Custom-designed CNC Milling Machine

2018 / Matías Bergerman, Joel Gottfried

Summary 🔗

This project consists of a CNC milling machine constructed mainly with laser-cut wooden pieces and 3D-printed plastic parts. The goal was to manufacture a low-cost CNC Mill in order to easily fabricate parts needed for other projects. The main features of this build are:

• The movement is achieved with the use of stepper motors and lead screws. The axes are mounted on smooth steel rods using linear bearings.
• For cutting, we use a 500W mill with an ER11 chuck and an independent power supply.
• The electronic controller is a RAMPS 1.4 board mounted on an Arduino Mega.
• The control firmware is Marlin, with custom modifications in order to fit the use case.
• The 3D modelling was made using OnShape.
