Introduction – or what is this article about?

Laser cutting/engraving technology has exploded in recent years, and now even hobbyists can get machines with power that was unattainable just a few years ago. I started with a 2,5 watt optical output, so you can imagine the huge difference the 20 watt unit in this test makes.

The almost tenfold increase in performance enables speed, precision, and use of materials that I could not have hoped for in my wildest dreams!

Algolaser is not a newcomer to the market. The company is a brand created by the founder of Ortur Laser, which has been developing and manufacturing diode laser engraving devices since 2019. Building on the success of the original Algolaser Alpha model, the improved MK2 version (Algolaser Alpha MK2) was created, which was expanded with many innovative features, while maintaining the original 20-watt power.

The advantage of modern diode laser engravers is that they are more compact, easier to handle and, most importantly, significantly cheaper than more serious CO2 lasers. The Algolaser Alpha MK2 also has features that were previously only available in the professional category. The built-in 3,5-inch color touchscreen and the Algo Operating System (AOG) allow you to use the device without a computer, directly from an SD card or USB flash drive.

The versatility of the Algolaser Alpha MK2 is truly impressive. Whether you are engraving wood, acrylic, leather, glass, ceramics or even stainless steel, the Alpha MK2 can handle it all. Its cutting capabilities are also remarkable, as it can cut through 10 mm pine board in a single pass, while cutting 3 mm plywood is an easy routine task.

Algolaser regularly updates its devices’ firmware and also has a feature that can resume work exactly where it left off in the event of a power outage. This reliability is especially important for longer engraving jobs, where an unexpected power outage can ruin hours of work.

A special advantage for users is that the device can be controlled via WiFi, supports the popular LightBurn and LaserGRBL software, and can also be controlled via its own mobile app. This flexibility allows everyone to choose the most convenient method for engraving and cutting work.

Algolaser Alpha MK2: Functionality and durability

The Algolaser Alpha MK2 laser engraver makes a professional impression at first glance. Despite the open frame design, it has an extremely stable and robust structure that ensures precise work and minimizes vibrations. The external dimensions of the device are 692 × 585 mm, while the usable working area is 400 × 410 mm, which is an ideal compromise between portability and the size of the working area.

In terms of weight, the Alpha MK2 is around 6,5kg, which allows for easy portability, but is also heavy enough to stand firmly on a work surface. Assembly is relatively simple, requiring only 19 screws and a few connectors. The kit includes all the necessary tools and parts for assembly, including a more extensive, well-illustrated user manual.

Let's take a little detour here towards assembly!

The machine's components are rigid, stable, and heavy. They have a material feel to them when you unpack them. The components and connectors all radiate quality, which is not the least of the considerations for a laser cutter/engraver.

When you unpack the parts, the task will be daunting at first, because the number of parts seems to be a lot. Fortunately, we get very detailed assembly instructions, and as an experienced assembler, I can say that it is a huge advantage that there are not a thousand different screws in the package. We practically get two different sizes, and of those, there are only two of one. All the other screws are one size, so you don't have to look for what goes where, and this shortens the assembly by a solid 10 minutes.

You can assemble the Algolaser Alpha MK30 in about 2 half hours, including the proper tensioning of the V-belts and the initial commissioning. However, I recommend that if you lack sufficient experience and/or technical skills, be critical of yourself and find a professional to help you with the assembly. I say this because you will still be working with a 20-watt laser, which can burn through more than just the tabletop.

Let's scroll down and see the machine's other capabilities!

One of the most striking and innovative features of the Algolaser Alpha MK2 is the 3,5-inch color touchscreen on the front of the frame. This display not only displays status information, but also acts as a full-fledged control center through which all work processes can be directly controlled. Next to the screen are the traditional controls: the emergency stop button, the key lock to prevent unauthorized use, and the main switch. The latter elements are extremely useful if the machine arrives in a household where children may have access.

Take advantage of security solutions, never leave the key in the machine if you are not using it and cannot supervise it properly!

The Algolaser Alpha MK2 has a wide range of connectivity options. On the side of the device, you will find a USB-C port for connecting to a computer, a standard USB-A port for USB flash drives, a power connector and an air pump connector. The device also has a built-in Wi-Fi module, which allows for wireless connection to a computer or smartphone.

The laser module provides 20 watts of effective optical power and, thanks to state-of-the-art technology, can create a focus spot of just 0,15 × 0,12 mm, which allows for extremely precise engraving. The laser module is fixed with an innovative lever mounting system, which allows for quick and precise focus adjustment using the included focus assistant. The module has an advanced cooling system, which extends its lifespan and allows for long, continuous work.

