- Intro With features like Automatic Laser Focusing,
Automatic Engraving Resuming even after a power failure, and an impressive engraving
speed of 54000mm/min, the newly launched ATEZR L2 truly sets itself apart in the saturated
CoreXY form-factor laser engraver market.
When the official Atezr team contacted me with the L2 prototype, I couldn't contain
my excitement to give it a try and share all the exciting details.
So, let's dive into it!
- Assembly This is what’s all included in the box.
We have a set of plate components, along with a 24w laser module (they also offer 36w and
48w options to choose from).
And here's the interesting part—a nifty air assist that we'll talk about in a moment.
Plus, there are screws and cables, but enough about those.
Let's get to the assembly!
First, we connect the plates by aligning them properly and pushing them in.
Then, we use screws to tighten the plates.
Each corner requires four screws, so this might take a little while.
Here's a handy tip: don't tighten them fully at first; half tightness is sufficient, just
in case we need minor adjustments later.
Once all four plates are perfectly positioned, we can go ahead and fully tighten them.
Now, it's as sturdy as a rock.
The next step is a bit tricky and may require some skill: installing the optical shaft.
We pull down the sliding blocks on the Y-Axis to the bottom, insert the shaft from one end,
and let it go all the way into the coupling.
To ensure the shaft is fully inserted, we can even push it from the starting port.
After that, we securely tighten the shaft.
But we're not done yet—while rotating the shaft, we notice another screw hole on the
other end, and we tighten it in the same way.
With that done, as we move one sliding block, the other one moves simultaneously since they
are connected through the installed shaft.
Now it's time to install the X-Axis beam.
We place it onto the sliding blocks, open the cover, and tighten both ends.
Next, let's connect the cables—one for the laser module and the other for the X-Axis.
Once connected, we carefully place them in the slot, close the top cover, and secure
it with screws.
Oh, and don't forget to attach the side covers!
They give our machine a nice look.
On the left side, where there's an air pipe, make sure to let it pass through the hole
in the cover.
Moving on to the next step: installing the Limit Switch.
We align it with the two holes as I've shown in the video and tighten it.
It's not too much of a hassle.
After attaching the laser head to the X-Axis beam, the rest is easy—all you need to do
is connect!
We connect the cables, and yes, there are a few cables for that.
Oh, by the way, don't forget to connect the air assist to the laser module through that
pipe and then connect the assist to the laser engraver.
And then we connect the screen using the HDMI cable.
This is a 4.3-inch touchscreen that can be conveniently attached to the side magnetically.
This touchscreen is a helpful accessory, and we'll talk more about it in a moment.
And voila!
That completes the assembly steps.
Simply follow the instructions I've listed above, and you'll breeze through it.
I won't lie, it took me about 20 minutes to assemble, which is pretty normal for a coreXY
laser engraver, especially considering the multitude of unique features the ATEZR offers
that others don't.
Besides, this is a one-time process.
Once you've assembled it, just leave it there for future use without any worries.
- Tutorial
Speaking of that, let's dive right in and start using it!
First, connect the machine to the power source.
Insert the physical key to unlock it, and press the power button to turn it on.
Watch as the screen lights up with anticipation.
Now, you can place the material you want to engrave or cut under the laser head.
If you're cutting something, make sure to have a trusty metal plate between the material
and the desk—just take a look at the dent we left there!
As expected, the Atezr L2 supports popular software like Lightburn and LaserGRBL.
That's just one of the three ways it supports.
The other two are the Phone App and Offline engraving.
The official Atezr team mentioned that the phone app is currently under development and
will be available in the near future.
As for offline engraving, we'll discuss that when we get to the touchscreen.
Patience, my friends!
Speaking of Lightburn, I won't delve into every single detail since there are countless
tutorials out there.
Just watch a few, make a couple of tweaks, and learn the ropes, and you'll be able to
achieve basic engraving in no time.
It's an incredibly powerful software suitable for both newcomers and experienced enthusiasts.
Before we finally get to the engraving test, you might be wondering about how to focus
for this Atezr L2.
Well, I have to mention this Autofocus feature as I haven’t seen this on any other laser
engravers I’ve tested before.
Regarding how to set the Autofocus in Lightburn, although they provide a detailed tutorial
in their manual, I'll still guide you through the process.
First, we select a Macro key, rename it to Autofocus, and enter the command brackets
[ESP500] in the contents.
Once confirmed, we can simply click on Autofocus, and the machine will take care of the focusing
automatically.
The laser module will initially bounce up and down to calibrate, then determine whether
to move up or down based on the height of your engraving material.
Once the sensor touches the surface of the material, it will confirm the focus twice
and then move to the perfect height for engraving or cutting.
It's fascinating to watch the Autofocus feature in action as it handles the focusing process
itself.
Please note that the Autofocus travel distance is 40mm, so if your material is beyond this
range, you may still need to manually adjust the focus.
However, in my tests, it handled almost all engraving scenarios.
Just in case you prefer or need to do manual adjustments, they offer a Fixed Focus Block.
Simply place it on the surface of your object, let the laser head touch it, and then remove
the block.
This is a common method for manual focus adjustment.
