CNC Cheat Sheet

So my EMCO mill suddenly started working after months of stress and although I have become fairly familiar with operating it I quickly realized  that I know diddly squat about the important CNC milling stuff like G-Code or  how to work a CAD/CAM software to actually be efficient at milling. So I googled "G-Code cheat sheet", and to my amazement not a single high-resolution, colorful, to-the-point, well explained PDF file popped out. I was flabbergasted.

But, there were, after some digging plenty of black-text-on-gray-backround websites with comprehensive lists of G-Code that would be very useful. If only they were in printable format, to hang on the wall behind my machine...

So I decided to make one!
