Rich I just recently bought the NEJE A40640 to replace my a40630, holly Molly what a difference it cuts like my k40 now. I wanted to thanks I was comfortable make the purchase due to your review.
Wow after watching this I’m tempted to purchase one of these and upgrade my Ortur. But, I’m going to wait to see your reviews on the other lasers before I decide. Thanks again for all you do Rich.
Got My Neje 40640 2days ago, can confirm it's a powerful unit, cuts 3 and 4mm. Poplarplywood easy with just one pass, 3mm. with 420mm/min and 4mm. 350mm/min! Peter//Sweden
@@TheLouisianaHobbyGuy Wow, 18mm.MDF, thats not the easiest to cut through, i tested 7,35mm. pineplywood this morning, worked fine with 6 passes att 280mm. speed,100%.and 19,5 mm. fokal height, very pleased with this tiny but powerful thing! Take care over there, Peter
Thank you for the overview. The result is impressive. I am sure you could get a much better result if you will try to add airflow to the cut. I have a 5.5W diode, adding airflow increased quality, speed, and thickness per 1 pass.
@@TheLouisianaHobbyGuy - i have just ordered both the ortur laser master pro and the neje A40640 laser module. What air assist nozzle do you use on the neje? I have a pump but would like to order a nozzle and adapter for the neje. I enjoyed the video and am stoked that the neje will slide into the ortur adpater...
Once again You did GOOD! MY system is 80w but CO2 and I do not have to go as fast as you do, interesting ... enjoy your new adventure ... the only thing holding you back now is your imagination. Lookin forward to see how it goes. Thanks for Sharing.
Just to be clear, there is no such thing as an 80W diode laser. The maximum any diode laser can be is 7.2W. This laser is two 7.2W lasers compressed by fiber and FAC into one laser beam. The 80W that Neje claims is the power supply, not the optical output. NOTE: IF YOU HAVE A *24V LASER*, YOU MUST USE THE POWER SUPPLY INCLUDED FROM NEJE PLUGGED DIRECTLY INTO THE ADAPTER BOARD! CUT THE RED WIRE COMING FROM YOUR CONTROL BOARD ON THE 3-PIN CABLE!
With this much power and cutting Air assist is a must have. You will not believe how much nicer it gets and cuts more efficient plus your laser module will last longer when all that smoke clogging up the lens. Sure some IPA can clean it but why should it get dirty at all? I took Skulpfun air assist pump and it is not as quiet as they say but works. BTW I have 3 different modules from NEJE and two of their machines. Even with so called 7 Watt (consumption and apparently 2,5 Watt optical power) I am able to engrave anodise visit cards with no issues. That one came with NEJE Master 7Watt machine. In mean time I got upgrade N30820 kit with air assist for that machine and have in mean time modified it so that I can tight up X gantry properly. Measured overall power consumption and with N30820 it is around 20 watt as expected but same machine pulls up to 13 Watt but 10 typically with my program. So I guess that 7 Watt is bit under rated. My so called big one was NEJE 2S Plus with N40630. It is 30 watt consumption single diode. Strongest single diode. In mean time upgraded it with original NEJE Air Assist nozzle (metal one) and with NEJE 3S Plus mainboard. Now it works with newest software and upgrading firmware is way easier. Also does have only one main chip in 32 bit version so it works in 32 bit mode in the NEJE software as well. Anyhow with same file but faster movement it pulls almost same power as the n30820. It is stronger and does more. Maybe more efficient. Anyhow I kinda like what NEJE brings on the table for the money you pay. Sure there are better lasers and one can get 4 diodes laser modules that are more powerful buit at what cost? Costs way more than best NEJE machine.
@@TheLouisianaHobbyGuy I wouldn't know statistics 😀 but yes I guess most people do not have it or just engrave with their lasers and do not really need it. It ain't free either. Good solution costs asuch as half of the actual laser engraver it self. But if you are cutting stuff it is a must have. So many people with stronger laser modules get so happy to be able to cut stuff and do it without the air assist. Than after month or two notice how it can't cut as well is it was cutting. In few videos they even have replaced the module and bashed on cheap Chinese laser modules instead of cleaning the lens or getting new one. Sometimes they use it to long on maximum power and cutting stuff without the air assist that everything inside gets dirty and starts overheating and eventually failing. When there is so much smoke cooling fan will force it true the module and that is a bad scenario. Anyhow I rather have it and do not need it than need it and not having it.
@@TheLouisianaHobbyGuy btw idea fir the video if you haven't done it yet that is. Show the cutting difference with and without the air assist. Sure it was done before but nice video would be good. Difference is stark especially with high power modules. No more burn marks on the top and almost no burn marks on the bottom plus faster. Fir cutting it is a win win situation. Though for the engraving materials like wood it is making a mess. It even fights the logic that in one scenario it makes it cleaner and the other dirty but it is what it is. It us easy to nit turn it on when engraving wood though 😀
Just installed this laser and it is a night and day difference in the one I had. Amazing power! Only problem I have is that it pauses every few minutes and fan kicks in a little faster…maybe getting hot? I’ll get it worked out. Definitely have to burn a power/speed grid to at least get a handle on the difference. Thanks for sharing Rich!
