In this video I convert my 3-axis Proxxon MF 70 micro milling machine into a CNC version with digital readout. The heart of the system is an Arduino Uno.
In manual mode the digital readout and adjustable travel speed makes milling with this machine much easier and comfortable. No more counting errors!
The milling program at the end of the video is programmed in the Arduino Uno. This milling sequence for making the multicopter arm takes 36 minutes to complete. It only takes 40 lines of code to do the job. So no cad-cam computer is needed for this simple milling sequence.
