G00 CNC Code Explained: An Easy Intro for Beginners [Rapid Travel]

July 23, 2023 by Brandon Fowler

Welcome to our comprehensive guide to using the G00 CNC code. Whether you’re a beginner learning CNC programming or an experienced machinist, understanding the G00 CNC code is extremely important.

In this guide, we’ll break down everything you need to know about this rapid traverse command, including how, when, and why to use it.

What does a G00 code do?

G00 sets the CNC movement mode to rapid traverse, sometimes called rapid travel.

G00 controls the speed of the machine’s motion.

This code is used to move the CNC table and/or spindle around in a straight line (linearly) at the maximum speed.

When G00 is used, the machine ignores any feed rate set with the F code and instead goes as fast as possible.

Any combination of 1 or more of the machines axes can be moved in rapid mode. This includes the X, Y and Z axes.

Because G00 is a modal code, it will stay on until you switch it to another movement mode such as G01 – Linear interpolation or G02 – Clockwise circular interpolation

Make Learning G Code Easy

G00 vs G0: Clearing the Confusion

Some people get confused about whether the extra 0 is required to be included with an G00 code.

To clear this up, there is no need to include the extra zero in the code. The CNC machine will read the code the same. It really is just a matter of preference.

Often you will see the full G00 code used in textbooks or other reference materials. In practice though, many prefer the shortened G0 code in their programs.

If you are working on your own, then go with whichever format you prefer. If you work in a bigger shop, make sure to stick to the format that the business has been using.

When to use the G00 code

G00 codes are used when the CNC programmer wants to move the tool very quickly. This happens at many points throughout a program.

Rapid positioning with G00 moves the machine at full speed. This allows the program to be run faster and decreases the part cycle time which means parts can be made faster.

G00 should only be used when there is no cutting action happening.

Using G00 while cutting your part would not give you good control over the cutting conditions and would most likely damage your part and/or your machine.

Use the G00 code to move the cutter to the location where it will start cutting or to other locations in the CNC such as the tool change position.

Other codes used with G00

The codes below are used with the G00 code or commonly found very close to a G00 command in the CNC program:

Format for using a G00 code

G00 X1.0 Y2.0 Z3.0

G00 is a simple code. You only need to specify the stop location for the movement.

Because G00 is a modal code, you don’t need to specify it on every line of code. If the next line of code after the one above was X4.0 Y5.0 Z6.0 then the machine would still move to the location in rapid mode. Because it’s modal it stays on until switched to another mode.

How to turn off a G00 code

There isn’t a specific cancel command for G00 like there is for canned cycles.

Instead, to turn G00 off you will need to switch it to another code in the same group of movement codes.

The other codes in the movement group are:

G01 – Linear interpolation

Using any of these codes will turn G00 rapid movement off and switch to the new movement mode.

What to think about when using a G00 code

Units

First, make sure you know what units you are working in.

Moving 10 inches instead of 10 millimeters is a big difference. A G20 (inches) or G21 (mm) code should identify the units you are working in before your G00 code.

Absolute vs incremental positioning mode

The second thing to know is how the machine will understand position locations.

This is determined by whether you are working in absolute (G90) or incremental (G91) coordinates. The most recent G90 or G91 code in the program will determine which mode you are in.

Absolute positioning will move from a set zero location, such as your machines home location or a specified zero location on your part.

Incremental positioning will move relative to the machine’s current position.

The images below show the difference between the absolute and incremental positioning modes. The numbers in parentheses are the locations given to the the machine to make the move.

graph paper example of absolute positioning with multiple points as examples

graph paper example of incremental positioning with multiple points as examples

Notice how in absolute mode, all locations are relative to a single location, usually either the workpiece zero or machine home location.

In incremental mode, all locations are relative to the machine’s current location.

Start and stop locations

Make sure you understand the path that the tool will take from it’s start location to the new location.

Check where you are currently position wise (X, Y & Z location), where you will be moving to, and if there is anything in between the two locations.

The G00 code will move the machine very quickly to the new location. You don’t want anything in the way or to miscalculate your stop point.

Crashing your machine is never a good time.

