Conference builds a live collaboration system that takes touch or JavaFX/Gluon mobile drawings, issues an ID stored in an Oracle Cloud REST backend, and prints parts on affordable Carbide 3D CNC routers driven by Raspberry Pi + Java nodes. Workflow converts Java2D/SVG paths to G‑code (uses Universal Gcode Sender), fixes curve/offset issues with JTS geometry for stroke outline, and scans QR badges with a Pi camera. Setup runs reliably across multiple machines but needs occasional restarts and threading/serial-port fixes.
