Overview

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:


Status

  • 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..

Crate Contents

The crates arrived! the vertical one weighed 95lbs, and the two horizontal ones were 140lbs!
The Gantry box without its cardboard. see the dalek in the background?

Concerns

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

Assembly Day

The table parts out of their plastic

More to follow once I've resized them.

Bill of Materials

This may be put on hold...
