What Can You Make with a Desktop CNC Router? 10 Projects for the LUNYEE 3020 Nova, 4040 Nova and 4040 Titan
LunyeeCNC
A desktop CNC router can do much more than carve a name into a piece of wood.
With the right tooling, workholding and cutting parameters, a CNC router can produce wooden signs, detailed reliefs, acrylic panels, aluminum parts, PCB prototypes, workshop fixtures and many other custom components.
The useful question is not simply which CNC router has the largest working area or the most powerful spindle.
It is:
What do you actually want to make?
The LUNYEE 3020 Nova, 4040 Nova and 4040 Titan have different working areas and machine configurations, but all three support a wide range of desktop CNC projects.
This guide covers 10 practical applications and explains how the three LUNYEE machines fit different types of work.
10 Projects You Can Make with a Desktop CNC Router
1. Custom Wooden Signs
Wooden signs are one of the most accessible CNC projects for beginners.
Common examples include:
lNames and initials
lBusiness logos
lHouse numbers
lWorkshop signs
lDecorative lettering
lWall art
lDirectional signs
lCustom plaques
CNC machining makes it easier to reproduce lettering, logos and detailed outlines consistently. Once a design and toolpath have been prepared, the same pattern can also be repeated for multiple signs.
The LUNYEE 3020 Nova is well suited to smaller signs and personalized projects. For larger signs or several smaller pieces in one setup, the 400 × 400 mm working area of the 4040 Nova and 4040 Titan provides more room.
Signs also make a useful introduction to CNC because they cover several fundamentals: workholding, zeroing, toolpath creation and finishing.
2. Personalized Gifts and Home Decor
Wood, acrylic and other suitable materials can be turned into a wide variety of personalized products, from simple engraved pieces to more detailed decorative items.
Popular projects include:
lEngraved cutting boards
lName plates
lDecorative boxes
lKey holders
lCoasters
lWall decorations
lPersonalized plaques
lWedding and event decorations
These projects work well for one-off pieces as well as small batches of customized products.
The 3020 Nova fits compact work particularly well, while the larger 4040 machines offer more room as individual pieces or production quantities increase.
Many projects follow a straightforward workflow:
Design → Create Toolpath → Secure the Workpiece → Set Zero → Machine → Finish
Once this process becomes familiar, the same basic approach carries over to a wide range of CNC applications.
3. 3D Relief Carving
3D relief carving opens up another level of CNC work beyond simple 2D engraving.
Typical applications include:
lDecorative patterns
lLandscapes
lAnimal designs
lSculpted logos
lWall panels
lArtistic reliefs
lCarved plaques
A relief carving varies the cutting depth across the surface to create a three-dimensional effect. As a result, toolpath planning and Z-axis movement become more important than they are for a basic outline or engraving.
The LUNYEE 3020 Nova provides 80 mm of Z-axis travel, the 4040 Nova provides up to 130 mm, and the 4040 Titan provides 95 mm.
Maximum Z-axis travel should not, however, be treated as maximum cutting depth or workpiece height. The practical setup depends on the workholding method, tool, material and machining strategy.
Tool diameter, step-over and cutting depth also affect the level of detail and final surface quality.
4. Acrylic Signs and Panels
CNC routers are not limited to woodworking.
Acrylic is suitable for projects such as:
lBusiness signs
lDisplay panels
lControl panels
lDecorative panels
lTemplates
lEnclosures
lName plates
Text and graphics can be engraved into acrylic, while custom outlines, openings and mounting features can be machined directly into a panel.
A control panel, for instance, can include precisely positioned openings for switches, displays or connectors.
With an appropriate cutter and suitable cutting parameters, a desktop CNC router can produce clean edges and detailed features in acrylic.
The 400 × 400 mm working area of the 4040 Nova and 4040 Titan is particularly useful for larger panels or for arranging several smaller parts in a single setup.
5. Aluminum Parts and Components
With suitable tooling and cutting parameters, a desktop CNC router can also machine softer metals such as aluminum and brass.
Common applications include:
lMounting plates
lBrackets
lSpacers
lSmall mechanical parts
lPanels
lFixtures
lCustom hardware
Metal machining requires greater attention to workholding, tool selection, spindle speed, feed rate and depth of cut than typical wood projects.
An aluminum bracket, for example, may require a very different machining strategy from a wooden sign even when the overall shape is similar. Secure workholding and material-appropriate cutting parameters are essential.
For hard steels such as stainless steel, a dedicated industrial CNC machine is generally more appropriate than a desktop CNC router.
6. PCB Prototyping
A CNC router can also serve as a practical tool for electronics prototyping.
PCB milling can be used to:
lIsolate copper traces
lDrill PCB holes
lCut prototype boards
lCreate custom board outlines
lProduce simple electronic prototypes
One advantage of CNC-based PCB prototyping is the ability to produce a simple board directly in the workshop without waiting for an external manufacturer.
Because many PCBs are relatively small, this application is well suited to a compact CNC such as the 3020 Nova.
Accurate Z-axis positioning is particularly important because isolation routing often involves very shallow cutting depths. Tool selection and machine setup therefore have a direct effect on the finished board.
7. Wooden Boxes and Enclosures
A CNC router can produce much more than flat engravings.
