I haven't updated in awhile. I got a new job this summer working for a startup, and moved cross country to Florida. That soaked up most of my time, but I have made some progress on the project.

Given my limited time, I made a big mistake with how I went forward with the 3D printing. I spent several weekends trying to resurrect my old Kossel (RepRap delta printer), and achieved only dismal results.  There were a lot of little problems that were frustrating to overcome. In this case, my instincts of trying to implement everything myself really failed me. If you have infinite time, it is a great ethos, but if you have a deadline, it's terrible.

With the deadline looming, I ordered a Lulzbot Mini 2, and it arrived just in time to give me one last weekend to produce a new prototype before the last round of Hackaday Prize qualifications. Thankfully, the Lulzbot was plug and play, so I was able to focus on the project and not the 3D printer.
