Ultimaker - The Ultimaker 2
Taking a brake form the tachometer to start playing around with OLED and creating a menu system. I’m far from done (nothing really works) but its a start. I think all you need to have installed is Adafruit SSD1306 library, python and perl. Unzip mlmcnc09.zip in your Pi's documents folder and run main.py.