Machine movement

There are many different CNC machines throughout the world. Unfortunately, they don’t all behave exactly the same. For this reason you need to make sure you know your machine when it comes to how it moves, especially when it comes to rapid movement.

Some machines will move all 3 axes at once. Some will rapid one at a time.

Some machines will move the different axes at different speeds causing a “dog leg” movement where the machine doesn’t move in a single straight line.

illustration of dog leg movement on a CNC machine

Most machines will move all 3 at once, but make sure you know the path your CNC will take when using the G00 code.

It’s important to understand how you individual CNC machine will move because you need to make sure there isn’t something that the CNC will crash into in that path.

G00 [Rapid Travel] vs G01 [Linear Interpolation]

G01 is a very similar command. It also controls straight line movement, otherwise known as linear interpolation, of the CNC machine.

The difference between the two is that G01 will not move at maximum speed and will instead move at the last feed rate listed in the CNC program using the F command.

G01 is used for cutting motions. G00 is not.

Note that all the movement codes listed below are modal. This means they will stay in the movement mode identified by the code until switched to a different mode.

Code	Function
G00	Straight line rapid movement
G01	Straight line movement at a defined feed rate
G02	Circular movement in a clockwise direction
G03	Circular movement in a counterclockwise direction

Beginners Guide to Rapid Traverse for CNCs

April 5, 2023February 25, 2023 by Brandon Fowler

Key Points

Rapid traverse is full speed movement

Rapid travel and rapid traverse are the same thing
The G code for rapid traverse is G00 on CNC mills and lathes

The rapid speed can be adjusted using the rapid override

What is rapid traverse?

Rapid traverse, sometimes referred to as rapid transverse or rapid travel, is used for moving a machine tool around the workpiece as fast as possible.

Depending on the type of machine tool, this is accomplished in different ways. See below for more information related to CNC and manual machines.

How fast does the machine move in rapid traverse?

First let’s talk about speed.

Rapid traverse speeds vary based on the machine. A good quality desktop CNC will usually be capable of speeds around 100 inches per minute (IPM).

homemade cnc router machine — Homemade “garage” CNC

Larger, industrial grade CNC can often move at speeds of 1,000 inches per minute or more.

industrial cnc machine — Industrial grade CNC mill

No matter what type of CNC you are using, you will want to make sure that nothing is in the way when these moves are being made in a CNC machine.

Crashing a CNC at normal speeds is bad enough, crashing a CNC at rapid speeds could be catastrophic.

Can rapid traverse speed be adjusted?

cnc control board with rapid travel dial identified with arrow — Rapid Override Dial

Most CNC machine controls have an adjustment to dial back the rapid travel speed. This is often referred to as Rapid Override or something similar. This override allows the CNC operator to adjust the rapid speed, usually in the form of a percentage of the full speed.

Some shops need to run full speed. Time is money after all, but many machine shops will dial things back a little for safety.

How does the CNC move during rapid travel?

Newer CNCs will move in a true straight line fashion, however some older CNCs can process the command in different ways.

Some machines may only move one axis at a time while others will move in other strange ways. The most important thing is to be aware how your specific CNC control will process the rapid travel command and create your program to account for this movement.

Because various machines will process commands in different ways, this means you may not be able to take a program and a setup and run it on a different machine.

What is the G code for rapid traverse?

The G code for rapid movement is G00.

This applies to both CNC mills and lathes.

In the example above, G00 is the code for rapid traverse and the X and Y values are the position that the machine is to rapidly move to.

Rapid movement can happen in the Z axis as well.

What should you think about when using rapid travel?

When you are zipping your CNC back and forth think about:

Part location – it can be easy to forget about a step in your part and attempt to move over the top of you part at a Z height that is too low
Fixturing – similar to your part location, remember that you often have clamps, vises, etc. that will be in your machine and it’s best to avoid them
Removing material – don’t cut in rapid mode, it will result in size issues and poor surface finishes at best

Rapid traverse in manual machining

Many manual machines, such as a Bridgeport mill, use a power feed to rapidly move around the workpiece.

These power feeds are not as fast as a CNCs rapid moves but they are still much quicker than the standard speed which usually involves cranking a handle to position the machine.

