Time to add Arduino and some other electronic components to the DIY Dremel CNC machine! We will also upload code to the Arduino (GRBL) and take a look at software to control your machine (GRBL controller and CNCjs). At the end, we will run the first tests on the machine to see how it works :)

I am extremely happy with how this machine works! It's super quiet and works extremely smoothly. Construction is very rigid and 3D-printed parts are okay. The first drawings are also great all lines are sharp and the dimensions are good.

I always wanted to have one of those fancy CNC machines that can mill metals. It's cool and it gives you so many possibilities for your next projects! I already have a few ideas for projects with a CNC machine :)
