The The Genmitsu 4040-PRO MAX represents the next evolution in desktop CNC machining. Responding directly to user feedback, we have reinforced the chassis, upgraded the motion system, and integrated a powerful 710W router with digital display to handle both intricate wood carving and demanding metal milling tasks with ease.
REINFORCED PLATFORM STABILITY
Addressing common flatness issues, the upgraded spoilboard features a central aluminum support bar integrated with T-tracks. This hybrid design reinforces the MDF to prevent sagging under load, ensuring a level surface for precision metal milling and detailed wood carving.


Increased Z-axis Pass Height
With a 400x400x78mm (15.7" x 15.7" x 3.1") active area and a massive 100mm Z-pass height (40% higher than the PRO), this machine easily accommodates thicker stock, tall relief carvings, and add-ons like rotary axes without sacrificing vertical clearance.
High-Performance 710W Spindle
This CNC router features a powerful 710W spindle, meticulously selected for its ability to cut through tough materials like aluminum effortlessly. With a perfect 5-star rating on Amazon, this spindle is highly recognized by customers for its precision and reliability—it's not just any spindle, it's a choice made with care and customer satisfaction in mind.


Versatile Compatibility
Compatible with almost 4040-PRO accessories, including routers, four-axis modules, WiFi modules, relays, clamps, and extension parts, the 4040-PRO MAX offers versatile options for customization and expansion. (Only compaitble with the Y-axis extenstion kit.)
User-Friendly Design
Featuring a comprehensive control system with GRBL firmware-compatible software (such as Candle, LaserGRBL, and LightBurn), an intuitive offline controller (sold separately), and safety features like an emergency stop switch and homing button, this CNC router is designed for both novice and experienced users.