The axes run on V-rollers, which ensures smooth and precise movement. The belt tension can be easily adjusted using the tensioning screws designed for this purpose. The Alpha MK2 has a maximum travel speed of 40 mm/min, while its engraving speed can reach 000 mm/min, which is outstanding performance in this price range.

The Algolaser Alpha MK2 has well-thought-out cable routing, with anchor points for all cables and hoses, so nothing gets in the way of moving parts while you work. This not only increases reliability, but also gives the device a more aesthetic appearance.

It is very important and extremely user-friendly compared to the competition that the basic set also includes an optional air pump, which is automatically controlled and has infinitely adjustable power. This significantly improves the cutting and engraving quality and reduces the risk of fire, especially when working with wood.

Algolaser Alpha MK2 specifications

The technical parameters of the Algolaser Alpha MK2 laser engraver provide a convincing picture of the capabilities of the device. At its heart is a laser diode with a real optical power of 20 watts, emitting blue light with a wavelength of 455 nm. This power is particularly strong (although no longer the strongest) in its category and allows for efficient cutting and engraving on various materials. According to the manufacturer, the lifespan of the laser module is approximately 10 operating hours, which represents a long-term investment for users.

The focal spot size of the laser is crucial for the quality of the work. In the case of the Alpha MK2, this is reduced to just 0,15 × 0,12 mm at full power, and to 3 × 0,06 mm at 0,05% power, allowing for extremely fine detail. This precise focusing is thanks to the so-called COS (Combined Optical System) technology, which results in a significantly smaller focal spot compared to conventional systems.

Let's add that the data given at 3 percent performance is meaningless, because you can't work with that kind of performance. However, the 0,06 × 0,05 mm value looks good in marketing materials.

The working area measures 400 x 410 mm as standard, but can be optionally extended to 400 x 850 mm with the extension kit. This size is an ideal compromise between desktop usability and a sufficiently large working area. The overall external dimensions of the device are 692 x 585 mm and its height is approximately 240 mm, making it a compact design in its class.

In terms of speed, the Algolaser Alpha MK2 shows outstanding values: the maximum engraving speed is 30 mm/min, while the maximum movement speed reaches 000 mm/min. This speed is particularly advantageous for the production of large quantities of products or for large-scale jobs, significantly reducing machining time compared to previous generation devices.

As another addition, it is important to know that with faster movement, the inaccuracy will also increase, but this is not a consequence of this laser, but of the toothed belt drive, and is essentially true for all similar machines. Moreover, the engraving speed of 30 mm/min, although a fact, is essentially useless in practice unless you are engraving very soft material (such as paper or dry leaf).

In terms of control, the Algolaser Alpha MK2 is extremely versatile. The built-in AOS (Algo Operating System) operating system provides easy operation via the touch screen. The device supports the most popular control software such as LightBurn and LaserGRBL, and also has its own mobile application. Connectivity options include a USB-C port for direct computer connection and a built-in Wi-Fi module for wireless control. In addition, the built-in 32 GB SD card and USB-A port allow direct file use without an external computer.

The material compatibility of the Algolaser Alpha MK2 is remarkable. In terms of its cutting capabilities, it is suitable for processing various types of wood (up to 30 mm thick in a single pass), plywood (up to 15 mm), MDF (12 mm), acrylic (10 mm black acrylic) and other materials. It can be used for engraving on wood, bamboo, leather, acrylic, glass, ceramics, tiles, aluminum oxide, stainless steel, coated metals and dark stone surfaces. It is especially noteworthy that the device can display up to 500 different shades of color when engraving on stainless steel by changing the laser power and speed.

Safety was a top priority during the design. The Algolaser Alpha MK2 has an emergency stop button, key lock, tilt sensor, vibration sensor, and automatic shutdown function in case of USB disconnection. Together, these features ensure safe operation, minimizing the risk of fire and accident hazards. The Algolaser Alpha MK2 is factory-installed in laser class 4, but can be upgraded to class 1 with a suitable protective box, which significantly increases the safety of use.

Algolaser Alpha MK2: software

One of the most outstanding features of the Algolaser Alpha MK2 is its wide range of versatile control options. The device runs the unique AOS (Algo Operating System) operating system, which provides full control directly via the 3,5-inch touch screen. The user-friendly interface is easy to navigate, has a fast response time, and the most important functions – such as file selection, scaling, positioning, and modifying engraving parameters – are all available on it. The system is unique in that it can continue work from where it left off after a power failure, if the user has previously activated this function.