Best Desktop CNC Routers for Home Use [2023]

January 7, 2023 by Brandon Fowler

Let’s face it. There just isn’t enough space at home.

We all do it. We have mountains of tools, gadgets and just plain ole stuff strewn everywhere. Sure, you can clean your garage, workshop, kitchen table or wherever you tend to work on stuff, but it just doesn’t last.

Space is at a premium, which is why we bring you our guide to the best small desktop style CNCs. While these CNCs won’t be carving up 4’ x 8’ sheets of plywood anytime soon, they are more than capable of creating some pretty cool projects on a smaller scale.

The best part is their small footprint means they can be easily stashed away when not in use. But please don’t run one in your closet. Your significant other will not approve of a sawdust and metal chips on their clothes. Don’t ask how I know.

Without further ado, check out our picks for the top desktop CNCs.

SainSmart Genmitsu 3018-PROVer

Machine Work Area: 300mm x 180mm x 45mm = 11.8″ x 7.0″ x 1.7″

Physical Machine Dimensions (Machine Footprint): 400mm x 330mm x 240mm = 15.7″ x 13.0″ x 9.4″

Weight: 21.4 pounds

Materials it Will Cut: Plywood, MDF, PCB, acrylic, nylon, carbon fiber and soft metals

Warranty: 1 Year

This SainSmart Genmitsu 3018-PROVer comes mostly pre-assembled, needing only about thirty minutes of assembly once out of the package. A smaller machine that is great for CNC beginners, hobbyists, and small business owners, this machine is very quiet and can operate inside an apartment or similar space without disturbing the neighbors. The smaller size also means it is easy to move around.

Further, the PROVer comes equipped with an emergency stop control that is very visible and easy to access for an immediate shutdown of your machine. You’re inevitably going to mess something up if you work for long enough, so having a big red button to shut off the machine is pretty helpful.

The machine also comes with acrylic safety baffles to help stop dust from spreading while you’re working, making clean up a bit easier and faster. That said, the machine does produce a lot of dust and wood chips, so you may want to make your own cover, or at least be prepared for a thorough cleaning after use.

This 3018 PROVer comes with an offline controller, which allows you to run the machine without having a computer attached.

Though the machine is not particularly wide it can be used to make pass-throughs for narrower, but longer pieces.

Even though it is a smaller machine, it is built using solid materials. Rather than being made out of wood or plastic, like a lot of cheaper models, the PROVer is made with aluminum. This solid construction also helps reduce noise and vibration while the machine is working.

MYSWEETY DIY CNC 3018-PRO

Machine Work Area: 300mm x 180mm x 45 mm = 11.8″ x 7.0″ x 1.7″

Physical Machine Dimensions: 400mm x 330mm x 240 mm = 15.7″ x 13.0″ x 9.4″

Weight: 15.82 pounds

Materials it Will Cut: Wood, bamboo, paper, ivory, leather, flammable plastic, PCB, acrylic, ceramic/stone, metal surface paint, metal surface plating

Note: DO NOT work on metal, iron, glass, 201/304 stainless steel, jewelry, or silver

Warranty: 1 Year

One important thing to understand with this machine is that it is truly a machine made for CNC beginners. If you expect to get this in the mail and begin a large project, you’ll be somewhat disappointed. With that said, it is a good machine for those who want to start learning CNC.

Though the machine does not come assembled, assembly is relatively easy, taking between one and two hours. If you need some extra help, there are plenty of videos on YouTube that can assist you.

That the machine does not come pre-assembled is not a surprise given its price point, but, again, assembly is easy so don’t let that discourage you.

Initially, it may seem worrying that the frame of the machine is plastic – plastic can easily snap and break if the machine is running a hard job that causes vibrations and shaking.

However, the plastic framing is phenolic resin, meaning it’s really strong stuff that will not break easily. Such strong plastic also means that there are fewer parts needed for assembly, which is of course a bonus.

It should also be emphasized that the machine defaults to metric movements, so if your code is in inches and you manually move the machine with the offline controller you will run into some issues. So, you either have to be really careful when the machine is operating and be prepared to do conversions on the fly, or you can just make sure that your code is done using the metric system.

