In this review, I take an in-depth look at the latest Nomad CNC machine from Carbide 3D, the Nomad 3.
Nomad 3 was brought out as a major improvement to the highly popular Nomad 883.
The Nomad 3 CNC router is a turnkey solution for those who want to get straight to cutting as soon as they receive it.
The machine comes preassembled and contains all the tools, software programs, and accessories needed to get cutting within an hour of opening the box.
You can use it to make small parts with very high precision and speed making it a good choice for jewelers, and for small prototyping.
The Nomad 3 is also the best budget PCB milling machine on the market.
It is also designed to be a useful tool for engineers, crafters, hobbyists, and manufacturers of custom products.

Carbide 3D Nomad 3 Review
I reviewed Nomad 3 after carefully evaluating it for its build quality, ease of use, features, software package, compatibility, assembly time, community, and official support.
Nomad 3 has a footprint of 19” x 17.5” which is similar to that of a small office copier and is 17 inches tall.
It weighs around 65 lbs which means you can keep it on your desk and stove it away on your shelf when not in use.
You can mill workpieces with a size of up to 8” (200 mm) x 8” (200 mm) and a maximum thickness of 3 inches.
The limited size means the nomad 3 is ideal for people working on small workpieces which need precision work.
2. Material Capability
Nomad 3 can cut a wide variety of soft and hard materials.
You can mill Bamboo, Softwood, Hardwood, Plywood, MDF, Cork, Graphite Limestone, HD Wax on the Nomad 3.
It can cut plastics like ABS, Acrylic, Delrin, HDPE, Kydex, Nylon, Linoleum, Polycarbonate, Polypropylene, PVC, Styrene, Sintra, and Resin.
Further, it has also been tested with composites like AL/PVC panel, Carbon fiber, Garolite, Foamcore, and Renshape.
You can also mill metals like Aluminum, Brass, Lead, Magnesium (Fire Hazard), Steel (Using Coolant), and Titanium(Using Coolant) on Nomad 3.
The maximum feed rate possible on Nomad 3 is around 150 ipm, but that is for non-metals.
For metals, the feed rates are below 20 inches per minute and it goes as low as 6 ipm for titanium at depth of cut of nearly 0.01”.
Nomad 3 is a good choice for PCB making however if you only need to make PCBs other affordable machines can do a similar job at less than half the price.
The advantage of Nomad 3 is the diversity in terms of materials it can cut.
You can also use Nomad 3 for making small 3D figurines using the flip jig accessory.
I talk about it more later in the accessories section of this article.
3. Aluminum Milling on Nomad 3
Nomad 3 can cut through aluminum stocks at shallow depths of cuts without any lubricant.
As an example, the feed rate while cutting aluminum at a depth of 0.01" is around 40 inches per minute (ipm) for a profiling cut.
You can cut aluminum with a much better finishing on Nomad 3 when compared to the earlier model-Nomad 883.
4. Chassis/Frame of Nomad 3
Nomad 3 has an all-metal frame made of aluminum that has excellent rigidity and that makes this CNC router suitable for cutting small metal stock.
The nomad is quite heavy considering its footprint and that helps in damping vibrations.
The overall build quality is sleek and sturdy.
I personally love the aesthetically designed body of Nomad 3 which comes in three different color options, grey, white, and wood.
Additionally, it comes with an enclosure and door.
The enclosure is transparent on the front side and has transparent windows on the side which lets you monitor the cutting process.
The enclosure is a nice addition as it helps keep the noise levels low and prevents milling dust from spreading onto your workspace.
Additionally, it also makes cleaning much easier.
5. Linear Motion
Nomad 3 uses a lead screw-driven mechanism with anti-backlash nuts on all three axes, this provides good precision and responsiveness.
Nomad 883, the predecessor of Nomad 3 used a lead screw mechanism without anti-backlash and was prone to backlash error.
Backlash is inherent to lead screw mechanisms and can affect accuracy, however, the anti-backlash nuts on the Nomad 3 make sure the backlash is insignificant.
The gantries move on linear guide rails, linear guide rails are more accurate and efficient than V-wheel based systems.
This is a major difference between the Nomad 3 and Shapeoko CNC router, as Shapeoko uses a V-wheel based system instead of a linear guide rail.
6. Spindle on Nomad 3
The spindle used on Nomad 3 is significantly different from the one used on the previous version of Nomad (i.e Nomad 883).
Nomad 883 used a 10,000 RPM spindle which has been replaced with a 24,000 RPM spindle on Nomad 3. This means the material removal rate of Nomad 3 will be more than double of Nomad 883 which reduces the cycle time.
