Genmitsu 4040-PRO MAX CNC Router: Big Projects, Bigger Precision!
Take your creations further—engineered for stability, accuracy, and power, the Genmitsu 4040-PRO MAX CNC Router is designed to handle larger projects while delivering professional-grade performance on your workbench.
The Genmitsu 4040-PRO MAX offers an impressive 400 × 400 mm work area, giving you the space to tackle more ambitious designs without losing precision. From hardwoods and plastics to acrylics and even soft metals, it cuts, carves, and engraves with confidence. Its heavy-duty all-metal frame and enhanced linear motion system minimize vibration, while the 710 W spindle ensures consistent, powerful results across a wide range of materials.
With GRBL compatibility, advanced safety features, and upgrade support for a 4th axis or Y-axis extension, the 4040-PRO MAX is built for makers, hobbyists, and professionals who want a larger CNC that grows with their projects.
Key Features of the Genmitsu 4040-PRO MAX:
-
Rigid All-Metal Frame + Linear Guide Rails: Enhanced stability and reduced vibration even under heavier cutting loads.
-
Large 400 × 400 × 78 mm Work Area: Big enough to tackle larger projects while still fitting on many workbenches.
-
Upgraded X & Z Motion Structure: X-axis uses modified SBR16 linear rails + leadscrew; Z-axis uses linear rails + leadscrew design for more robust vertical control.
-
High-Power 710 W Compact Router Spindle: Easily handles cutting and engraving tasks across a wide material range.
-
Generous Pass (Clearance) Height – 100 mm: Sweeps beyond typical desktop routers to allow thicker workpieces.
-
Wireless-Capable Mainboard + Accessory Ecosystem: Supports optional WiFi module, 4th axis rotary, Y-axis extension kit, dust shoe and more.
-
User-Friendly Design: GRBL firmware support (Candle, UGS, LightBurn), limit switches, emergency stop, and comprehensive resource support from SainSmart.
The Genmitsu 4040-PRO MAX is more than a CNC—it’s a powerful desktop workshop that blends size, strength, and precision into one reliable package.
Cut Through More Than Just Wood
Thanks to its 710 W compact router spindle, the 4040-PRO MAX can engrave and cut through wood, plastics, acrylics, carbon fiber, PCB, and even aluminum stock (with shallow passes). It opens up new creative possibilities for makers and small workshops looking to expand beyond simple materials.
Precision That Scales With Your Projects
With typical repeatability down to ±0.1 mm, the 4040-PRO MAX ensures clean, professional-grade results even on large projects. Dual linear guides and precision ball screws across all axes keep motion stable, minimizing errors and burrs—even when operating at higher speeds.
Quick Assembly, Lasting Reliability
Pre-assembled modules make setup simple. Most users can get the 4040-PRO MAX ready to run in under 30 minutes, a fraction of the time compared to similar-sized machines. Dust-proof covers and high-quality components reduce wear and extend machine life, giving you more time to create and less time to maintain.
Take Control the Easy Way
The CNC runs on a 32-bit GRBL mainboard, making it compatible with popular software like Candle, UGS, and LightBurn. Limit switches and an emergency stop button ensure safe operation, while optional accessories like an offline controller or WiFi module give you greater flexibility to manage projects your way.
Expand Into 3D and Beyond
Want to carve cylindrical workpieces or larger panels? The Genmitsu 4040-PRO MAX supports a 4th axis rotary module, dust shoe, and Y-axis extension kit. Whether engraving custom rings or producing oversized signage, this CNC is designed to evolve with your ambitions.
The Genmitsu 4040-PRO MAX CNC Router is the ultimate blend of size, power, and precision. From hobby projects to small-business production, it’s engineered to grow with your creativity and deliver consistent results you can trust.