- Engraving ability Now that we've covered the basics of the Atezr
L2, you may be aware that it's a well-polished laser engraver with some cool features.
But how does it perform in the real world?
Well, I've conducted several tests on wood, which I believe is probably the most common
material for anyone.
The results are simply fantastic.
With a precision of 0.01mm, the engraved pictures look amazing, retaining many intricate details.
Take a closer look at the edges—they are incredibly smooth without any waviness.
I even tried engraving a QR code on 304 stainless steel.
Can you guess what it leads to?
Yes, it's my channel, and if you haven't already, please consider subscribing and turning on
that notification bell!
Although my time with this unit was limited, I believe that with more time to fine-tune
the parameters in Lightburn, you can achieve even finer results on various materials.
But personally, I believe the greatest performance of the Atezr L2 lies in its cutting ability.
I took a 20mm piece of wood and cut it four times, and it managed to handle it effortlessly.
From my experience, such a powerful laser can cut up to 15mm of wood in just one pass.
So can imagine that any small DIY cutting task would be a breeze for the L2.
Remember the Air Assist I mentioned earlier?
It vigorously blows away the smoke as the engraver cuts, just look at the smoke coming
out from the side—impressive, right?
This feature ensures a clean cutting surface.
Take a look for yourself!
- What seperates it from the rest?
Auto Z-Axis Sinking But that's not even the key feature I'm talking
about when it comes to cutting!
I'm not sure if you've noticed, but as it cuts, the laser head automatically sinks,
providing more efficient and precise cutting compared to many others without this feature.
It always maintains a constant distance between the cutting surface.
How cool is that?
Engraving resuming after power loss Speaking of surprises, this is one of the
standout features of the Atezr L2.
It offers a range of unique features that I haven't seen in other laser engravers, setting
it apart from the crowd.
Let's talk about engraving resuming after a power loss.
To utilize this feature, you need to copy the files to a USB and connect it to the laser
engraver.
We click "Start Engraving" and then disconnect the power.
As you can see, the engraving process stops.
Now, let's take a closer look at the engraving we just paused, we can check if there are
any breakpoint in the final engraving.
After reconnecting the power, we click "OK" on the screen to resume the engraving.
It automatically returns to the point where it left off.
And here is the result—pretty impressive, right?
The engraving is seamless, and we can't even find the breakpoint.
This feature deserves a big thumbs up.
Offline Engraving Another feature I have to mention is the offline
printing, which is perfect for bulk engraving.
You don't need to connect to a laptop or a phone app.
While this is not a new concept, it's much easier to use with the 4.3" touchscreen.
Speaking of that, let me give you a full walkthrough of what you'll find on the screen.
On the home page, you'll see the Engrave and Settings interfaces.
Clicking on Settings allows you to choose different languages and select different modes.
There are also safety options like Tilt Detection, which beeps to warn you if the machine tilts
over 15°, and Flame Detection, a great safety feature.
Additionally, you'll find settings we discussed before, such as Autofocus and Resume Engraving.
The third page provides information about the machine, including firmware details.
Moving to the Engraving interface, you'll find a list of engraving files that you've
copied to the USB drive.
All the files will be displayed on this screen.
That's the basic functionality of the screen.
The official Atezr mentioned that they might make changes to the user interface for the
official release, so keep that in mind.
With this convenient screen, everything becomes much easier to operate.
Having such a large screen is not common for laser engravers, right?
So when you want to engrave, simply click on the file you want, and you're good to go!
Now, let's talk about some other features the Atezr L2 offers.
It includes LED Laser Energy Display, which features several LED indicators on the laser
head.
When the laser is at full power, the color turns red.
The Cross-Positioning Autofocus is another great feature.
It marks the starting point of your engravings so you always know where it is.
Lastly, the Atezr L2 comes with a rotary extension, allowing you to engrave cylindrical objects
and small round items like rings.
- Conclusion Now, let me conclude my thoughts.
After several days of testing, I can confidently say that the Atezr L2 is an excellent investment
for anyone in need of a reliable and precise laser engraver.
It offers advanced features such as Autofocus, auto engraving resuming, and the standout
feature of auto Z-Axis sinking during cutting, which ensures exceptional precision and performance.
Whether you have a home business or enjoy DIY projects, this machine will meet your
needs without any problem.
The competitive price of $1299 on the Atezr official site makes it even more appealing,
considering that a regular 20W laser engraver would cost a similar amount.
So, it's definitely a major recommendation, especially when you consider its unique features.
Now, let me share a little story with you.
Atezr actually reached out to me about a month ago with an even earlier prototype, which
was still in the early stages of development, as you can see from the unfinished frames.
We spent a whole day testing it in my studio, but there were some functions that they claimed
didn't work properly.
So, I said that I couldn't do a review video until I saw a more refined version.
And you know what?
After just two or three weeks, they came back with a much more polished and refined machine,
with almost everything working perfectly.
I truly appreciate the effort and hard work put into developing this product by the dedicated
team behind it.
I'm always supportive of brands with innovative ideas that actually deliver on their promises.
So, if you're interested in supporting them, you can find the link in the description.
Thank you for watching, I'm Sami, and I'll see you in the next one!
Bye bye!
