Now, we make the chessboard, and for that I used the Lasercut.
The first one I do, I used wood but I put to much power and the machine engraved too much the wood.
So I make another but this time with quite no power (Power 15% and Speed 80%), and it works better !
And finally, I decided to make it with plexiglas with a speed at 60% and a power at 15%.
The first step of my project is to print the pieces with the 3D printing.
For that, you can draw them yourself or take them from a STL file. Here I took them from Thingiverse (http://www.thingiverse.com/thing:470700), because it would take a lot of time to me to draw them myself.
Print all the pieces is very long !
So to organize well your time I advice you to print them during the night.
