## Customer Reviews

### ⭐⭐⭐⭐⭐ A few annoyances and shortcomings, but otherwise, it cuts, it carves, it slices and dices...
*by D***. on July 11, 2022*

Having used numerous little 2W and 5W laser etchers over the years (though this is my first AtomStack machine) that were mediocre at etching and could only cut 2mm basswood with a dozen passes (if then), I was a little hesitate to try this laser, worrying it wouldn't be much better. But, I'm really glad I decided to get this. If you don't want to read this entire review, the quick summary is that despite a few shortcomings, this thing works and it works well. If you have basic mechanical skills at assembling things, have reasonable expectations on what such lasers can/can't do, and exercise proper safety with lasers, I doubt you'll be disappointed with this machine. Here's a quick pros/cons list, which I will expound on in this review:Cons:- No packing list showing what items should be in the box- Wrong power cord was sent (EU style instead of US)- Assembly instructions sparse, and in some cases, slightly wrong for optimal assembly- Touchscreen comes up in Chinese as the default language and doesn't first prompt you to set your language on first startup- Touchscreen responsiveness and touch target sizing issues- No way to do manual machine commands from the display without having a carve-file- WiFi security issues- Touchscreen and WiFi/Smartphone App are unnecessary trinkets with limited usefulness and add unnecessary cost to the machine- Little thought was given to cable management in the design- Y-Axis ruler is no where close to the workspace area- Not sure how safe the safety glasses it came with are with this laser- Couldn't find the firmware files posted online for this specific model (maybe it's just too new?)- No specs on the processor or board it uses in their datasheet, except to say it's a "32-bit micro"Pros:- Very fast shipping- Well packaged to avoid shipping damage- Decent X/Y Axis design with good tolerance and mechanical stability and parts were cut square- Came with a SD Card and USB SD Card reader- Included sample carving files and material to do initial testing- Fixed Focus distance- Speaks GRBL protocol and thus works with most all open-source software apps- Seems consistent with the power and feedrate settings reported from other reviews online, including non-Amazon sites- Cuts and etches quite well- Compared with the performance of my 5W diode lasers, it seems to really be a 20W laserWhat I ordered: Having worked with a few lasers before and knowing how important air assist is to cut quality, I decided to go with the A20 Pro model, which has the better F30 air assist, as the better air assist doesn't seem to be available separately, unlike the rotary axis add-on, for example. I also got the AtomStack B1 Laser Enclosure (Amazon #B09TF9291N), which does fit this laser (at least as well as it would fit any other similar AtomStack laser, but that's a separate review). And I got the 18.5"x17.32"x0.87" (440 x 470 x 22mm) Dewallie Honeycomb (Amazon #B09NVDTLPH), which has a 400 x 400mm working area. It has the side clamps and has a properly spaced undertray for venting smoke and vapors (which is also very important for cutting) and was the better choice over the AtomStack and other brand honeycomb options for the price. It works well, with this laser, by the way, and fits perfectly -- just be sure that the wing nuts for the clamps are turned so they don't collide with the Y-axis.The machine actually arrived much sooner than I thought it would. When I ordered it, it was still showing in preorder status, since this was a brand new device and still in early manufacturing stages. I ordered it on Wednesday, June 29th. The enclosure arrived on Sunday July 3rd. That was good, because it gave me a couple of days to get it assembled before the laser arrived. The laser, though not shipped by Amazon, arrived Wednesday July 6th, delivered by FedEx, just one week after I ordered it, even though it said it wouldn't arrive until the 12th-18th. I was impressed by their prompt and free shipping.The unboxing: AtomStack products seem to be boxed very well for shipping, with ample packing material to hold things and not get damaged. Just be sure you dig through all of the packing material to make sure you have all of the pieces and parts out, as it would be very easy to miss something. The first issue with it was that there was no packing list of what was included in the box in any of the manuals or documentation included. Before starting an assembly project, I always like to sort out the parts and make sure I have all of the pieces. There was a main instruction manual and two additional leaflets that were essentially addendums to the manual. Though written in five languages, none of them had a list of what was included in the box. To get the list, you have to go online to the AtomStack website, which was annoying.The next issue I had was that they had sent the EU style power cable for the power supply instead of the US style, and there was no option to select the cable style on the Amazon listing when ordering. It uses a standard IEC C13 cable, of which I have plenty lying around, so it wasn't a show stopper, just a little annoying as well.The assembly instructions and pictures are a bit sparse, somewhat confusing, and lack detail. However, it's not difficult to assemble if you have ever worked with any similar device, like a 3D printer or CNC mill, etc. It only took a few minutes to assemble and went together easily with no issues. In fact, the only eccentric spacer that I even had to adjust was the one on the X-axis, which they had tightened to keep that axis from moving and sliding around during shipping.The Y-axis just slid right on and was in near perfect adjustment out of the box. However, you will want to ignore the instructions on one detail. The arrow on the instructions shows sliding the Y-axis on from the front. But if you do that, the pulley wheels will hit the Y-axis endstop switch and you'd have to completely remove them to get it on from that direction. Instead, you should slide it on from the back side.They included three wood squares and three acrylic squares for doing your initial tests and setup. And it even comes with a 4GB TF/microSD Card and a microSD USB card reader for your computer. The card had two sample .nc files to do your first cutting/engraving on those pieces of material. The card also has the instruction manuals in PDF form, plus material parameter tables listing optimal cutting and engraving settings for various materials, which were not included in the printed material (so be sure to check those files out). And it also had the software installers for LaserGRBL and LightBurn. However, the software versions were a bit out-of-date, so I recommend getting those from the web instead.The LCD touchscreen interface is a bit of a trinket, as is the WiFi link and smartphone app. When I first powered it up, the display was in Chinese mode and it didn't prompt for the language to use as the first-time power up sequence. And since I can't read Chinese, it took a bit for me to navigate the menus and find the language setting. Though if I had read more of the manual before trying, it might have gone quicker.My first disappointment with the screen was the touchscreen itself. It behaves like a lower-end resistive-style touchscreen (vs capacitive) and doesn't have the best response. Additionally, some of the targets for finger presses are too small, meaning you'll often click the wrong thing. For example, on the list of files from the SD card for engraving, you have to be very careful not to click the wrong filename or you'll have to keep clicking 'back' and trying again. One file took me five or six tries to click the correct one.Despite the touchscreen being a little finicky, my real beef with the screen interface was that it was overly basic and lacking functionality. You can't do anything on the machine with it unless you have a SD card installed with files on it that it can carve. I was expecting a menu option that gave you basic control over the machine for things like homing, setting the zero-position, moving X and/or Y axis, etc. You can do those things, but only once you've selected a file for it to carve from.This meant during the assembly, for me to test things out and see if it was working, I had to go find my laptop and connect it to the USB port. Luckily, I already had a program that could send GRBL commands to such devices, so I didn't have to install any software first, but the average user would have to install software first to even see if the motors