Source: sienci.com (verified 2026-08-09). Sienci's own MK2 48x30 announcement post confirms the 1219x762mm (48x30in) work area, lead-screw-driven extruded aluminum construction, and the recommended Makita RT0700/RT0701 trim router (1-1/4HP / ~710W, 10,000-30,000 RPM, run in a 15,000-25,000 RPM sweet spot per Sienci's own guidance). Sienci publishes Z-axis clearance rather than a standalone Z-travel figure, and does not publish a maximum feed rate or repeatability tolerance for the MK2 (lead-screw, not ball-screw, motion), so those fields are left null rather than guessed.
