Thats the problem. I got my Robo 1 and Robo 2 at about the same time. Then I built my Prusa and have been using that more than the other two printers. Since I built it, I know a lot more about how it works. Now I'm trying to get back to using my Robos, with my R1 being my "Spare Parts" printer. It's weirdly frustrating because everything is hidden behind plastic.
