This system can cut 2d and 3d shapes from materials such as wood, plastic, metal and composites. Useful for cutting things that can't be cut in the laser cutter. We made this CNC from the UCL donated linear slides and stages, and other things lying around the space, and some bits and pieces that members had. Any suggestions for improvements / modification are welcome.


  • Spindle 1000 to 20000rpm
  • Rapid traverse rate at 100% 2000mm/min
  • Axis travel
    • X(longitudinal) 850mm
    • Y(cross) 960mm
    • Z(vertical) 80mm (Phase 1), 280mm (Phase 2)


The system currently runs GRBL 0.9 and is very similar to use to the Shapeoko2.

Using the system

  • The spindle is currently fitted with an ER20 collet chuck and can take cutters up to 13mm diameter. Collets can be found on top of the Boxford CNC.
  • To start the spindle, press the green button on the VFD. Use the up and down keys to vary the speed.