The device has wide language support, the user interface is available in several languages, although Hungarian is not among them yet. The menu system allows you to manage Wi-Fi settings, update the firmware (even directly from the Internet), and activate or deactivate various security features. The system is able to automatically offer recommended settings for different materials and engraving techniques, which is especially useful for novice users.

The device supports the most popular laser engraving software, including the professional LightBurn and the free LaserGRBL. LightBurn offers extensive design and control capabilities, including vector graphics design, layer management, and complex engraving parameter settings. The software also allows for automatic control of Air Assist during engraving and cutting tasks, which significantly improves quality and increases safety.

The new software version arrived during the test, let's see what new features it brings!

AlgoLaser has released its latest software update, AlgoOS 2.3, which significantly improves the laser engraving experience. This update adds several new features to the software that make laser engraving easier, more accurate, and more versatile for both hobbyists and professionals.

One of the most important innovations is the improved AlgoType function, which now allows you to customize text directly on the device. Previously, external software was required to fine-tune fonts, sizes and other elements, but now all this can be done directly in the AlgoOS system. This significantly reduces design time and simplifies personalized engraving.

Another notable new feature of the update is the image inversion, also known as reverse engraving. This is especially useful when engraving on darker or reflective surfaces. The program automatically inverts images, allowing for sharp and visible engraving on any colored material, whether it’s glass, acrylic, or anodized aluminum.

AlgoOS 2.3 also provides optimized support for 2W 1064nm lasers, which are specifically designed for engraving metals, stones, and certain plastics. Users now only need to select this laser type and the software will automatically set the appropriate parameters for the best results. This allows us to perform precise work on stainless steel, gold, and other previously difficult-to-engrave materials.

The update also improves on the features introduced in AlgoOS 2.2: it provides a faster and more efficient workflow, expands the range of compatible materials, increases accuracy and quality, and gives users more creative freedom. AlgoOS 2.3 is an essential update for all AlgoLaser users who want to achieve the highest level of detail and quality in their laser engraving projects with minimal effort.

Algolaser has also developed its own mobile application, which is available on both Android and iOS platforms. The Algolaser App allows you to control the laser engraver wirelessly from a smartphone or tablet. A special feature of the application is that you can send images taken with the device's camera directly to the engraver, and within the application it is also possible to easily edit and parameterize the images. This function is ideal for quick, unique engraving jobs, such as creating personalized souvenirs.

The device's internal storage and USB flash drive support also allow users to upload pre-made G-code files (or SVG, JPG, or other formats) to the device and run them directly from the machine, without a computer connection. This feature can be especially useful in mass production or in environments where it is impractical to use a computer (such as a dusty workshop). The device can store and display a preview of the engraving or cutting job, which helps with precise positioning.

Algolaser regularly updates the device firmware and related software, adding new features and performance optimizations to the device. Installing updates is easy, either directly from the Internet, or via SD card or USB. This continuous development ensures that users always have access to the latest features and improvements, extending the useful life of the device.

The communication between the control software and the device is stable and fast, thanks to the advanced 32-bit quad-core control panel with 8 MB RAM and 8 MB storage, as well as the aforementioned 32 GB SD card. This resource provision ensures smooth operation even with complex engraving jobs and allows processing of 256-level grayscale images, resulting in detailed engraving.

Algolaser Alpha MK2 in practice

Well, I've finally reached the important part, where I can report on my impressions. If I could, this article would consist of nothing else. Of course, you have to give a reason for everything, describe the specifications, assembly, etc., but, you see, the experiences part is the most important!

First impressions are very important, and there was no mistake here! The packaging of the Algolaser Alpha MK2 is extremely compact, sophisticated and eye-catching. The size of the box was much smaller than I expected, which is understandable, since the device arrives disassembled.

The components are well separated in the cardboard, so nothing can be damaged during shipping. While unpacking, I was amazed at the quality of the cabling and connectors, as well as the quality of the materials used and the assembly in general.

This was similar to the previously tested Mk2 DIY kit. And, while we're at it, there's one thing I don't really understand. In the previously tested Algolaser, the DIY label was understandable, since you have to assemble it and once you've assembled it, you have to (DIY) make all kinds of stuff with it. So it's understandable that it was DIY, but I don't understand why this one isn't. Read that article here too: We tried: AlgoLaser DIY KIT MK2 – a professional laser for beginners (even!)