move and the endstops work.Though I suppose, thinking back on it as I'm typing this, I could have inserted their SD card and just selected a file as if I were going to carve something. But it's still annoying not having a set of full machine controls directly on the menus that are independent of carving any specific file. For me, especially given the software I will be using (see below), without any basic machine control functions, it means I will probably never ever really use the screen for anything during normal use, making it an unnecessary "trinket".As for the WiFi and smartphone app connection, first I need to say I have not actually tried it, but from every description, the smartphone app appears to be nothing more than a secondary "trinket" screen not much different than the one on the machine itself. My concern, however, is how they describe its WiFi working in the "App Manual" (one of the aforementioned addendums to the main manual).Basically, the laser acts as its own WiFi hotspot that you connect your smartphone device to. Here's what the manual says about that hotspot: "The engraver hotspot name is: Engraver_nnnnn. “nnnnn” represents a five-digit number, which is the identification code of the machine;" and "The engraver hotspot password is 12345678, and all engraver hotspot passwords are the same;". There is no indication in the manual that the password can be changed and there seems to be no way to turn off this hotspot and there's nothing on any of the menus I can find even related to WiFi. It appears the WiFi stuff only shows up on the status screens of the display after a connection is made.This means that anyone walking by while you have the machine on with a smartphone and who happens to know that magic password can completely control and takeover your engraver, making it a security risk!! Thus, I label the whole WiFi/Smartphone control thing another "trinket" that it could do without. I will probably be clipping its WiFi antenna and/or removing the WiFi board from it entirely (I haven't opened up the controller yet to see what options exist there, but that's on my list).The laser appears to run GRBL, or at least speaks the GRBL protocol, meaning that nearly any of the many open-source laser and CNC software tools out there can communicate with it. For me, that's essential, since I run Linux (see below for my software details). It also responds correctly to device configuration requests, meaning your tools can query the machine for X/Y working size, feedrates, acceleration limits, laser value operating range, etc.While basic assembly and installation is very straightforward, it seems they put little or no thought into cable management. If you carefully position all of the cables and the air assist hose, it is possible to use the tie-wraps they included to tie them to the correct parts of the machine so that they move with the gantry and don't get tangled up or in the way, but there's nothing like a drag chain and you have to be a bit careful with that part of the setup. You particularly need to strain-relief the cable from the control box where it passes the Y-axis endstop to keep that Y-axis endstop stub from getting tugged and pulled every time the cable moves and breaking prematurely. For this, I used a larger tie-wrap (longer than those provided) and secured the cable to the side of the Y-axis extrusion just past the point where the X-axis crossbar's pulley wheels would collide with it.And the ruler markings on the Y-axis are completely off of the actual work area. It's like they shifted the markings for it in the wrong direction when trying to account for the side the laser is on. Reversing that piece would get it closer, but you can't just reverse it because then the Y-axis endstop switch would be in the wrong spot. So it's installed correctly, just it totally misses marking out the actual workspace, making it somewhat useless. Luckily, the Dewallie honeycomb I got has its own ruler markings. The X-axis ruler, however, is pretty close.I do really like the fact they they chose fixed-focus for this laser, as other etching/cutting diode lasers with the adjustable focus was always a pain to deal with. Fixed-focus is more how tube lasers, like my CO2 laser, work. There is, however, no automatic Z-axis adjustment mechanism and you don't stand a chance in manually changing the Z-axis between passes, such as to refocus to a deeper cut height for multi-pass cuts. For really thick materials, your best bet is to remove the shield on the bottom of the laser head and aim the focus below the top surface, but still above the mid-point.I'm not sure how safe the safety glasses it came with are for this laser. There didn't seem to be any test specs or proper certification documentation on it. I played it safe and used a "Made in the USA" pair from a company that manufacturers industrial laser safety devices/PPE and has very clearly defined test specs and data. Lasers aren't toys and eye safety is an important topic that shouldn't be taken lightly.I couldn't find any data on the company's website about the exact microprocessor or board set used, except for it saying that it was 32-bit. Similarly, I didn't see any firmware files posted for this model. Perhaps it's just too new of a model and the site hasn't caught up yet? One of my to-do items will be to disassemble the control box and learn more about its inner workings and setup and perhaps read out the existing firmware for safe keeping.The laser doesn't have its own software, which is good, no need to reinvent the wheel, but they mostly expect you to use either LightBurn or LaserGRBL. LightBurn, while it works on the "big three" platforms, isn't open-source and isn't freeware. They offer a free 30-day trial, but after that you have to buy a license. It also doesn't seem to support architectures like a Raspberry Pi either. So, I haven't bothered even trying LightBurn.LaserGRBL, though, is open-source and a decent program. Unfortunately, though, while you can compile it natively on Linux using Mono, it will not run due to some of its MSVC dependencies. For more details on that, search their GitHub repository issues for Linux builds. It will, however, run under Wine on Linux, but not completely. You can use it on Wine to communicate with the laser and send an existing g-code/.nc file to it, but it just hangs when you try to load a raster graphic file for etching to convert to g-code/.nc. Thus, the only way to use it on Linux to create etching files from a picture, that I've found, is to run a Windows VM on Linux and use LaserGRBL inside the VM. It does work, though somewhat mediocrely, with vector files.The best tool I've found thus far for creating vector-based carving files is Inkscape with the J Tech Photonics plugin/extension. It's quite flexible and does an excellent job if you are wanting to do cutting (the primary thing I use this laser for). Etchings, however, I'm still searching for the best-tool on Linux. There are a couple of candidates out there, such as a plugin/extension for Repetier-Host from the 3D printing world that was used on the BoXYZ CNC/Laser/Printer combo that can create etching files, works on Linux, and could be modified for this laser. But it too is a bit clunky, so I'm still searching for a best-solution for etching. For vector files for cutting, it's hard to beat Inkscape and the JTP plugin and is my go-to software tool on Linux for this.For communicating with the laser and sending the files created by Inkscape, etc., on Linux, LaserGRBL does work well enough under Wine to do that. But, the better tool I've found is Candle, which is also open-source. It does a much better job in visualizing the cut paths in real-time and is written in Qt, which is a very portable window toolkit and works on nearly every platform, meaning it can be compiled to run on a Raspberry Pi, and it has become my go-to tool for communicating with this laser.Another tool that could be used with it is CNCjs, which is an open-source GRBL fluent Javascript/NodeJS tool that works on the RPi as well as desktop and laptop PCs. It's mostly for CNC devices, like mills and lathes (I use it frequently on my MaxNC CNC mill), but it should also work for laser cutters/etchers too. And for cut-path visualization, CAMotics, another open-source cross-platform tool, works fairly well too.The bottom line, I really like this AtomStack A20 Pro laser. It's going to make a good tool for my workshop. It will be interesting to see how well it holds up over time, such as the life-span of the laser particularly under higher power loads, but so far I have zero regrets in this purchase decision.

