3-sided rotary CNC routing with the Shapeoko - Carving a Koi fish

By Dennis Van Hoof, from Top o’ Arts (). 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. Software used: - Meshmixer to create the 3D Koi fish - Vectric VCarve to generate the tool paths - UGS Platform to send the Gcode to the CNC Materials used: - 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
