Lunyee 3020 Nova vs. 4040 Nova: Which CNC Router Is Right for You?

Choosing between the Lunyee 3020 Nova and Lunyee 4040 Nova is not simply a matter of choosing the larger CNC router. Both models share a 710W trimmer router, HG15 linear guides, and 1204 ball screws, and can handle a range of suitable materials, including wood, acrylic, aluminum, and brass, with the right tooling and machining parameters.

The key difference is working capacity. The 3020 Nova is designed for compact projects, home workshops, hobby use, prototyping, and smaller personalized products, while the 4040 Nova offers a larger working area for bigger workpieces, more demanding workflows, and small-scale production.

So instead of asking which CNC router is better, consider a more practical question:

Which machine better fits the projects you actually plan to make?

 

Lunyee 3020 Nova vs 4040 Nova: Key Differences

Specification	Lunyee 3020 Nova	Lunyee 4040 Nova
Working Area	300 × 200 × 80 mm	400 × 400 × 130 mm
Trimmer Router	710W	710W
Trimmer Speed	6,000–30,000 RPM	10,000–30,000 RPM
Linear Guides	HG15	HG15
Ball Screws	1204	1204
Stepper Motors	NEMA17	NEMA23
Motor Torque	0.89 Nm	1.21 Nm
Maximum Working Speed	5,000 mm/min	5,000 mm/min
Positioning Accuracy	≤ ±0.05 mm	≤ ±0.05 mm
Weight	19.2 KG	40.2 kg

The specifications show that these are not two completely different CNC systems. Both use the same 710W trimmer router, HG15 linear guides, and 1204 ball screws, with the same maximum working speed and stated positioning accuracy.

The 4040 Nova is built around a larger working platform, larger NEMA23 stepper motors, and a heavier machine structure. The 3020 Nova takes a more compact approach while retaining the core configuration needed for a broad range of CNC projects.

That difference matters because the best choice is often determined by the workflow rather than by a single specification.

Choose the 3020 Nova for Compact Projects and Home Workshops

The Lunyee 3020 Nova is a natural fit for users whose CNC projects are relatively small and who do not need a large machining envelope.

Typical applications include personalized signs, nameplates, decorative pieces, custom gifts, prototypes, PCB projects, and smaller aluminum or brass components. For these types of work, a 300 × 200 × 80 mm working area can provide enough room without requiring a larger machine.

It is also well suited to home workshops and makers who are still developing their CNC skills. Learning CAD and CAM, tool selection, workholding, feeds and speeds, and machining techniques does not require a large CNC when the projects themselves are compact.

The smaller machine also has a practical advantage when workshop space matters. At approximately 19.2 kg, the 3020 Nova is considerably easier to move and reposition than the approximately 40.2 kg 4040 Nova.

For a maker whose projects fit comfortably within the 3020 Nova's working area, choosing a larger machine may simply mean taking up more workspace without gaining much usable capacity.

Best fit: smaller projects, home workshops, hobby use, learning, prototyping, and compact products.

 

Choose the 4040 Nova When Project Size Starts Limiting the Workflow

The Lunyee 4040 Nova becomes the more practical choice when the size of the workpiece is starting to restrict what can be made.

Its 400 × 400 × 130 mm working area provides approximately 2.67 times the XY working area of the 3020 Nova. That additional space is useful for larger signs, panels, woodworking projects, relief carvings, fixtures, and larger custom components.

More importantly, a larger working area can reduce the need to divide a project into multiple setups.

When a design is too large for a smaller CNC, repositioning the workpiece can introduce additional setup and alignment work. A larger machine allows more projects to remain in one setup, giving greater freedom when planning the design and workholding.

The 4040 Nova also uses NEMA23 stepper motors with 1.21 Nm of torque and weighs approximately 40.2 kg, reflecting its larger mechanical platform.

The important point, however, is that the 4040 Nova should not be chosen simply because its numbers are larger.

It makes sense when the additional capacity will actually be used.