Lastly, one shortcoming of this machine is that it is mainly only for engraving on wood. This machine does not do all that well for any cutting action.

If you’re looking to engrave harder materials – such as soft metals – this machine is probably not for you. It does have the added benefit of working well for laser engraving.

For those who might want a multipurpose machine, the MYSWEETY CNC makes a good choice. The easy to use laser engraving software means most will be able to set it up and start engraving in short order (remember your laser safety glasses).

CNC work will take a little more effort because the included CNC software isn’t as user friendly, but is still very manageable.

Genmitsu PROVerXL 4030

Machine Work Area: 400mm x 300mm x 110mm = 15.7″ x 11.8″ x 4.3″

Physical Machine Dimensions (Machine Footprint): 641mm x 755.5mm x 580mm = 25.2″ x 29.7″ x 22.8″

Weight: 57.2 pounds

Materials it Will Cut: wood, MDF, plastics, foams, vinyl, and aluminum.

Warranty: 1 year

The setup for this machine is really nice. All of the hard bits – such as routing the wiring – are done for you, so what’s left only takes about an hour if you’re working hard. Maybe two hours if you’re going through it at a slow pace.

Once you get started, you’ll notice that this machine definitely has a lot of torque. It’s probably a good idea to start off with the 3018 model if you’re a true beginner, but if you have just a little bit of CNC experience this is a well-built, powerful machine. This model comes with a super rigid structure, so you shouldn’t have any difficulties with it in terms of vibrations and shaking once your work starts.

Because the PROVerXL 4030 is so powerful, it can work on a fairly wide range of materials. You can work on wood, MDF, plastics, foams and even aluminum. Some users have said that they can also cut other soft metals, though if you’re not experienced with soft metals you shouldn’t try to work with them on this machine.

In terms of workspace, if you’re doing relatively small projects there should be plenty of room to work. For beginners, or even a small wood/metalworking business you should have enough space to do virtually any CNC project for your customers within reason.

But if you are looking to do something a bit larger, there are some really nice upgrade kits that you can purchase for this machine. For more working space you can buy additional sizes 24”x 24”( 600 x 600mm), and up to 40” x 40” (1000 x 1000mm).

For even more versatility in terms of what you can make with this machine, you can buy the Rotary 4^th Axis or High Powered Laser Modules.

VEVOR CNC 3018 Router Kit

Machine Work Area: 300mm x 180mm x 45mm = 11.8″ x 7.0″ x 1.7″

Physical Machine Dimensions (Machine Footprint): 400mm x 300mm x 240mm = 15.7″ x 11.8″ x 9.4″

Weight: 17.1 pounds

Materials it Will Cut: All types of plastics, soft aluminum, woods, acrylics, PVC, PCB

Warranty:

The biggest advantage of the VEVOR 3018 is its price. Generally coming in at a little more than $100, you’re going to get a ton of value out of this machine. Of course, a cheaper machine generally means fewer capabilities and cheaper materials, but the VEVOR 3018 is still a good CNC machine for beginners.

Speaking of its construction, the frame is mostly aluminum with some plastic in there as well. For a cheap machine, having an aluminum frame is a big bonus. Metal frames help to reduce vibration, which makes the machines more accurate.

One downside for this machine is its assembly. You have to do most of the work yourself, and the assembly guide comes with only pictures, no words. However, there are helpful videos that you can find on YouTube to help out.

Generally, this machine should only be used for engraving, as it is not the strongest machine on the market. You may be able to cut through some balsa wood, but don’t try anything stronger than that. Some users have said that if you push the VEVOR 3018 to its outer limits the machine begins to shake a fair amount, so that is one thing to keep in mind as well. However, if you’re using the machine within its normal range it is pretty quiet.

Generally, people have seemed to have good interactions with the manufacturer if they’ve had any issues, so that’s always a bonus.

Overall, if you’re okay with installing the machine using only pictures and YouTube, then this is a good introductory CNC machine if you do not want to spend a lot of money. But remember, you get what you pay for.

