Different than your examples. But I just finished making my own "Mostly Printed 3D Printer". I'm a software dev but had basically no experience with Arduino or anything else related to the project. It made me feel like when I was a kid on Christmas with a new large Lego set. One of the most educational and fulfilling projects I've done in recent memory. It was good timing too because the motherboard on my 3d printer just shorted out. I didn't want to pay the full price ($115) for a replacement board. So I bought an open source board similar to the one I used for my MPCNC. Since I had just put that togheter I knew what I was doing even though there was limited help in converting my particular printer available online.
