Atezr L2 36w Laser | Autofocus, Intelligent Air and Z-Axis control!

The Atezr L2 36w machine is packed with a powerful 36-watt diode laser module, automatic air assist, and an addressable z-axis that gives us autofocus and variable z-axis depth via layer control in Lightburn! We'll test it's cutting ability as well as it's high speed engraving for both detail and power.

[@stevehaynes2857]

Thank you for your efforts making this video. I am about to venture into this kind of machine for my workshop and I am convinced this is the best one to go for based on features v cost.

[@Vintauri]

Glad I could help. It is a nice machine!

[@chucklenz9011]

A lot of info. And well presented.

[@Vintauri]

Thank you, I do my best to cover the bulk of the features and add some real project tests.

[@koomber777]

Easily the best reviews of these diodes on youtube. He actually shows the back of the cuts and what the edges look like. Really helped me dial my expectations for one of these units. Like and a subscribe from me

[@Vintauri]

Well thank you for the kind words. I do try to cover as many aspects and give some realistic expectations of the machines to help better peoples understanding of what to expect over the advertising hype. I appreciate the sub as well!

[@Essentialvideophoto]

Great review. appreciate for taking good amount of time to do this review. Im just waiting for one to arrive, Thank you.

[@Vintauri]

Thank you! And enjoy the new laser!

[@jeffteeter501]

Very nice. I am not looking for a new machine but if I were, you may have convinced me.

[@Vintauri]

Yeah there are some cool new features in this generation of laser. The Z axis options really open up some more flexibility!

[@eddiec1960]

Hi, great video, very detailed. I have recently taken delivery of this machine and I note from the files on the USB stick supplied with it that it has a 'Standard' mode and a 'Fast' mode. Have you done any tests of these modes or know how to use the fast mode? Have you by chance created a Lightburn .clb file for this L2 36W machine? Thanks

[@tiborzavrl]

Hi, interesting and informative review. But isn't this model the same as the iKier K1 Ultra: 36W, only it's painted black. Have you ever tested laser engraving on a 3D model that you previously engrave on a CNC router? Can this laser and also the IKIER adjust the height of the Z-axis controlled via NC code? What is the engraving speed then, because the motor for the Z-axis is much slower. As shown for the model NEJE 4 max.

[@billlatham435]

Very informative video. I think I'm convinced this will be my next laser. I was wondering. When you were demonstrating the power failure/resume feature with the pendant and you were able to set the location at the bottom-left. Would that work when using Lightburn also, or is that a feature only when you've put the file into the controller? That would come in handy when I'm using my honeycomb. Thanks.

[@Vintauri]

The power resume feature only works from the offline controller as far as I know. It would be great to get it working from Lightburn. That being said, if you have a long burn where you might be concerned about a power outage, then you could export the job from lighburn, then run it from the USB port and offline controller.

[@billlatham435]

@@Vintauri I'm sorry, after i reread that I realize I made that confusing. If I'm using Lightburn, can I establish the location of my workpiece like you did with the controller when you picked "bottom left" and start my cut/engrave there? Or is that only possible when you load your program into the controller? Hopefully that makes more sense?

[@r1954eagle]

.What is the wire with connecter end that hangs down next to wifi antenna rightside bottom of the control panel , what does it connect to? I wish there was a way that I could insert a picture... Thank you

[@Vintauri]

I noticed that too and I’m not sure but my guess would be that it’s a port for future accessories.

[@bugsterrx4947]

Hi! Thank you for all you do! I want to ask if you had to buy the honeycomb laserbed separately? If so, what size fits the size of the machine? Oh, and same it goes if I want to buy an enclosure? Thank you very much!