So, as I wrote above, the assembly turned out to be extremely simple – based on the included instructions, I managed to put the machine together in about half an hour. The biggest challenge was fitting the individual elements of the frame, where a helping hand would have been useful, but in the end I managed to do it on my own.

Upon assembly, the robust construction of the device was immediately noticeable. Although it is not a solid aluminum frame, but consists of profiled metal sheets, it results in a surprisingly stable and rigid construction. Adjusting the shaft and tensioning the belts was easy with the tools and instructions provided with the device.

It is important to note here that correct adjustment of the belt tensioner bolts is critical, so pay due attention to this!

Connecting the Algolaser Alpha MK2 to WiFi was a particularly positive experience. After switching it on, it immediately offered the language selection option, followed by the WiFi setup. Within seconds, available networks appeared and the connection was made in a matter of moments. The firmware check and update also went smoothly, which suggests that Algolaser really takes software support seriously.

I tested the performance of the laser module on several materials. but I was basically curious about the cutting performance. I currently use 22,5- and 10-watt machines at home, so I have some basis for comparison in terms of performance.

I basically work with plywood, more often birch and less often poplar. The thickness of the birch sheets, which varies, is between 3 and 8 millimeters.

The cutting test went smoothly, cutting 3-4 millimeter sheets is relatively quick even with 20 watts in one go. Air assist is also needed during cutting, the device that came with the machine did its job very well. Speaking of air assist, it is important to highlight that the variable speed of the air pump is a useful feature.

After many trials, I started a new project, a decoration that I had never done before. According to the original plan, I should have made a plate about 60 x 60, which means I would have had to cut up the vector image to fit the pieces into the machine. Instead, I made the whole thing smaller, which resulted in the plate burning through in quite a few places where it shouldn't have because of the small patterns. I would like to emphasize that this was not the machine's fault, the laser burns the material at a wall thickness of a thousandth of a millimeter.

Overall, I can say that, similarly to the test cuts, I got extremely precise and beautiful cutting edges. Precision was also important in this case because I assembled the finished work from 4 layers. If the cut had not been precise, it would have been visible on the edges that one piece of work was larger and the other smaller. But here everything went smoothly, everything fit perfectly!

When cutting, it is worth using the maximum power, but when engraving, you can play with different powers, because depending on how much air you blow on the material, you can change the intensity of the engraving color. That is, if you use more air, the pattern will be lighter, if you use less, the pattern will be deeper and darker.

In terms of cutting, reasonable thicknesses that you will be able to handle relatively easily are 8-millimeter pine and 6-millimeter plywood. In practice, 10-millimeter pine and 8-millimeter plywood will also work, but depending on the quality of the material, there may be difficulties with these (meaning, where there is a lot of glue between the layers of plywood, the laser may not be able to cut through them).

I don't want to say much about engraving, because if the cutting works, the engraving will work too. What is worth noting is that with 20 watts, engraving stone and steel also produces good results. I used to experiment with color engraving on steel, but I didn't try it with this machine because, to be honest, I wasn't impressed with the results. Anyway, I like working with wood much more.

The touchscreen was extremely easy to use. The system responded to every touch and the menu system was logically structured. I found the built-in material library, which recommends optimal settings for different materials, particularly useful. The screen also allows for on-the-fly parameter changes, which gives you great flexibility when experimenting with different materials.

I'm including this here because I feel that the touchscreen and mobile app are basically beginners' weapons. It's not a bad weapon, but I find it a bit difficult to use the machines this way.

However, I must say that AlgoOS, especially the updated version, really dazzles us with a lot of great options. If you just want to make a single workpiece, you can use the machine via the touch-sensitive display, because it is much more convenient than using a computer. I really liked how easy it is to fine-tune the work. There are pre-set laser power and speed for different materials, but you can easily override these settings if you see fit. I also took advantage of this option, and I did the right thing, because for 4-millimeter hardwood plywood, the 200 mm speed would have been too slow.

The point is that I much prefer traditional computer control. I mostly use LaserGRBL, but for more complex tasks I use LightBurn, because with one start I can both engrave and cut materials, which makes the work much easier. Especially when it comes to the Algolaser Alpha MK2. But why? I'll describe it below!

