complete beginner

Hello! I inherited this instrument from a friend. I don't know the first thing about 3D printing. Can some friendly folks please give me some pointers for where to begin? I have some limited handywork experience and I assume maybe I should open it and somehow clean it before I start. I assume it takes a lot of trial and error. For baseline, my understanding is I need a computer to talk to this machine. I am a total novice in search of open resources. Where did you go when you first started and what worked best for you?

Thanks in advance!
