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
  • 13 Jun 12: First cut: X-Axis had trouble with belt jamming; upped the Amperage to 100%-->20%; Need to play around with one of the pulleys to see if i can keep it from pinching the belt. Opinion: This would not be a problem if I were plasma cutting. The router is adding resistance that the stepper is having trouble adapting to. Worst case scenario: I replace the current NEMA23 stepper with a spare NEMA34 that was used in the old cnc..

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