With a suitable CAD/CAM design, projects can include:
lWooden boxes
lTool organizers
lElectronics enclosures
lStorage trays
lHinged lids
lFitted compartments
lCustom cases
Pockets, slots, holes and contours can all be machined directly into the workpiece.
These projects also introduce more advanced CNC concepts such as tolerances, clearances and assembly fit.
An electronics enclosure, for example, might include openings for connectors, mounting holes for a PCB and a recessed area for the lid.
Here, CNC machining becomes a way to produce a functional component with dimensions designed around the parts it needs to hold.
8. Jigs, Fixtures and Workshop Tools
Some of the most useful CNC projects are made for the workshop itself rather than for sale.
Possible applications include:
lDrilling templates
lAssembly jigs
lCutting templates
lRouter templates
lAlignment fixtures
lWorkholding accessories
lTool organizers
A drilling jig is a good example. When the same hole pattern is needed repeatedly, a machined template can replace repeated manual measurements and make positioning more consistent.
The same principle applies to cutting templates, alignment fixtures and assembly jigs. A CNC router can turn a repeated manual task into a reusable physical tool.
For these applications, repeatability and accurate positioning can matter more than maximum spindle power.
9. Furniture Components and Larger Wood Projects
As project dimensions increase, working area becomes an increasingly important consideration.
A 300 × 200 mm working area is well suited to small parts, signs, decorative pieces and compact components. A 400 × 400 mm working area provides more room for larger components and panels.
Potential projects include:
lFurniture templates
lCabinet components
lDecorative panels
lJoint components
lMounting plates
lCustom brackets
lLarger wooden signs
Both the 4040 Nova and 4040 Titan provide a 400 × 400 mm X/Y working area.
A larger working area does not mean every large furniture component can be machined in a single operation. Some projects will still require multiple sections or machining setups.
However, additional workspace can reduce the number of setups for smaller furniture components and make larger workpieces easier to position.
10. Small-Batch Production
Desktop CNC routers can also move beyond one-off personal projects into small-scale customized production.
A small batch might include:
lWooden signs
lPersonalized gifts
lAcrylic panels
lDecorative parts
lAluminum brackets
lWorkshop accessories
lCustom name plates
The challenge in producing ten identical pieces rather than one is not simply the increased quantity. Consistency becomes a central part of the process.
After the design and toolpath have been tested, consistent workholding and machine settings make it easier to repeat the same machining process across a batch.
A larger working area can also accommodate several smaller pieces in one setup, reducing the number of individual setups required.
This makes a desktop CNC useful for custom products, prototypes and limited production runs rather than high-volume industrial manufacturing.

The machine is only one part of the machining process.
Material, tooling, CAM software, workholding and cutting parameters all influence the final result. The same CNC router can produce very different results depending on how the project is designed and machined.
How the Three LUNYEE Machines Fit Different Projects
The LUNYEE 3020 Nova, 4040 Nova and 4040 Titan overlap in many applications. Their different working areas and machine configurations make certain types of projects more convenient on one machine than another.
LUNYEE 3020 Nova
With a 300 × 200 mm working area, the 3020 Nova is well suited to compact projects such as:
lPersonalized signs
lSmall wooden decorations
lPCB prototypes
lSmall acrylic panels
lEngraved gifts
lSmall mechanical parts
Its compact working area and footprint make it practical for smaller projects and workshops where space is limited.
LUNYEE 4040 Nova
The 4040 Nova expands the working area to 400 × 400 mm and provides up to 130 mm of Z-axis travel.
The additional space is useful for:
lLarger signs
lLarger relief carvings
lBigger wooden components
lMultiple small parts in one setup
lLarger acrylic panels
lSmall-batch production
It provides more room as projects move beyond a compact 300 × 200 mm working area.
LUNYEE 4040 Titan
The 4040 Titan also provides a 400 × 400 mm working area, but its machine configuration is different.
Its closed-loop stepper motors and offline controller provide a different control and motion setup, while the brushless spindle offers another configuration for workshop applications.
The machine supports many of the same project categories as the 4040 Nova, including woodworking, acrylic, PCB work and appropriate soft-metal machining.
The choice between the three machines does not have to depend on a single specification. Project size, available workspace and preferred workflow can all be considered together.
Start Small, Then Expand Your Projects
The most complicated CNC project does not have to be the first one.
A simple engraved sign covers the fundamentals:
1. Designing a project
2. Creating a toolpath
3. Setting up a cutter
4. Securing the workpiece
5. Setting X, Y and Z zero
6. Running a test
7. Inspecting the finished result
Once these steps become familiar, the next projects can introduce pockets, contours, 3D reliefs, acrylic machining and soft-metal work.
The basic workflow remains similar as projects become more advanced. What changes is the required precision, tooling, material and machining strategy.
Final Thoughts
A desktop CNC router is not limited to one type of project.
It can produce personalized products, prototype mechanical parts, simple PCBs, workshop jigs and fixtures, as well as small batches of custom components.
The LUNYEE 3020 Nova, 4040 Nova and 4040 Titan provide different working spaces and machine configurations, but the starting point is the same:
Think about what you want to make first. Then choose the machine, tooling and workflow that fit the project.
Once a CNC router is viewed this way, the question changes from:
“What can this machine do?”
to:
“What can I make with it?”
