Folks tend to ask me quite often which of the three laser cutters -- GlowForge, Flux BeamBox, Flux Beamo -- I like and what are their differences. So in Facebook I have been writing comparison posts, but the posts eventually get pushed down and forgotten. So I decided to copy/paste my comparison write-ups here where I can keep them current and updated. This "little" article may have some repetition. I will return to it and will try to consolidate all the topics. But until then, enjoy!
As both an owner of a Glowforge (by Glowforge) and Beambox and Beamo (both by Flux), I tend to do comparisons for myself as I migrate work between these machines. These are laser cutters capable of either cutting or engraving on a vast number of different materials. I like both brands -- Glowforge and FLUX Inc.. Both machines will do amazing work laser cutting and engraving. Some things with the Glowforge is easier than with the Flux machines. But to be fair, don't forget that the Glowforge was in beta for about 2 years before backers received their machines (I was one of the early ones) and that was three years ago. The Glowforge is a very polished machine, very easy to use. The Glowforge UI, being web based, is very different than Flux's Beam Studio, which is more of a traditional software package. Some tasks are easier to do with the Glowforge -- such as scoring -- and the engraving feature has more options, such as dithering a dot pattern or line pattern. With that said, I have not yet downloaded the latest beta of Beam Studio and it seems there might be some dithering options now.
The Glowforge, BeamBox, and Beamo are all well built machines and work well for all the laser cutting we do, and we do a lot of laser cutting. All the machines have their differences, especially the obvious: the sizes. But in terms of the what they can cut or engrave, everything has been pretty much the same. The 30 watt Beamo has been keeping pace with the 40 watt BeamBox and Glowforge with the materials we commonly use, which is wood and acrylic.
Another thing about the Glowforge UI is that I can have the Glowforge do a laser cut while I open another browser tab and begin setting up the next job. So far with the Beam Studio (Flux) software I haven't been able to run two instances at the same time. Beam Studio can control both machines, but not at the same time. It is fairly easy to switch between them, but I have not been able to do a laser cut job on both machines at the same time from one Beam Studio instance. The way I get around this is to have one computer per machine.
The laser cutters by FLUX Inc. (BeamBox and Beamo) are very good machines that so far are proving very reliable to me. The onboard camera I find is more accurate than the Glowforge, Both the Beambox and Beamo are physically connected to my network via a cable instead of wifi as the Glowforge is. Although I tend not to have connection issues on my end of my wifi, there's been a few times where the Glowforge servers are congested. When this happens you can't do any laser cutting as the Glowforge requires connection to their servers. This may not be an issue for many, but if you intend to have a Glowforge in a garage or workshop, it needs a reliable wifi, and then you are still at the mercy of server congestion.
Both the Beambox and Beamo are quiet compared to the Glowforge. I can use either of the two FLUX laser cutters at 2 AM without disturbing anyone (as I was doing last night). But one thing, seems to me that the Glowforge has better airflow. Smoke seems to get pulled out very quickly. The Flux machines do have decent airflow, though.
The FLUX machines require filling a tank with water every-so-often for cooling the laser tube. The Glowforge does not as it is a closed system that doesn't allow you access, and the liquid is an oil instead of water.
Replacing the laser tube for the FLUX machines can be done by yourself, but the Glowforge requires sending the entire machine back.
Other things, the Glowforge has automatic focus, but you can manually enter material settings if you want to. There's a bunch of other settings with the Glowforge UI, tools to help replicating various tasks, and a premium service for other features you have to pay extra for. You can draw basic shapes with the Glowforge UI, but I think that is one of the premium services -- it is currently offered to me as a free trial. The Beam Studio has drawing basic shapes built in, and I find the FLUX's tool for arraying a design via rows and columns extremely useful.
The Beamo also has automatic focus, but this is an extra add-on you purchase separately and connect it yourself. The Beamo (and BeamBox) also have other add-on's, such as a rotary attachment for engraving cylindrical objects, such as glasses and drink tumblers. The Beamo also has a diode attachment. No rotary tool or diode attachment with the Glowforge. Other Glowforge models have a pass-through feature, though, for large materials.

They both started on Kickstarter.
GlowForge, an American company, had a kickstarter that we decided to pledge. At the time we had no idea what we would use a laser cutter for, but the low price was good enough that we decided to take a risk. Early Bird slots were already taken when we were pledging, but we were able to get the next one or two early pledge levels. The machine was in beta for a long time and lots of folks started to think Glowforge was a scam. The machine was passed around for reviews and made convention appearances. By the time the laser cutter was released a good two, maybe three years had passed. But the GlowForge machine was a work of art -- easy to use, easy to set up, and results were amazing. After years of waiting we were pleased we got a very polished machine. We can only imagine that during those years the folks at Glowforge spent their time optimizing everything about the machine.
