Universal Electronics Box
The Universal Electronics Box (UEB) is a modular DIN-rail electronics enclosure for Millennium CNC builds. It packages mains distribution, DC power, contactor control, and board mounts in a printable, extrusion-based frame with panel covers and integrated cable channels.
This site hosts the bill of materials, printing settings and part list, and a link to the wiring reference PDF. STLs, DXFs, and CAD live in the Universal-Electronics-Box repository. Step-by-step wiring diagrams are in the PDF—not duplicated here.
Warning
This enclosure carries mains voltage. Follow the wiring PDF, use an appropriate E-stop, and comply with your local electrical codes. If anything is unclear, ask on the Millennium Machines Discord before energizing the cabinet.
What to expect
The wiring reference is titled V2 / V1.6 wiring reference and is intended alongside Milo V2 / Miley V2. Mechanical assembly, RRF install, and pre-flight checks for the mill remain in MiloV2-Manual.pdf. Use UEB docs for enclosure parts, printing, sourcing, and cabinet wiring.
