Lunyee 3018 Pro Ultra Desktop CNC Router Review: High-Precision Wood Carving & PCB Milling for Hobbyists

Written by Hank Sterling

I’ve spent the past couple of weeks testing the Lunyee 3018 Pro Ultra Desktop CNC Router, a high-precision CNC machine designed for hobbyists, makers, and DIY electronics enthusiasts. Unlike standard 3018 kits, this upgraded router fixes common issues such as wobbly rods, lightweight frames, and inconsistent carving or milling results. Featuring a robust aluminum frame, precision linear rails, and superior real-world performance, the 3018 Pro Ultra stands out among desktop CNC machines for small-scale woodworking, PCB prototyping, and hobby projects. After extensive hands-on testing with wood carving and PCB milling, here’s a detailed review focusing on build quality, precision, and versatility.

 

 

First Impressions & Assembly

The 3018 Pro Ultra arrives neatly packaged, with most components pre-assembled and clearly labeled. The gantry and Z-axis are mounted as a single unit, making assembly beginner-friendly. Step-by-step instructions with photos simplify setup, ideal for DIY CNC beginners working on woodworking or PCB projects.

 

The GRBL controller board mounts securely on an acrylic plate, with organized slots for stepper motors and tidy cable routing. While offline microSD operation is supported, connecting the router to a PC using Universal Gcode Sender (UGS) or Fusion 360 provides smoother multi-pass operations and more precise results. Included accessories such as T-track mounts, starter end mills, silicone feet, and linear rail lubrication enable immediate operation without extra purchases.

 

 

Build Quality & Mechanical Design

The first notable improvement over standard 3018 kits is rigidity and frame stability. The thick aluminum frame, reinforced gantry plates, and precision linear rails reduce vibration, allowing confident handling of wood, plastics, soft metals, and PCBs. Minimal Y-axis flex under heavier cuts is acceptable for most hobby projects, including decorative engraving and prototyping.

The Z-axis features thicker rails and an ER11 collet spindle, which reduces runout and increases stability. Dual brass nut T8 lead screws minimize backlash, ensuring consistent results for multi-pass engraving and PCB milling. Cable management is practical, keeping wires organized and safe. Overall, the 3018 Pro Ultra feels like a serious hobby CNC machine rather than a typical entry-level router.

 

Spindle & Tool Holding Performance

The 500 W DC spindle reaches speeds up to 12,000 RPM. Switching from a set-screw holder to an ER11 collet reduces runout to about 0.05–0.1 mm, enabling precise wood carving and PCB milling.

The router integrates smoothly with Candle, UGS, and Fusion 360, with reliable homing, manual zeroing, and soft limits. For complex or multi-pass projects, a PC connection is recommended, ensuring consistent results across different materials and designs.

 

 

Real-World Performance Tests

Wood Carving & Engraving

Using the 3018 Pro Ultra desktop CNC router, I created a detailed relief carving of a sailing ship on a wooden plaque. The machine handled fine lines, layered textures, and intricate borders with precision. Stepper motors tracked the complex design accurately, producing smooth surfaces and crisp edges even in small, delicate areas. This test confirms that the 3018 Pro Ultra excels at fine wood carving, decorative plaques, and small-scale woodworking projects, making it ideal for hobbyists seeking high-quality engravings on hardwood and MDF. These results highlight the 3018 Pro Ultra as a top choice for desktop CNC wood carving enthusiasts, capable of delivering precise and detailed hobbyist woodworking projects.

 

PCB Milling & Prototyping

For PCB testing, I milled an isolation pattern on a blank copper board using a 0.7 mm bit. The 3018 Pro Ultra produced clean, precise traces with minimal burrs and excellent alignment between pads and channels. The tight tolerances and clear paths demonstrate its capability for PCB prototyping, hobby electronics, and small component milling. Even with complex routing, the machine maintained stable spindle speed and accurate stepper movement, making it a reliable choice for electronics enthusiasts and DIY engineers. This test confirms that the 3018 Pro Ultra is a highly capable desktop CNC router for precise PCB milling and prototyping, ideal for hobbyists and DIY electronics projects.

 

 

 

Versatility Across Materials

Beyond wood and PCBs, the 3018 Pro Ultra performs well with:

• Acrylic & plastics – smooth engraving and cutting for DIY signage or parts.
• Soft metals – aluminum and brass can be milled with proper feed rates and shallow passes.
• Foam & composites – ideal for model-making or prototype fabrication.

Its versatility makes it an excellent choice for hobbyists, makers, and DIY engineers looking to explore multiple materials on a single desktop CNC machine.

 

 

Practical Tips for Hobby CNC Users

• Secure workpieces firmly on the T-track table.
• Calibrate X/Y/Z zeroing before each project.
• Use high-quality end mills and ER11 collets to reduce runout.
• Maintain a log of feed rates, spindle speeds, and cut depths for repeatable results.
• Use shallow passes to prolong spindle life and improve surface finish.

 

 

Pros & Cons

Pros:

• Sturdy aluminum frame and precision linear rails for enhanced stability
• ER11 collet reduces runout for precise wood carving and PCB milling
• Versatile across wood, plastics, soft metals, and PCBs
• Compatible with GRBL, UGS, Candle, and Fusion 360

Cons:

• Minor Y-axis flex under heavier cuts
• 300 × 180 mm workspace limits larger projects
• Offline controller is functional, but PC connection recommended for complex operations