[@Vintauri]

I used a 500x500mm Honeycomb panel that I already had and I was able to just fit it into the large comgrow enclosure. For the panel make sure it's a steel weave and not Aluminum such as this one. amzn.to/46qZYqH Here is the enclosure that I used, but it was a snug fit. amzn.to/46kGBiT If you want something that has a little more room side to side and front to back this one would fit better but wont be as tall if you are looking to add a camera. amzn.to/3PtEYsk

[@ericinthecircle3631]

Great video. I am expecting my L2 36w to arrive today or tomorrow. Any suggestions on general settings to dial in for lightburn? Ive never used lightburn before so not sure on ehat might need adjusting before running the machine.

[@Vintauri]

Lighburn should auto detect your laser when you go to the devices tab. From there you’ll want to follow the manual to set up the autofocus feature. Once you have that going then I would run some material test grids to get a feel for what your laser can do. I have another video that talks about the material tests I recommend watching. Just have some scrap material on hand to play with and get used to your laser! You’ll soon figure out your workflow on using it. Congrats and have fun!

[@ericinthecircle3631]

@@Vintauri thanks for the tips. I have lots of scrap materials to try things out with. I will look for your video on test materials. Look forward to seeing more videos by you.

[@hacklabdesign]

Make sure you use the cable that comes with the machine to connect it to the USB of your machine. Most cables will not recognize your laser. I’m making a review video of the 36 watt L2 today.

[@ericinthecircle3631]

@@hacklabdesign yeah I tried to use a longer cable but it didn't work at first. But I think it was a different problem but by then I had already moved the machine closer to the computer so I'll stick with the original cable. Have you done a focus test? I found my machine seems to be better at 11.25mm over the default 8mm but it had a wide range of good enough.

[@hacklabdesign]

Fantastic video, you’re an amazing teacher. Subbed, I have the same L2 36 W and my Z axis seems to over limit down with error when I select auto focus [ESP500] ?? so basically my auto focus doesn’t work or I don’t know how to use it

[@Vintauri]

Is it pressing into your material and not triggering? Or is it not reaching the material and stopping the autofocus function?

[@hacklabdesign]

@@Vintauri it seems to trying to go over its z limit range , the material does not stop it, the z gantry does. Maybe there’s a setting for Z range

[@hacklabdesign]

@@Vintauri it’s not reaching the material, stopping the autofocus function

[@Vintauri]

@@hacklabdesign you might have your module too high in the carrier. Try moving it down using the two mounting screws on the side to loosen it up and slide it down some more.

[@davidrowe1254]

Have you tried jtech laser on Onefinity if so what are your thoughts. Thinking of going in that direction to save space

[@Vintauri]

I have not tried the Jtech laser or any other on the Onefinity. The speeds of the CNC will be a bit limiting on engraving and with the diode lasers they are small enough to hang on the wall out of the way. I also would not want to keep the laser module on the cnc spindle mount while doing cnc carving as the dust created would be bad for the module over time. It’s still a decent option if you need to save the space and run just one machine but with them separate, you can set up each to do it’s primary job well and run them both at the same time if needed.

[@tracyreinmiller6663]

Hi, hoping you are still checking this feed. I bought the L2-36w unit as a pre order and received it in June. Last week the auto focus stopped working. Looks like from the FB group this is becoming a common problem. Wondering if you have encountered this problem and if yes, were you able to fix it. Customer service is very slow to respond and when they do as of yet, they have no fix for the issue. Not sure if it’s a laser module issue or a mother board issue. Hoping you can shed some light.

[@Vintauri]

I have not been working with the L2-36 much recently, but I have been trying to work with an Ikier Pro Max 24/48 unit which is almost identical. I've had a lot of issues with the autofocus failing to work properly on that one. They just sent me a new unit so I'll be seeing if it works any better. I have seen others talk more about the autofocus being problematic which is unfortunate. It would be really nice if they would fix the code so that it did not loose the x/y homing when the autofocus fails. At least then I could manually focus and keep working.