It is a 130W spindle with a variable speed between 9,000 and 24,000 RPM.
When you are using small diameter tools, the material removed per revolution is very less compared to larger diameter tools.
In such cases having a high-speed spindle will allow you to make more cuts per minute which will improve the overall material removal rate.
Slow spindle speeds are used for large diameter tools, Nomad 3 uses tools with shanks less than 1/4" and it is good to have high spindle speeds for such tools.
One major point of complaint about the Nomad 883 was that the spindle was underpowered, and Carbide 3D seems to have solved that issue with a new powerful spindle in Nomad 3.
You can use ER11 collets with the spindle that can hold tools with a maximum shank diameter of 7mm.
However, the collet is not included with Nomad 3 and you will have to buy it separately.
7. Controller and Electronics
Nomad 3 uses an Atmel 328 based board with GRBL firmware flashed onto it.
The controller has four stepper drivers of which only three are used on Nomad 3.
This is because Nomad 3 uses the same controller used on the Shapeoko that uses four stepper motors.
You can connect the controller to your computer via USB cable and use Carbide Control software to control the machine.
Nomad 3 is rated at 130 W and can work with a 110V or 220 V supply with a maximum current draw of 2A, meaning you can plug it into any standard 110 V socket in your house or office.
Nomad 3 features an automatic tool length measurement feature that helps you zero the Z-axis after each tool change.
It has inductive homing switches on all three axes.
Inductive switches are contactless switches and these prevent the axes from crashing into the frame.
The homing switch allows you to automatically home the device through the control software.
Carbide 3D has also installed an induction switch on the door, which detects whether the door is closed or open.
If the door is open the machine does not start and stops if it is running. This improves the safety aspects of the machine.
However, this also means that you cannot operate the machine with the door open. This can be needed when you need to use a vac or lubrication system for cutting metals.
If you need to work with the door open, you can find how to do it from other users who did it from the community forum.
For easy edge finding, Carbide 3D provides their BitZero V2 touch probe.
The BitZero V2 can be used to automatically zero all three axes to the corner point of the workpiece on the Nomad 3.
However, it will require you to have Carbide Motion 5.14 or higher for automatic zeroing.
Another upgrade from the Nomad 883 is the internal illumination. When you lean over to look at the small parts being cut, your body can cast a shadow on it. The LEDs inside Nomad 3 provide good illumination in such cases.
8. Software for Nomad 3
Carbide 3D provides four software programs with Nomad 3 which covers all the software need for Nomad 3 and does not require you to purchase additional software.
Carbide 3D provides a free license for MeshCAM V8 CAM software with the Nomad 3.
If you were to buy MeshCAM separately, it'll cost you $250.
You can create G-code from STL files using MeshCAM and use it to run Nomad 3.
The version of MeshCAM software provided with Nomad 3 can only create G-code specific to Nomad 3 and you cannot use it to work with any other CNC machines.
MeshCAM can be installed on Windows and Mac/OSX computers and is an offline software.
Nomad 3 comes with a redeemable code that can be used to obtain a free license to Alibre Workshop.
The license is non-transferable, which means if you redeem the code and you decide to sell your Nomad 3, you cannot transfer the free license to the person buying Nomad 3 from you.
Alibre Workshop is a powerful 3D CAD/CAM package and has a simple design that lets you design and generate G-code with the least number of clicks possible.
It is easy to learn and also includes a simulator using which you can predict any errors before cutting your stock.
However, it only works on Windows computers and does not require an active internet connection to function.
This is the primary software to control Nomad 3 and is free to use for Nomad 3 users.
You can install Carbide Motion software on Windows and Mac/OSX computers and it will work without an internet connection.
Carbide Motion is feature-packed and lets you control Nomad 3 in full auto and manual mode.
It lets you visualize your cuts before actually making the cuts on Nomad 3.
Carbide Motion has a minimalistic and easy-to-use user interface.
Carbide Create is a 2D design software developed by Carbide 3D and it is bundled free of cost with every purchase of Shapeoko or Nomad CNC machines.
You can use it to create 2D designs easily by using preset shapes available in the library.
Carbide Create is so easy to use that a person with little design experience for CNC can create complex designs.
It is easy to learn and it can generate G-code that is relevant to Nomad 3. It also seamlessly integrates with Carbide Create to give you a smooth cutting experience.
Carbide Copper is the CAM software for PCB making on Nomad 3.
The software has an innovative interface and lets you create prototypes in no time.
However, it is a web-based software and requires you to have an active internet connection to use the software.
Carbide Copper is fine-tuned to work with Nomad 3 CNC machines it runs smooth and fast.