FLUX is a company based in Taiwan. They got their start with a Kickstarter campaign for the Flux 3D Delta printer. The printer turned out to be a well designed and reliable machine. We pledged for this 3D printer and became pleased with the quality of the machine itself and of the prints. The Kickstarter was handled very well with timely responses and good organization. We also got to see the quality of the customer support. After the Kickstarter ended and everyone got their machines customer support didn't take a back seat. Software was updated quickly and problems were engaged even by the owners themselves. There were rough spots, though (as expected from a company starting out). When customer support started to have problems (mostly long delays) the folks at FLUX took action and updated the support company. With all this we saw that the Flux owners were serious about the company and their reputation. It was also obvious there was a passion involved, especially with the owners taking part in the forum discussions. So when FLUX started a new kickstarter event for a laser cutter, the BeamBox -- a large, 40 watt machine similar in size to the Glowforge -- we decided to support them again.
A year later FLUX did another kickstarter campaign for the Beamo -- a much smaller, 30 watt laser cutter. Again we pledged.
So we went through three kickstarters for FLUX and one for Glowforge.
Without getting into the numbers, the Glowforge is a long, large, mostly plastic, machine. The top and cover is glass. The corners are curved. There is only one single button to control the machine. The rear has an exhaust vent and the power on/off switch. What we bought is the 40 Watt Glowforge Basic. The weight is around 70 lbs and visually it looks good -- like high tech furniture. We get the impression the Glowforge folks are Apple fans as their kickstarter video uses an Apple laptop for demonstrating the software and the ability to engrave the surface of a laptop. The minimalist styling somewhat has that "inspired by Apple" aesthetic.
The BeamBox and Beamo are similar looking machines. The BeamBox is much larger than the Beamo, on par with the Glowforge. The shape is more angular and the machine itself is heavy. The body is made of steel and feels much more heavy duty than the Glowforge even though it is also a 40 Watt machine. Where the Glowforge will look well indoors near the kitchen, the BeamBox looks more appropriate in a workshop.
The Beamo has a similar appearance to the BeamBox. Similar shape, but a lot smaller; it can fit on an office desk. The Beamo is a 30 Watt machine. Although 30 Watts might not seem like a lot, it is plenty good for the types of projects we do. It cuts all the different woods we use easily, has no problem cutting the acrylics, and no problem cutting plastic, especially the plastic used in 3D printing. Sometimes we engrave on cork and the Beamo is great for that.

UI and Wi-Fi/Connectivity
Web Based: One of the good things about the Glowforge is the UI -- the User Interface. The Glowforge uses a web based UI, it is essentially a web page. There are pros and cons with this, but in terms of just the UI, it is easy to control the settings to the machine. There are a lot of nice features the Glowforge comes with and the web based UI is intuitive and easy to learn. The Glowforge is indeed a very polished machine.
However, there are some drawbacks, specifically that the UI is web based. It's not too bad if you have a reliable internet connection, but if you are going to use the machine in a workshop or garage that gets poor Wi-Fi then that may be a problem. There is no way to physically wire the Glowforge to an internet router like can be done with the BeamBox and Beamo. The GlowForge requires Wi-Fi for just about all things. As soon as the GlowForge is turned on the machine will want to home -- do it's basic calibration routine -- and that's the only thing that does not require a wi-fi connection. To do a "print" (as the Glowforge folks like to call it) you have to upload your file to the Glowforge's servers then wait for the UI to change to a different screen showing how your design looks. When you're ready to begin clicking a button/link will send the file to the Glowforge servers for processing your settings. Then the servers will send back toolpath information and your Glowforge will be ready to begin. You will have to then physically press the button on the Glowforge itself to begin laser cutting.
Requiring only a wireless connection introduces other aspects that can contribute to down time: server congestion is one of them. We tend to have a steady internet connection on our end, but a few times we can't use our GlowForge because the GlowForge servers are congested, or there's some other thing going on between us and the GlowForge servers. It doesn't happen as often these days as it used to, but it can and did. During the COVID-19 lock down in the US and stay-at-home, we experienced down time with the GlowForge due to not being able to connect to their servers.
