Installing Klipper on Prusa i3 mk3

Installation of the π and printer

Introduction

The Prusa i3 mk3 series originally runs Prusa's own firmware, which is based on Marlin. Marlin works well, but it's a small and by today's standards, old microcontroller in the mk3 (and earlier) are Atmega controllers. In the mk3(s), it's an ATmega2560, the same chip used in the Arduino Mega 2560. Asking such a small thing to do all the heavy lifting, is unfair!
