I’ve wanted to build a top shelf 3D printer kit for a while, and now I present part 3 of the Rat Rig V-core 3 series. This appears to be an outstanding design: rigid, high quality, modular and containing amazing features such as a three point kinematic tool plate bed. My patrons helped me choose this and so far I’m very happy with it.

In the third episode, we cover questions and comments from part 2, wiring, what Klipper is and why I chose it, Klipper setup and checks. We also demonstrate the kinematic bed and produce our first print.

Next episode will feature detailed calibration, such as using an ADXL accelerometer to find resonant frequencies and eliminate vibrations during high speed printing.

This kit was purchased with my own money, apart from the shipping which was provided free of charge by Rat Rig. All opinions expressed are my own. Please pay attention to the safety warnings if you are attempting your own mains wiring. Consult a professional to ensure your safety.