Best fit: larger workpieces, larger signs and panels, expanding projects, small-scale production, and users who need more room to grow.

 

For Beginners, Choose Based on the Projects Ahead

A beginner does not automatically need the smaller CNC.

The 3020 Nova is a sensible choice when the goal is to learn CNC through relatively small projects. It provides enough working area to develop the complete workflow from design and CAM preparation to tool setup and machining.

But a beginner with a clear production goal may have a different requirement.

Someone learning CNC specifically to make larger signs, woodworking products, or customer orders may benefit from starting with the 4040 Nova. Otherwise, the machine itself could become a limitation once the initial learning stage is over.

The important distinction is therefore not beginner vs. experienced user.

It is small projects vs. larger projects.

For Hobbyists, Consider How the CNC Will Be Used Over Time

For occasional hobby use, the 3020 Nova offers a practical balance of capability and size. It is well suited to engraving, personalized gifts, small decorative projects, prototypes, and compact parts.

The 4040 Nova becomes more attractive when CNC is expected to become a larger part of the workshop.

A maker who frequently experiments with new project sizes, creates larger pieces, or wants to develop products over time may benefit from having more working capacity from the beginning.

This is especially relevant when choosing between the two models for a long-term hobby. If the larger working area is unlikely to be used, the 3020 Nova is the more efficient choice. If project size is likely to increase, the 4040 Nova provides more flexibility.

For Metalworking, Focus on the Actual Part Size

Working with aluminum or brass does not automatically mean choosing the larger machine.

Both models use a 710W trimmer router and can be used for suitable metalworking applications with appropriate tooling, workholding, and machining parameters.

A small aluminum plate or compact component can be well suited to the 3020 Nova. A larger fixture, panel, or component may benefit from the 4040 Nova simply because it requires more working space.

For metalworking, the important question is therefore not only what material is being machined, but what kind of part is being made and how large it is.

The same principle applies to woodworking, acrylic, and other materials.

For Small Businesses, Look at the Product Line

For small businesses, the decision should be based on both current products and likely future products.

A business producing personalized gifts, nameplates, decorations, small signs, prototypes, or compact custom parts may have little need for the larger working area of the 4040 Nova.

A business producing larger signs, panels, woodworking products, relief carvings, or larger custom components will benefit more from the 4040 Nova.

The larger machine can also provide more flexibility for product development. New products do not always stay within the dimensions of the original product line, and a larger working area leaves more room for that expansion.

For production users, the most useful question is:

Does the machine fit only the products being made today, or does it also leave enough room for the products planned next?

3020 Nova vs 4040 Nova: Which One Should You Choose?

The decision can be simplified into two different use cases.

Choose the Lunyee 3020 Nova when the CNC will mainly be used for smaller projects, personal making, home workshops, learning, prototyping, or compact products. It is the more practical option when workspace is limited and the additional capacity of a larger CNC would rarely be used.

Choose the Lunyee 4040 Nova when larger workpieces are already part of the plan, when projects are approaching the limits of a compact CNC, or when the machine will be used for a growing product range or small-scale production.

There is also an important consideration for users who are currently between the two.

If current projects fit the 3020 Nova but there is already a clear plan to move into larger signs, panels, products, or production work, the 4040 Nova may be the better long-term choice.

If there is no clear need for additional capacity, the 3020 Nova avoids paying for workspace that may not be used.

Final Recommendation

The Lunyee 3020 Nova is a practical choice for compact CNC projects, home workshops, hobby use, prototyping, and personalized products. The Lunyee 4040 Nova is better suited to larger workpieces, expanding projects, and small-scale production where additional working space matters.

Neither machine is universally better. The right choice depends on the size of your projects, available workspace, and how you expect to use your CNC over time.

Choose the 3020 Nova when compactness and smaller projects are your priority. Choose the 4040 Nova when larger projects and future expansion require more working capacity.

The best CNC router is not necessarily the largest one—it is the one that provides the right capacity for the work you actually plan to make.
