Sienci LongMill MK2 CNC Router

The Sienci Labs LongMill MK2 is a benchtop CNC router designed by makers, for makers. With a generous work area, robust aluminum extrusion frame, and open-source firmware, it offers the best value-per-square-inch in the desktop CNC market.

The LongMill MK2 cuts wood, plastics, and soft metals like aluminum and brass with a trim-router-based spindle. Its modular design means you can start with the standard kit and upgrade to extended rails, a laser module, or a 4th-axis rotary as your skills grow.

Key Specifications:

• Spindle: Compatible with standard trim routers (e.g., Makita RT0701C, sold separately)
• Working Area: 762 — 762 " —ï" —") — standard; extended kits available
• Frame: Custom aluminum extrusion with steel linear rails
• Motion: Lead-screw-driven on all axes
• Precision: 0.1 mm typical
• Materials: Wood, MDF, plastics, aluminum, brass, foam
• Software: gSender (Sienci—s free controller), Fusion 360, VCarve, Carbide Create
• Connectivity: USB
• Assembly: DIY kit assembly required (approx. 8—12 hours)
• Community: Active open-source community and extensive documentation

Applications:

Education: Technical colleges and high-school shop programs use LongMill MK2 for its real-world assembly experience. Students learn mechanical assembly, electronics wiring, and CNC operation while building a machine they can use for years.

Makers & Hobbyists: Woodworkers, sign makers, and furniture builders choose LongMill for the huge bed size at an accessible price. Cut full-size cabinet ds, and large signs that smaller mills cannot handle.

Small Business: Custom furniture shops, sign companies, and prop studios run LongMill for production cutting of plywood sheets, MDF molds, and foam architectural elements. The open firmware allows custom automation and integration.

Prototyping: Product designers and engineers prototype large-format parts, packaging inserts, and structural components in wood and plastic before committing to expensive tooling.
