I designed and built a 3-axis CNC cutter. I developed a custom G-code interpreter and a stepper-driven Cartesian motion system. I enjoyed furthering understanding of the underlying mechanics and programming for larger CNC machines.

This was a prototype project using lead screws and stepper motors for precise vertical motion, meant as a precursor to my 2D plotter, and eventually my 3D Cutter. I wanted to explore and gain a better understanding of how to design for assembly, and how the assemblies I build in CAD are reflected in reality.

I design this variable-distance cart with two friends. We used bang-bang control to transport an unstable vertical bar quickly without tipping. We entered this cart to compete in a speed and stability contest. Working on it allowed me to deeply understand DC motor control, and the complex trade-offs between balance and speed.

I wanted to explore how I can incorporate aesthetic form as a complement to a design's function, through the process of making myself a phone stand. I explored some alternative designs with different manufacturing methods, but was delighted with how this minimalist aluminum stand turned out in my decor.

Before beginning my 3D Cutter project, I wanted to more deeply understand stepper motors, lead screws, and automated motion via G-code. In the process, I found myself deeply intrigued by cartesian motion systems and worked through the challenges of driving my plotter design via both a joystick based manual control, and an alternative, precision-centered G-code program.

This is one of many examples of mechanical forces and processes that intrigue me. This specifically is a quick study of four-bar assemblies in SolidWorks. It allows me to explore motor torque and motion pathways. From explorations like this, I've developed a deep understanding of how degrees of freedom and proper constraints result in improved accuracy in my design projects and those of the clients I help at BU.