All the software package that comes with Nomad 3 are free to use and you do not have to pay any subscription fee for any of them.
Low Profile Vise
If you need a vise to hold down your workpieces you can purchase the low profile vise accessory from Carbide 3D for around $120.
It is 2” wide and 8” long and has a clamping width of 6.5 inches and comes with the hardware needed to attach it to the worktable of Nomad 3.
You can use it to hold workpieces from the side and it is also a good work holding option for holding cylindrical workpieces.
Nomad Threaded Table
If you want to use screw-down clamps to hold your workpieces you can purchase the threaded table accessory from Carbide 3D for around $120.
However, you’ll lose around ½” of the available Z-axis height by adding the threaded table.
This accessory has 73 M6x 1 threaded holes in it and comes with clamps and five M6 screws to attach to Nomad 3.
Nomad Flip Jig
This accessory allows you to hold the workpiece by the edges and cut both sides by flipping the entire jig once a side is complete.
It is a must-have accessory if you want to make small 3D sculptures using the Nomad 3.
You can use stocks that have a size less than 3” x 5” and with a maximum thickness of 1.2 inches.
Nomad 3 has a built-in machine calibration to locate the Flip Jig on the table and hence you do not require edge finders.
There is practically no assembly involved with setting up your Nomad 3.
Nomad 3 is shipped pre-assembled and all you need to do is connect three wires, install the collet in the spindle, and install the wasteboard.
The only time you spend will be in downloading and installing the software on your computer which you can even do before Nomad 3 arrives.
With a few basic adjustments and configuration, you can start making chips in less than 30 minutes of unpacking your Nomad 3.
If you need help in setting it up, there is an excellent instruction manual provided with the kit that will help you through the process.

A quick comparison of Nomad 3 and Shapeoko 4
Comparing Nomad 3 and Shapeoko 4 is probably an apples and oranges comparison.
But if you're wondering about which to get, I'll help break it down for you.
The short answer is that it depends on your need.
If you are a craftsman making small intricate objects, Nomad 3 is the better choice and if you are a woodworker making cabinets and furniture, Shapeoko 4 is the obvious choice.
The tradeoff is between size and accuracy.
If you need to work on large workpieces Shapeoko 4 XXL has a work area of 33" x 33" compared to the 8" x 8" work area on Nomad 3.
The Shapeoko 4 standard has a work area of 17.5" x 17.5" and the XL version has a 17.5" x 33" work area.
A Shapeoko 4 would clearly be better if you need to work on large materials.
As for materials, Nomad 3 can cut a multitude of materials at a faster speed than Shapeoko 4.
This is because of the all-metal design of Nomad 3 which gives it good rigidity to cut faster.
It can also cut 3D objects using two-sided milling techniques with the help of the flip jig.
Nomad 3 is a small machine and can fit inside the trunk of your car allowing you to take it anywhere and it is rigid enough that you need not worry about tramming or losing accuracy when you transport it.
For linear motion, Nomad 3 uses lead screws with anti-backlash nuts on all three axes which give it rigidity and excellent precision when compared to Shapeoko 4.
On the other hand, Shapeoko 4 uses a belt drive on the X and Y axes which are less precise than a lead screw. Even though the Z-axis uses a lead screw, it does not have an anti-backlash nut which makes it prone to backlash errors.
This means Nomad 3 is a more accurate CNC machine than the Shapeoko 4.
But this doesn't mean the Shapeoko 4 is inaccurate, far from it.
When you are working on metals and small objects you need to be highly accurate compared to say a woodworking project.
Nomad 3 has an automatic tool length measuring probe and also Nomad 3 is completely enclosed.
On the Shapeoko 4, you will need to purchase these separately.
The spindle used on the Nomad 3 is less powerful than the router used on Shapeoko 4, but a spindle can run for a longer duration than a router.
Another major difference is the assembly time. Nomad 3 is ready to run out of the box, whereas Shapeoko 4 requires quite a few hours of assembly and calibration before you can start making chips.
In conclusion, it all depends on what you need from the CNC router.
If you want a machine to plow through large workpieces, you need Shapeoko 4.
However, if you want excellent precision on small workpieces of up to size 8" x 8" x 3" along with good cutting speeds, you need the Nomad 3.

Frequently Asked Questions (FAQ)
How do you zero Nomad 3 with the door open?
Nomad 3 has a door interlock feature that prevents the machine from running with the door open. You need the machine to work when you are zeroing and the door needs to be open for giving you access. Carbide 3D provides a key that you can place on the inductive door open sensor and it will prevent the sensor from activating and allows the machine to run with the door open.
