This is the project page of a CNC capable of milling 4' x 8' plywood sheets. Update: I have ordered a 52" x 104" (area) Plasma cutting table from eagleplasma. Updates to follow below:


  • 10or11 May 12: Ordered CNC Kit from eagleplasma.com
  • 16 May 12: Kit arrived in 3 boxes (145#, 145#, 95#) - I like to call them Huey, Duey, and Louie
  • 17 May 12: Uncrated the contents. (see below for pictures)
  • 18 May 12: ASSEMBLY
  • 28 May 12: Built Spindle Mount
  • 30 May 12: Calibration

Design Notes

  • Able to fully access an entire 4' x 8' plywood sheet
  • Able to be moved
  • Belt driven (screw drives are buggy, albeit more accurate)

Of concern: The ground is not connected
Of concern: The power wires seem a bit thin...
Fixed ground. Other wires seem ok.