Things to consider when purchasing a desktop CNC

Safety

Just because these are entry level machines does not mean they aren’t powerful and cannot hurt you. Always read instructions. Also, some of these machines can cause a lot of dust and particles to fly into the air while they’re operating, so you should wear safety glasses if you’re getting close.

Size of work area

The size of the work area for any machine directly affects the size of the project you are capable of doing with that machine. All of the machines on this list are entry level, so they are not particularly large. That means they can be easily moved around and do not take up so much space, but that also means the projects you are capable of producing is limited.

It’s also important to remember that the overall size of the machine is not the same as the work area of the machine. For example, the SainSmart PROVer 3018’s overall size is 420 x 340 x 280mm, but its work area is only 260 x 155 x 35mm. That’s a big difference, so make sure you’re reading the machine specs carefully.

Machine construction

This relates to the materials the machine is made out of. When a machine has a really solid frame – typically made out of metal, like the Genmitsu PROVerXL 4030 for example – this is always preferable to a frame made out of wood or plastic.

A solid frame will reduce the shaking of the machine, which makes cuts and engravings more accurate. Reduced shaking can also make the machine quieter when it’s running.

Work materials

Not every CNC machine will cut all materials. This is especially true when it comes to smaller, desktop style CNCs.

There are two big jumps in capabilities. The first is to soft metals such as aluminum. The second is to harder metals such as steel.

Some of the machines above will handle aluminum. Not all will do it easily. None of them will be able to cut steel.

Take note of the capabilities of each machine as referenced above and you won’t be disappointed.

Tooling

Tooling is another word for cutters. Different materials require different cutters, and the type of cutter you’re using can make all the difference on a project.

Most machines will come with a few cutters for you to use right away. These bits are not usually of the highest quality, but if you’re a beginner they will do the job. Learn the pieces, and when you’re ready you can buy separate, more expensive ones.

Customer service

Customer service is really important because these are complex machines if you’re new to CNC. It’s not uncommon to have an issue during assembly, or while you’re using the machine.

In many online reviews, people note the level of customer service that they have experienced, and you should pay attention to this. Don’t be afraid to go on a company’s website and look around to see how easy it is to contact customer service, and also look for things like video tutorials that the company has provided themselves.

CNC software

There is a large variety of software that gets used on these machines. Covering them all would be a giant topic by itself. To get you started here is a quick rundown:

CAD or computer aided drafting is software that will allow you to create models to machine or engrave. This is only a drawing and needs further processing before your machine will know what to do with it. The most commonly used CAD software are Fusion 360 and Tinkercad
CAM or computer aided manufacturing is the software that takes your model and turns it into code that your CNC will understand. If you are familiar with 3D printers, CAM software is similar to slicing software. The most common CAM software are Fusion 360, CamBam, SheetCam and MeshCam.

A good starting point is to look into Fusion 360. It has an enormous number of tutorials on YouTube. You are likely to find help for any issue you run into and there are many guided courses on use of the software.

CNC routers vs spindles

When it comes to beginner level CNC machines, the terms router and spindle are used almost interchangeably. Some machines, such as the ones from BobsCNC, use an actual router like you would buy at a hardware store. Others use spindles.

Practically, they are both motors that have a collet or chuck to hold a cutting tool such as a router bit or end mill.

Machine Size: 990mm x 810mm x 530mm = 39” x 32” x 21”

Weight: 42 Pounds

Materials it Will Cut: Wood, plastic, soft aluminum, acrylic, PCB, leather, others are possible with experimentation

Warranty: 60 Days

While still an entry level machine, BobsCNC machines are a cut above the rest. Their machines are typically more heavy duty, capable of cutting more materials, and are more expensive than other entry level machines. While this machine can cut a large variety of materials, including soft aluminum and leather, CNC wood routing is easily BobsCNC’s specialty.

When looking at the E4 machine, you should be aware that setting the machine up will take a good deal of time. Unlike most other beginner CNC machines, the E4 does not comes pre-assembled.

You should plan on assembly taking up most of an entire day. Keep in mind, though, that when assembly is this intense, you really get to know a machine well, which will be super helpful if you’re a beginner.