[@tracyreinmiller6663]

Hi Thank you for the quick response. So you believe this is a coding issue and not a laser module failure? Interesting, hadn't thought of it being a coding issue. If yes, then they could write a fix for the problem with a firmware update perhaps. I was just looking at the Ikier model as a possible replacement. Given your current issues, I think I'll wait to see how your new unit turns out. Do you recommend any one unit that is at least 30 plus watts? I'm okay with manual focus if need be. The auto focus is a nice perk but not a requirement per se. I want to stick with a diode for now and budget is open. I would like a large work area so something that can be extended is helpful too. I appreciate your input and love your videos. I've learned so much watching you, Clack Shack and Louisiana Hobby guy. @@Vintauri

[@jeffteeter501]

I would like to know how long it took to engrave the eagle. I just did one with my 20w and it took 6 hrs at 3000mm/min and 50% power.

[@jeffteeter501]

I would have run it faster but my table is not as secure as I would like. I am going to build a new table and secure it to the wall so that it is very solid.

[@Vintauri]

This one took about 2.5 hours. I think I could speed that up if I did it with a zero angle engrave so it's just moving back and forth in the X axis each pass.

[@paulgreen2863]

Does this unit come with a roller and extension kit.

[@Vintauri]

The roller and or chuck rotary as well as the rail extensions are both extra accessories that you can purchase separately for the laser.

[@iq0099]

I have the SculpFun lasers- I am not impressed with the product design. I had to engrave 500 plaques and the cleaning of the laser head module was a nightmare. I wonder how the cleaning is for this laser. Can you provide a video for the cleaning?

[@Vintauri]

That was actually on my list of things to do on a number of the different modules I have now. I do like the design of this air assist cone that in theory, should help reduce the smoke and debris getting to the lens. I also tend to run at least low pressure air even when engraving just to keep some positive air flow through the nozzle to keep the smoke away from the lens.

[@rogerlikes]

my finger is on the buy button, but it looks like there is a lack of support, I sent an email, tried the chat bot twice, and called the number twice and it says the mailbox is not set up. I really want to buy it during the sale, but I feel like I will get sucked into a bad purchase if I can't reach support if needed. Has anyone reading this hat any Atezr customer support interactions they can tell us about?

[@Vintauri]

I have not had to reach out to support with Atzer so far so I cannot speak to the response time. Hopefully the current delay is just due to China on Lunar New year celebration, but I have heard others talk about delays as well. It's concerning as they have made some nice lasers. But support is critical if you have issues that need to be addressed.

[@rogerlikes]

Thanks for the reply. Still no response to the email, or chat bot. I tried to call the number on the website again this morning just to give them a final chance. The phone just rings then goes to a msg saying the mail box is not set up. After that it just hangs up, so you can't leave a VM. Bummer, I really wanted that unit, especially with the hight control, and auto air assist. Now I am researching the NEJE Max 4 20W it has z control as well. and it has a large expandable bed. Basically it looks like all of them are a gamble. Trying not to jump on the X-tool unit, but from a support standpoint I may. Or make the jump to a co2@@Vintauri

[@Vintauri]

The NEJE lasers are nice but they do require a bit more in assembly and the instructions can be a bit left to interpretation. I really like how Neje did the Z axis as well. @TheClackShack did a video on that unit that you should check out. I'm working with a new xTool S1 40w as well and I'm liking how they do the variable Z axis.

[@whanner]

We bought just about every option for this unit but the extension and hood....Were not very happy so far, one of the X rods were not mounted in its socket and would not fit even with the screw out of the socket, had to be hammered in. The unit was scratched up, when I contacted support they said...oh sorry. We paid $1600 for this unit and it seems to have software issues and it will not autofocus and tech support is useless....I really regret buying this unit.

[@chucklenz9011]

Raise back down? HUMM!

[@emce2pl]

This product work for 1 month and stop. Now im trying get guarantee but service complaining things for 2 months. Im done with atezr i should buy sculpfun ... Never buy ATEZR! Terrible support

[@Vintauri]

That is unfortunate to hear. They were pretty responsive when the P-20 and the L2 series first came out.