I don't use air assist in my videos because most people with a diode laser don't have it, but yes, I use it the rest of the time when I'm making things.
Think I’m going to try hooking laser up on its own power supply. Still pauses on its own and it is restarting off track ruining my burns. I wouldn’t think running at 40% would get it hot enough to have to shut down, but this is new to me.
@@r.leepanderjr.6308 It shouldn't be shutting down. I run mostly at 90-100% and I never have that issue. Sounds like a module control board issue to me.
@@TheLouisianaHobbyGuy Yes, it is either wrong music too loud or just distracting. Don't get me wrong I love music just not in educational videos. Thank you
Doing the same upgrade. I went on Ali express and got one of those laser tree 40 watt which I have no idea of what the actual output is I guess around 4 watts did not do so good so now the Neje 80 is on its way. Great video . I don't know why these home laser companies just say 3 watt , 4 watt instead they make it bigger than what really it is. Cheer Fred
Good choice! They want to use the biggest number Fred, so they choose the input value instead of the optical output, which is what we're all really concerned with.
This is awesome! Just got my ortur laser master 2 pro. Haven't had the chance yo get it together yet. I ordered the extra head for cutting, but now wish I'd seen this and spent the extra $$$ for this.
@@pepper7144 Excellent laser! Any air assist works well. I like the fact that the Max 3 has an M8 valve so Lightburn can control the on off. It also has a M7, so Lightburn controls my air assist and smoke extraction. I have the M7 wired to a 110V power strip.
@@TheLouisianaHobbyGuy I have heard folks talk about an air pump that is quiet and has a sufficient air flow. Do you have one similar you could suggest? Also does the NEJE have a rotation adaptor? I did not see one on their site.
I have that laser and I do all the cuts at 100% power, just higher speed. It cuts well, but now the concept of cutting at lower power for cleaner cuts looks interesting. It is impossible to cut wood at speed below 60 - it starts burning inside even with air assist. At speed 60 this laser can cut pine 11 mm deep in one pass. Bamboo is very, very hard to cut - much harder than a plywood.
Always using 100% will kill your laser module. Basically burns it out sooner. Which means you will have to buy a new one much sooner than if you use it at 75% to 80%.
what wood is the 2mm plywood? You can't just say plywood because if is poplar it will cut at less power and high speed and if if birch plywood it will cut harder. You should specify in the videos exactly the type of ply wood because people can make high hopes and when they cut at home they won't be able to do it at your settings, because they have harder wood. If you don't know the wood type just say harder essence or soft one.
Doesn't really matter because *my* settings will be *different than yours* , even with the same laser module. I'm not recommending settings, and I never do, just showing examples of what *my settings* were. FYI it was 2mm white ply.
@12:08 Step your focal depth down by about half of the board thickness for a second pass. The beam's cone loses its focus over distance; so as material is ablated, the lower depths are exposed to increasingly less focused optical energy. Strategically lowering your focal height for subsequent passes will overcome that issue, as well as offer straighter cuts.
@@TheLouisianaHobbyGuy Eh, my bad. I didn't consider that before injecting my "know-it-all" comment here, lol! Many thanks for the demo on this module, though! I'm currently exploring ways to get more optical power at a discount, and didn't realize there was a module rated at 20w out. Back when I bought my 7w, it was the highest power I could find at the time without going to gas or fiber.
@@TheLouisianaHobbyGuy Unrelated question: I see you're based out of NOLA. I'm just "up the road" a bit here, southwest of Jackson... Are there any decent stores in your area, who stock CNC and 3D print supplies? There's nothing in my area. I have to gamble everything from Amazon.
Funny I just saw that last night as I ordered a 30W. I was somewhat skeptical of the 80W but now I have to save up for it. Still cheaper than a C02 laser maybe not as good but a lot easier to get started with. Thanks for the video!
Nice! And no, not as good as a C02, but is it? I've been playing with it all day today and it can do everything my old 40W C02 did, just a bit slower... not much.
According to your link, and also in the official NEJE store on ALIEXPRESS, this laser comes with an output power of 10 watts. They don’t have another model that is more powerful now! Which is quite plausible, since put two diodes of 7.5 watts and nothing changes cooling will not work! So 15 watts is pure marketing from the Chinese!
@@TheLouisianaHobbyGuy Dear friend, thank you for your answer! I want to take a 10 watt module from NEJE and put it on my ORTUR 2 PRO. But I have a 24V power supply, and this confuses me! How can I connect this module in this case?And will the NEJE module work fully in ORTUR 2 PRO with 24v power supply?