Additionally, the instruction manual is highly detailed and thorough. The assembly isn’t necessarily difficult, but instead is simply time consuming. Luckily, if you come upon any roadblocks, you can find an abundance of guidance on YouTube and Facebook to help you along.

But if you are facing any big obstacles during assembly – or even long-after you’ve got the machine running – BobsCNC has a great reputation for top notch customer support and service.

Call or email them, and you are guaranteed to get a quick response, and a simple solution to whatever problem you may be facing. As a matter of fact, Bob himself has been known to respond to users seeking help frequently.

Keep in mind that this is a big and powerful machine. As such, it can create more noise than other, smaller entry level machines. It can also create a large amount of dust and chips when it’s working, so be sure to have a shop vac ready to clean up or better yet, a dust collection system in place.

The E4 is the type of machine that you would normally want to store in a garage or workshop instead of inside your main living area.

This is a heavy-duty machine and you can expect it to be louder and a bit messier, but because it is such a solid machine you can also expect it to perform quality work for a long time to come. The E4 is a real workhorse, and many customers have found the machine to last for ages.

The BobsCNC Evolution 4 is an excellent option for a woodworking CNC. The setup will take more time than our other recommended options but there is a substantial payoff in the end. The expanded work area and power of the machine will allow a much larger variety of work than smaller machines.

SainSmart Genmitsu 30018-PROVer

Work Area: 300mm x 180mm x 45mm = 11.8” x 7.1” x 1.7”

Machine Size: 400mm x 330mm x 240mm = 15.7” x 13.0” x 9.4”

Weight: 21.4 pounds

Materials it Will Cut: Plywood, MDF, PCB, acrylic, nylon, carbon fiber and soft metals

Warranty: 1 Year

If you’re looking to get your feet wet with CNC machining, but don’t want to jump all the way in quite yet, then the SainSmart Genmitsu 3018-PROVer is a good place to start.

For a sub-$400 machine, you get a lot of value from the PROVer.

For one, the 3018 PROVer will arrive at your door largely pre-assembled, so you won’t have to spend too much time putting the machine together.

It might take you longer to put together than the 15 minutes that SainSmart advertises, but you should be able to put this together fairly quickly, and there are plenty of YouTube videos out there to give you a hand if you get stuck.

While this machine is pretty powerful for a beginner machine, one common review from users is that it is fairly quiet. If you live in an apartment and you don’t have to worry about your neighbors making a noise complaint, the 3018-PROVer makes a great option.

Another great feature of the PROVer is the aluminum frame. For a budget priced machine, having a sturdy metal frame is a big bonus.

A solid frame helps to reduce any vibration from the machine, which makes the machine more accurate, and works to reduces noise.

Along with the aluminum framing, the machine has acrylic safety baffles which help stop dust from spreading while you’re working, making clean up a bit easier and faster. A welcome addition for anyone who plans to run this CNC indoors.

Another great feature of the PROVer is the easy to see, easy to access shutdown button.

This big red button on the side of the machine makes triggering an emergency shutdown super simple. From experts to amateurs, mistakes are going to happen, so such an obvious emergency stop button will come in handy. This is a feature that all full blown industrial CNCs have and for good reason.

When you hear something start to go wrong with your run, and trust me, you usually hear it before any other warning signs. The stop button just might save your project or cutter tools.

Other safety features of the PROVer include hard stops, and limit switches to keep the machine from coming off the rails, literally. The limit switches will tell your machine to stop safely when your custom CNC program attempts to move the cutter three feet off your dining room table.

SainSmart has done a good job including many of the 3018 series CNC upgrades and accessories that people find they want after purchasing such as an offline controller, which will allow you to run the machine without needing to have a computer attached.

Overall, the 3018 PROVer is a top notch, entry-level machine that is especially useful if you’re looking to start smaller wood carving and wood cutting projects and is more than capable of tackling other materials of similar hardness.

The MYSWEETY 3018-PRO is truly a beginner CNC router for woodworking. The machine is easy to get started with, but it can’t handle some of the difficult materials that more powerful CNC routers can. Luckily, all can be forgiven when you look at the price.

If you’re looking for something to introduce you to the world of wood cutting and wood carving, the MYSWEETY will do that and more.

