“A Pizza-Preparing, Tool-Changing, 3-Axis, 3D-printed CNC Machine!
Hey! I’m Teddy Warner,a senior in high school enrolled at Charlotte Latin School in Charlotte, North Carolina. I have a great interest in modern digital fabrication technologies such as 3D printing & CNC machines.
The Pizza-Pizza CNC Machine is a Marlin-based three-axis CNC I developed alongside three of my friends. My contributions to the project include the gantry, electronic housing, and parts of the frame CAD, as well as the machine’s electronics system, firmware, and pizza-preparing gcode. This publication covers the fabrication of the CNC in-depth, with a focus on my project contributions, while also including final-result media.
The machine includes two tool ends, one for sauce distribution and another for cheese, with the potential for expandability to have toping tool ends in future iterations. The CNC is mostly 3D printed, with the exception of its aluminum rails and laser-cut wooden baseplate, and operates with a mini RAMBo - or RepRap Arduino-Mega-compatible Mother Board.