### ⭐ Caught on fire
*by S***R on September 4, 2022*

Caught on fire and burned out the product, table and device.

### ⭐⭐ Bad from factory. Substandard internal components. Dealer support below par.
*by Y***N on August 12, 2022*

Nice looking product. This was an immediate need. Was looking forward to it. Out of the box, rattling inside air assist. Assembler must have over torque small and short screws. Pumps rattled around inside knocking parts off and cutting wires.This should be product recall. If air assist is noisy, most likely loose already. IT is only matter of time, This is substandard stuff. Product shipped from NJ, but power cord adapter came from china. Substandard power cord. Sparks every time you plug and constantly falls off. Control booted in chinese characters, with partly english.Too many issues. Was looking forward to using atomstack. I guess I go to XTool or Neje this time. Have an epilog CO2 laser. Several years of industry laser manufacturing (Amada). I am very disappointed with atomstack. This dealer shoulders a lot of these support failures while atomstack for using substandard materials.It would not be fair to review the machine itself as I never fired it. The biggest lose here is TIME. The dealer danced around issues instead of mitigating them in a timely manner. Making promises that cannot be kept. I was willing to fix it, but they could not even support me for that. They told me to tighten loose screws. Now, the return is approved, but the shipping is still within 5 days, all that time the dealer hangs on to money which I need to buy a different one.On top of that... I am 2 weeks delayed into a project. The cost adds up.I DO NOT recommend LEKU Brands nor Atomstack.
