How to compile and run Klipper on atmega2560 + OctoPrint from Windows 7 x64

Situation

• I own an Anycubic Kossel delta 3D printer, running custom Marlin firmware, custom mainboard(atmega2560), connected to my PC via USB (USB Serial), controlled mostly via Printrun(Pronterface)
• I want ultra high performance and latest improvements in my 3D printer, with the help from Klipper software/firmware
• Normally you should go get an Raspberry Pi and do everything (compile/install Klipper / OctoPrint) from there, but I don't have a Pi, don't want to mess with the cables, decided to run Klipper from my PC

INTRO

Concurrency is a domain I have wanted to explore for a long time because the locks and the race conditions have always intimidated me. I recall somebody suggesting concurrency patterns in golang because they said "you share the data and not the variables".

Amused by that, I searched for "concurrency in golang" and bumped into this awesome slide by Rob Pike: https://talks.golang.org/2012/waza.slide#1 which does a great job of explaining channels, concurrency patterns and a mini-architecture of load-balancer (also explains the above one-liner).

Let's dig in:

TL;DR

• Create 10GB FreeBSD image using QEMU.
• Run the VM using xhyve.
• Mount host directory.
• Resize the image.

Requisites

• OSX
• Homebrew

Raspberry Pi Zero OTG Mode

Simple guide for setting up OTG modes on the Raspberry Pi Zero - By Andrew Mulholland (gbaman).

The Raspberry Pi Zero (and model A and A+) support USB On The Go, given the processor is connected directly to the USB port, unlike on the B, B+ or Pi 2 B, which goes via a USB hub.
Because of this, if setup to, the Pi can act as a USB slave instead, providing virtual serial (a terminal), virtual ethernet, virtual mass storage device (pendrive) or even other virtual devices like HID, MIDI, or act as a virtual webcam!
It is important to note that, although the model A and A+ can support being a USB slave, they are missing the ID pin (is tied to ground internally) so are unable to dynamically switch between USB master/slave mode. As such, they default to USB master mode. There is no easy way to change this right now.
It is also important to note, that a USB to UART serial adapter is not needed for any of these guides, as may be documented elsewhere across the int
