2. Cutting and milling the board.

First of all, we have to consider that our milling machine works with Linux. It was the first time that I worked with this operating system but I founded really similar to windows so I didn’t had any problem with that. Secondly, we have to know that our machine doesn’t work with a pre-installed program in our computer but it does through the internet: fablabmodules, program that allows us to handle the machine from our internet browser.

We will be milling the board using a precision desktop milling machine the Roland SRM-20.
