had all the required parts from the scrap 3d-printer. I had 4 Nema-17 motors and some threaded rod. I designed my printer, and started creating.