Focusing the laser was easy with the included focusing tool, but as I have stated in several of my tests, I am not a big fan of these adjustment spacers. Especially not if there is no designated place on the machine where I can put them when I am not using them. And since I do not cut every day, and sometimes months go by without lasering, the spacers can get lost. That is really annoying!

What I really liked was the way the laser module is attached with the lever mechanism. Finally, you don't have to screw in any screws to attach it. You pull the lever down, adjust the height, pull the lever back and you're done. Well, this solution deserves a red dot so big that no one can fit in here!

My only major criticism is related to the design of the laser module: the cover is not removable, which sometimes makes it difficult to position it precisely, as it is harder to see the exact location of the laser through the dark protective glass. Well, this is why using LightBurn comes in handy, because if you do not start cutting and engraving on the same material at the same time, due to the design of the laser, you will not be able to manually align the head to the starting point for the second work session.

I'll try to explain this.

So you have a material that you engrave first and then cut around. If you do the job in two passes with the free laserGRBL, you do the engraving, then manually position the laser at exactly the right point and start the second process, the cutting.

However, this only works if you can see exactly where the laser is shining, that is, you can see the laser light on the material. Well, with the Algolaser Alpha MK2, you will never see where the laser light appears on the material, because the cover of the laser head essentially extends to the processed material, and the small viewing window is so dark that you can only see the laser light through it when the machine is working.

In short, I don't like this head design when I have to work with LaserGRBL. In the case of LightBurn, this is not a problem, since there you don't have to position the material afterwards, even in multiple work sessions, and it's not a problem if you only want to cut or engrave one thing at a time and you start the work with the machine's own software.

As I wrote above, the quality of cutting and engraving was significantly affected by the use of the air blower (Air Assist). In my experience, engraving without an air blower often produces a smoky, slightly blurred, dark pattern, while using an air blower produces clean, sharp, but fainter lines. The automatic control of the air blower with the LightBurn software worked great, although interestingly the device always maintained a minimum airflow, even when the air blower was in principle turned off. This can be a problem if you do not want to use the minimum airflow for certain engraving tasks.

Overall, based on my experience, the Algolaser Alpha MK2 is an extremely versatile and reliable tool that can be an excellent choice for both beginners and experienced users. The 20-watt laser power is sufficient for most hobby and small craft tasks, while the operation of the device remains simple and intuitive.

Algolaser Alpha MK2: Final Review

During the testing of the Algolaser Alpha MK2 laser engraver, it became clear that the device represents an excellent price-performance ratio in the current market. The 20 watts of real optical power, the extremely precise 0,15 × 0,12 mm focal spot, and the 30 mm/min engraving speed provide capabilities that were previously only available in much more expensive, professional-class equipment. The robust construction, thoughtful cable routing, and the use of quality components and connectors promise a long service life, which further increases the value of the investment.

However, the main strength of the Algolaser Alpha MK2 is undoubtedly its versatility, and the fact that it can be a really good base for a beginner, while a professional weapon in the hands of an experienced user. The touch screen control, WiFi connection, mobile app support and traditional software control options together allow for extremely flexible use, although, as I said, I find this more useful for beginners, but we are not all the same, maybe these options will come in handy for you as an experienced laser user. I should note that when making a test piece, it makes the work much easier that I don't have to mess with the computer, but can easily set up the machine and start working using the touch-sensitive display and the AlgoOS system!

What is certain is that the intuitive interface of the AOS operating system and the resume after power failure function are advantages that specifically prioritize the user experience. The device is capable of processing a wide variety of materials, from wood to acrylic to metals, which provides almost unlimited creative possibilities.

Of course, like any product, the Algolaser Alpha MK2 has its minor shortcomings. The non-removable protective cover of the laser module can sometimes make precise positioning difficult, and the minimum level of air supply cannot be completely turned off, which can be a problem for some special applications. However, these are minor things that usually do not cause significant difficulties in everyday use and are dwarfed by the advantages of the device.

One of Algolaser's greatest strengths as a brand is its ongoing product development and support. Regular firmware updates (as I wrote, a major update came right during the test), detailed documentation, and technical support suggest that the manufacturer is committed to the product and its users in the long term. This is especially important for a device that we expect to operate reliably for years.

Overall, the Algolaser Alpha MK2 laser engraver is an excellent choice for both beginners and experienced hobbyists, or even small businesses. The device's capabilities, reliability, and user-friendly design combine to provide value that far exceeds its price. Whether it's creating unique souvenirs or small-scale production, the Algolaser Alpha MK2 is proven to be up to the task and deserves a place in every creative workshop.
