This video shows modifications to the Shapeoko XXL CNC frame and bed to accommodate a manual rotary setup that allows for multi-sided 3D carving of objects (along a B-axis) that are too big to fit underneath the X-gantry rail.
To show proof of concept, I carved a Koi fish from a solid stack of plywood with 3-sided CNC routing.
- Meshmixer to create the 3D Koi fish
- Vectric VCarve to generate the tool paths
- UGS Platform to send the Gcode to the CNC
- Everbilt 1 inch square tubes with 5/16" holes spaced 1" apart
- 1/4" steel triangular plates
- 3/8" bolts (the 5/16" holes were widened with the drill press)
- 18 mm (3/4") Sande plywood: 4 sheets of 600x600 mm (4’x4’)
- Surfacing bit to flatten and pocket the stock: WhiteSide #1027A
- Extra long roughing bit: Amana Tool end mill #46590
- Extra long finishing bit: Amana Tool ball nose #46490
