Low-Cost CNC Router

It's been quite tough trying to make up my mind on what to do for my final project, but I've finally decided to make a low cost CNC machine. My reasons for chosing this as my final project is very simple:

  • A CNC router is always a very useful addition to any fablab
  • Fablab 2.0 is all about Machine Building - using the existing machines in a fablab to make new machines.
  • I'm very interested in building low cost machines, fabricating the mechanical & electronics circuits in-house using materials available in our fablab. Apart from the stepper & spindle motors and power supply, most of the parts should be able to be made within our fablab.
  • By changing the delivery mechanism and payload, a CNC router can easily be converted into other useful machines for a fablab, such as 3D or PCB milling machine, a laser cutter or 3D printer.

    Some of my project goals for the CNC router:

  • Based on Arduino (ATMega328) - easily fabricated in-house
  • Use free or open-source software as much as possible
  • Design can be adapted for different work areas, from small PCB mill to mid-sized router.
  • Sufficient accuracy/resolution to mill PCBs for our Fab Academy course.