Beam Studio: FLUX uses a different approach for the BeamBox and Beamo. The UI is split between software you keep on your own computer (the Beam Studio) and a convenient touch screen directly on the machines. With Beam Studio, you install it on your own computer. It's got all the tools needed to establish a connection to BeamBox and Beamo, including calibration, setting up the camera, etc. To begin work you simply open an SVG file (GlowForge also uses SVG files (and PDF's if there's a glitch which happens from time-to-time) and arrange the design on the canvas/work area. Different settings, such as laser power/strength and speed/duration is assigned to layers. When you save your layout you save it locally on your computer.
The Glowforge UI also works in the same way as the Beam Studio for assigning settings to layers. Both software uses color as a layer. So, for example, red might have one setting, green another setting, and so on.
The Flux laser cutters have a touch screen that displays information about the current status of the machine and makes it easy to adjust/tweak a task live as the machine is working. With the touch screen you can change the speed and intensity of the burn and pause the job, or abort the job, all while the laser is doing it's thing. Nothing like that exists for the Glowforge. The Glowforge has a single button as the only physical aspect of the UI: If there's a problem the button glows a different color and pulsates. To start a job you have to press the button. But with the BeamBox/Beamo the touch screen has good features for maintenance -- running the water pump, testing the air pump for the air assist, and networking settings.
Start and Emergency Stop, Pause
For all of the laser cutters, if a job is currently going on you can stop the job at the machine by lifting the lid. There is a sensor for both brands that will interrupt the job immediately. However, with the GlowForge, lifting the lid will cancel the job. With Beambox/Beamo lifting the lid will pause the job. You can then resume at the menu screen on the machine or at the software.
With the Beambox and Beamo, you can start a job at the software too. After setting up the items you want to laser cut, both brands have a button in the software to send the job to the machine, but only the Beambox/Beamo have the ability to begin the laser cut through the software. The GlowForge requires a physical button press on the machine itself to actually begin.
When it comes to design, I use 3rd party applications, such as Affinity Designer and SolidWorks. But if you really wanted to, you could use the UI for the laser cutters to draw primitive shapes and text. This feature is standard with Beam Studio, but I believe this is a feature currently on free trial with Glowforge, intended for a premium service.
Work Area Layout:
Both brands have a camera under the lid somewhere. The GlowForge has a camera directly under the lid and it is much faster than the Beambox/Beamo to take a snapshot of the work area. But the Beambox/Beamo camera is more accurate once it's calibrated. I don't remember if I had to calibrate the Glowforge's camera during set up. The camera for the Glowforge uses a fish-eye lens and some interesting math to approximate object placements at the extreme edges of the work area. The Beamo/Beambox camera is near the laser nozzle. Requesting a snapshot using the software requires the user to draw an area of interest to take a snapshot in. The laser machine will move the nozzle/camera throughout that area taking a series of thumbnail size photos. The result is not as clean as the GlowForge's camera, but it is more accurate. There is also the tendency with the Beambox to experiences pauses with the camera or to lose the last few snapshots. So far I have not experienced that problem with the Beamo.
With the Beambox you have to keep the laser tube cooled with distilled water, so have to always make sure the water tank is sufficiently filled. The Glowforge uses an oil and comes already filled. Laser tubes have a shelf-life and will require replacing eventually. With the Beambox you can replace the tube yourself -- Flux has already posted videos how to do this. With the Glowforge the company encourages to ship the entire machine back to the company for tube replacement, and that costs $500. You can replace the tube yourself, but don't expect help from Glowforge, and if you screw up, you'll have to send the machine back anyway. So if you do get a Glowforge, keep the original shipping box. Glowforge wants folks to ship back in a Glowforge shipping box, and it's a $240 charge to get a new one.
Some of the GlowForge features are subscription based. The features for using the UI as an editor with drawing and text functions is a premium offering. There's a few more features with the GlowForge that you can not use unless you have a subscription. For me this is worrisome since designs that are going to be laser cut have to be uploaded to the GlowForge servers. With subscriptions being tested for certain features currently going on, what might that become in the future? With GlowForge, every design that is going to be cut is uploaded, then that design stays on the GlowForge servers until you explicitly choose to delete it. For for any one user there is a lot of space being used on the servers and right now that space is unlimited for every one. But will that always be so? Subscriptions, along with being web-based cloud centric, introduces an element of uncertainty. Folks often voice the concern that being web based anything can happen -- the company can go under, for example -- and you won't be able to use the machine. While this is true, it is more possible for company policies to change, and then suddenly there's restrictions where restrictions did not exist before.
The Glowforge UI now has the ability to save your design to your local computer.
Flux's Beam Studio is more of a traditional software package that is installed locally on your computer. Your designs are opened within the application and you can make setting adjustments, and save locally. Internet is not required other than to download updates. Likewise, there is no subscription with Beam Studio.