While this machine does not come pre-assembled like some other models, putting it together is not all that difficult. Set up time should take most people between one and two hours.

Setup is made even easier because there is a large selection of videos on YouTube that can help guide you through the process.

The machine’s frame is primarily made out of metal, so you know it is going to be sturdy. But even the gantry (crane type bridge), which is made of plastic is solid. It is made using phenolic resin, which is extremely strong stuff. For a CNC woodworking machine on the cheaper end of the price range, the MYSWEETY is surprisingly well built.

The MYSWEETY also has the benefit of being ready to laser engrave wood projects as well as CNC routing. Unfortunately, the machine has an issue where the laser module’s focus lens fits loosely. This can make it too easy to accidentally turn resulting in poor engravings from the laser not being focused properly.

No worries though, a small bit of Teflon tape on the threads will allow you to fix this problem yourself.

The biggest downfall of the machine is that it does leave a little bit to be desired if you want to work with something beyond wood.

It is just not all that powerful, and you shouldn’t try to push this machine too far. It will work well with wood and softer materials but don’t expect it to work well with even soft metals such as aluminum.

All in all, if you’re looking to get started with CNC routing and woodworking as a hobby, this is a good machine for just that. The laser engraving module makes a big plus as well.

The MYSWEETY CNC is a budget friendly option that is capable of producing some pretty cool woodworking projects.

Genmitsu PROVerXL 4030

SainSmart has created one of the most recognizable introductory CNC machines with its 3018 PROVer. Everything that SainSmart has been able to pull off with their flagship 3018 CNC has been replicated and upgraded on the PROVer XL 4030.

More power, more work area and more options for increasing the capabilities of the machine down the road as branch out into different projects.

Like the smaller 3018 PROVer, the 4030 comes mostly pre-assembled. Assembly is easily accomplished, just don’t expect it to take the 15 minutes that SainSmart quotes it at.

Not only is this 4030 CNC one of the best woodworking CNCs available but it is also one of the most common. This means there are plenty of quality YouTube videos to help you along the assembly process and beyond should you run into any stumbling blocks.

All in all, the SainSmart 4030 can be assembled, fired up and be cutting or engraving in no time at all.

As mentioned earlier, this machine is powerful. A great benefit that many lower end machines don’t have.

While the PROVerXL isn’t an industrial shop-level machine, if you’re a hobbyist or a small business owner you should still be able to get some good mileage out of this CNC.

The PROVerXL 4030 will cut a wide assortment of hard and soft woods, as well as plastics, foam, vinyl, and even aluminum. Keep in mind that if you plan on working with materials on the harder end such as aluminum, they will likely take more trial and error whereas you’ll find it difficult to run into trouble working with wood of any kind.

This machine also has the structure to match its power. The frame is made entirely out of aluminum. The rigidity this provides helps that you don’t sacrifice power for accuracy. With the 4030, you won’t have to worry about vibration or shaking which can result in poor surface finishes or decreased accuracy, even if you’re engraving metals.

As far as workspace goes, this machine is definitely bigger than the 3018, though in its original form you’ll still be limited to relatively small projects. However, there are some really nice upgrade kits that you can purchase for the machine.

Kits to expand the machine work area to 24”x 24”( 600 x 600mm), and up to 40” x 40” (1000 x 1000mm) are available. And for even more versatility in terms of what you can make with this machine, there is a rotary 4th Axis and a high powered laser module available as well.

If you want to get started with CNC woodworking and have the ability to work with more difficult materials in the future, the PROVer XL 4030 is the right machine for you. It also makes a great upgrade for those who are already familiar with the 3018 series because the added power and capabilities will expand what is possible to make with your CNC.

Things to consider when purchasing a woodworking CNC

Assembly

CNC routers will come in a variety of assembly stages. Some machines will come almost entirely assembled for you, while others make you put together every last part.

For some people, assembling a machine is part of the fun. Many times, it can help you learn about your new tool.

For other people – especially beginners – you will want something that is practically ready to use out of the package. Preferences will differ but keep this in mind when reviewing the different options available. Assembly difficulty is certainly a factor to keep in mind.
