Designed a three axis CNC cup-drawing robot. Iterated through three generations of prototype and assembled a small run of production units, which are permanently installed in an exhibit space. A handful of custom food-safe parts are exposed above a solid Ash routed base. A bunch of linear bearings, lead screws, stepper motors, and a custom PCB are packed inside the 1.5” thick base to move each axis. The marker is spring-loaded for compliance on rougher surfaces, and can be swapped out via a threaded cap on the back of the stainless-steel holder.
