The Shapeoko 3 XXL is one of the most popular desktop CNC machines on the market, known for its large work area, high precision, and overall versatility. As a hobbyist or professional maker looking to add computer numerical control (CNC) capabilities to your workshop, the Shapeoko 3 XXL deserves strong consideration.
In this in-depth review, we’ll cover everything you need to know about the Shapeoko 3 XXL, including its features, specifications, performance, pros and cons, and how it compares to other desktop CNC options. By the end, you’ll have all the information you need to determine if the Shapeoko 3 XXL is the right CNC machine for your needs and budget.
Overview of the Shapeoko 3 XXL
The Shapeoko 3 XXL is manufactured by Carbide 3D, a leading maker of hobbyist and prosumer CNC machines. It represents the extra-large version of their popular Shapeoko 3 line, with a work area of 33″ x 33″, making it one of the largest desktop CNC machines available.
Like the other Shapeoko 3 models, the XXL uses an open frame design. This means the x, y, and z-axis rails and components are all openly exposed instead of being enclosed in a case. The machine comes partially assembled, requiring some simple construction to get up and running.
The Shapeoko 3 XXL can perform all standard CNC operations – milling, drilling, carving, engraving, and more – in materials like wood, plastic, aluminum, and even some metals when equipped with the proper bits. It’s capable of handling subtractive manufacturing tasks with precision and repeatability.

- Cutting Depth: Up to 0.5” in hardwoods, deeper in softer materials.
- Precision: Achieves accuracy down to 0.001” (0.025 mm) or better for quality parts.
- Speed: Cutting speeds up to 400+ ipm reduces machining time.
- Processing Power: Can handle complex 3D toolpaths and geometry.
- Safety: Includes an emergency stop button for quickly halting operation.
The XXL model can tackle everything from small detailed parts to large projects like furniture components, signs, cabinetry, decorative panels, scale models, enclosures, prototypes, and much more. Its capabilities make it a versatile choice for woodworking, fabrication, prototyping, hobbying, and small business manufacturing.
While not an industrial machine, the Shapeoko 3 XXL delivers excellent precision and repeatability for the price. The quality of construction and components results in smooth, accurate cutting and milling. Runout is minimized for clean edges and details in parts.
Software and Compatibility
The Shapeoko 3 XXL runs on Carbide Motion, a lightweight CNC control software developed by Carbide 3D. It streams gcode instructions to the machine and provides an intuitive interface for jogging, homing, and zeroing out your workpiece.
Carbide Motion works seamlessly with common CAD/CAM programs used to generate toolpaths and gcode. This includes:
- Fusion 360: Includes a custom Shapeoko post-processor for Fusion 360 CAM.
- Vectric VCarve Pro: Popular for 2D design and toolpath generation.
- MeshCAM: Affordable CAM for processing 3D mesh and relief models.
- Other programs: Compatible with Aspire, SolidWorks CAM, FreeMill, pyCAM, and more.
The machine itself can accept standard gcode files generated by any CAM solution. For 3D designs and complex parts, Fusion 360’s powerful CAD and CAM tools are recommended to fully unlock the CNC capabilities.
Carbide 3D also provides detailed documentation for getting started machining with the Shapeoko 3 XXL, including tutorials, setup/use guides, tips and tricks, and extensive troubleshooting resources.
Assembly and Setup
The Shapeoko 3 XXL arrives partially disassembled in kit form. Assembly of the frame, gantry, and motion components takes 2-3 hours following the well-documented instructions. All required tools are included aside from a Phillips screwdriver.
The instructions walk you through these primary assembly steps:
- Assembling the frame and gantry from aluminum extrusion rails and corner brackets
- Installing the Z-axis lead screws and stepper motor
- Attaching the X and Y-axis motors and drive belts
- Mounting the electronics enclosure and wiring up all components
- Adding machine feet, cable chains, and other accessories
No soldering or complex electrical work is required. The wiring is simple and connectors are clearly labeled. Setup is straightforward enough for most hobbyists and makers. All hardware and fasteners are included.
Once assembled, you’ll need to tram and tune the machine using the provided setup tools and digital dial indicator. The setup procedure ensures the gantry is properly squared and the router bit moves evenly across the entire work area.
This crucial step accounts for any minor variation in the assembly and allows you to dial in precision. The detailed instructions make tramming and tuning straightforward with a little patience. Expect it to take 1-2 hours the first time.
Add-ons and Accessories
Carbide 3D offers a few add-ons and accessories to expand the capabilities of the Shapeoko 3 XXL:
- HDZ Z-Axis: A heavier duty z-axis upgrade that increases cutting depth to 2”. Great for cutting harder materials.
- BitSetter: An automatic tool length sensor for quickly zeroing your router bits. Speeds up workflow.
- Dewalt DW660: The recommended router with adjustable speed from 8k to 24k RPM. Sold separately.
- Wireless Job Start: Start jobs remotely from your computer over WiFi.
- Dust shoe: Attachable shoe to help control dust and debris. Requires shop vacuum system.
- Work Stop: Allows precisely repeating cuts of the same depth. Helpful for batch projects.
- ** Drag Knife:** Attachment for swapping in a drag knife for vinyl cutting, papercrafts, etc.
For keeping dust under control, a shop vacuum with fine dust filter is highly recommended. Clamping solutions, end mills, and other basic accessories will also come in handy.

Shapeoko XXL vs Standard vs Pro Models
Carbide 3D offers three Shapeoko 3 models to fit different needs and budgets:
- Shapeoko 3 XXL: 33″ x 33″ work area. Starts at $1,725.
- Shapeoko 3: 24″ x 24″ work area. Starts at $1,250.
- Shapeoko Pro: 30″ x 30″ work area. Starts at $2,800.
The XXL sits between the Standard and Pro models in terms of size, capabilities, and price. The expanded work area allows you to manufacture larger parts compared to the Standard 24” x 24” model.
The Pro model is geared more towards production shops and professional environments. It includes fully enclosed rails, a brushless spindle, HDZ z-axis, and integrated accessories. But it also jumps up significantly in price.
For many makers and hobbyists, the XXL hits the sweet spot – delivering larger capacity than the Standard model while still being reasonably affordable for home and garage shops. Unless you need the features of the Pro model, the XXL is likely the best balance for most personal or small business applications.
Where to Buy the Shapeoko 3 XXL
The Shapeoko 3 XXL is sold primarily through the official Carbide 3D website. It’s priced at $1,750 for the machine kit and $250 for the DeWalt DW660 router for a total starting price around $2,000.
Carbide 3D also offers convenient financing options to split your purchase into multiple interest-free monthly payments.
The Shapeoko XXL kit includes everything except the router. Make sure to budget several hundred additional dollars for end mills, materials, and accessories like clamps, a vacuum, and safety gear. A basic starter bit set will help you get up and running.
Final Recommendation
The Shapeoko 3 XXL lives up to its reputation as one of the best desktop CNC machines for hobbyists, makers, and small workshops. With its enlarged 33” x 33” workspace, industrial-grade components, precision and speed, it’s incredibly versatile for the price.
If you need the capacity to machine larger parts up 24” x 24”, crave the high accuracy and repeatability of CNC, or want to expand your making capabilities, the Shapeoko 3 XXL is a worthy investment. Both beginners and experienced makers can benefit from its approachable setup process, powerful included software, and helpful community resources.
For under $2,500, it’s hard to find a desktop CNC that can match the XXL model in terms of quality, precision, cutting area, reliability, and long term value. Just be sure to budget for accessories and tools to maximize the machine.
