How saatom/wedge_cutter works
This repository describes a physical dispenser for 0.160-inch TREMCO POLYSHIM II window wedges, with mechanical CAD, embedded firmware, and an instruction manual. The documented product goal is dispensing wedge material; the README also specifies a NEMA 23 stepper, power rails, and Raspberry Pi Pico firmware uploaded manually. The manual and firmware source were not sampled, so the graph avoids assuming operating steps or firmware-to-actuator calls. CAD files are represented as design artifacts rather than an inferred assembly sequence.