Agreed Michael! Unfortunately, the only machine I have with AA is in storage while my shop is being remodeled. I am printing one for this machine right now though! 👍
@@TheLouisianaHobbyGuy When you design and print your AA adapter for the new NEJ Laser module for the Ortur will you make that available to download? I don't have a 3d printer but I paid a guy to print my current AA adapter that I downloaded. :)
@@IIIofV Thanks! Depending on what gantry ou have, you may have to use a 2mm spacer. I simply cut them out of 2mm wood. Oh, and you do have to move the Y limit switch up a few mms.
What is the highest power diode laser? The most powerful laser diode we can get on the market is the 6W laser diode from Nichia, which can lase sustainably at 6W. The palm-sized PLH3D-15W laser module utilizes and combines three Nichia laser diodes to reach a real 15 W of optical power, making it become the first of its kind in the world.May 31, 2021
Actually, Atomstack developed the quad-diode module last year and just launched the 20W version this month. x-Tool has followed with their own version.
Hello Rich, with the Ortur LM2, I used your library cut for the acrylic 3mm and you are right, I could not cut through with 7 attempts, the last with 7 passes,, did not cut, so I stopped. You mentioned 9-14 passes, wow.
It's marketing hype from the company. I made that clear in the pinned comment. There is no such thing as an 80W diode laser. The companies have a poor way of describing them. They rate the input and optical output of the laser, concentrating on the input. So the power supply draws up to 80W of current from the wall outlet, however the optical output is only 10W. The most powerful diode laser on the market is the brand new 20W quad-diode developed by Atomstack and followed by xTool, 4 5W diodes collimated into one beam.
having an air assist makes all the difference. Cuts my cut time in half and its better to have a higher travel speed with air assist to keep from burning.
Thanks for this very informative video. I too, have the LM2 and have been spending a ton of time watching videos on CO2 lasers and Fiber lasers. But as a hobbyist, the price tag for upgrading to CO2 or Fiber is a little above my pay grade. I've had my LM2 for a year now and haven't been completely happy with the results I get engraving tile and acrylic. So this upgrade could save me thousands of dollars!!!! This just might prevent me from biting the bullet and purchasing a Fiber laser!! I know each type of laser has it's purpose and everyone has their preferences, but have you already made a video comparing the pros and cons of each of the different types?? Diodes vs CO2 vs Fiber. Keep up the great content!
No, and I don't plan on that Bryan, because there really isn't a way to compare them. It's like trying to show the differences between a Rolls Royce, a Ferrari and a Yugo 🤪
@@TheLouisianaHobbyGuy Thanks for taking your time to answering my question. So I have another for you if you don't mind. I did go ahead and purchased the NEJE A40640 and it arrived last week, so this past weekend I removed my Ortur LM2 20w and cleaned and tightend all the belts and made sure all was ready for the new module. From your video, you were able to mount the new NEJE right to the Ortur mount using the provided mounting hardware that came with the NEJE. The mount I received looks identical to the one in the video, but the mounting holes do not match. I am only able to line up one hole between the two mounts. So my question is, do you know where I can find the correct bracket or do you know of anyone that offers a 3d printed version?? I do not have a 3d printer, nor do I know anyone that could make one for me. I did mount the NEJE using only one screw, but this is only temporary to test the unit. I do not want to run the laser with only one screw. Thanks for any assistance.
any way you could send me the link for amazon for the up grade kit. I tried to look but the A40640 on amazon is 414.00 and states 10 watts?. I have a 10 watt ORTUR. thanks for the help.
Would be interesting to see if you could combine several of these through a similar fashion to get even higher outputs; i.e. take a K40 and replace the giant tube with multiple units like this (and mirrors of course) to create a solid state cutting laser.
The diode dual beam is using the FAC lenses. They are collimating the light and the mirror is joining the two into one beam. So yeah, it is possible to add additional diodes, but the mirror calibration would be problematic. It's not like a C02 where you're bouncing one laser beam over three mirrors. You would never get more than one 450nm beam to travel via three mirrors over that distance. Diode lasers have large divergence angle in the fast-axis direction, so the output cannot be efficiently used unless collimated over a short distance. The radiation angle can only be collimated into a small beam over very short distances. Though I do see the future of diode modules incorporating three or four diodes to rival the C02 at a much lesser cost. The bottom line is profit. The Chinese manufacturers are looking at the market. A $300 diode laser will outsell a $900 diode laser by 50 fold, making it more profitable. But there is a mid-level market they're not seeing. C02 lasers hover in the $2K range and above unless you want a K40. There is a huge $1K market they're missing IMO....
There are modules on the market combining 4 laser diodes abd achieving real 20 Watt power output. They cost nice chunk of money though. They are very powerful and can do more than other diode modules. Still they are limited by the wave length and still can't do transparent materials. For some materials you really need CO2 or fiber or other type of lasers. I am though fascinated with power of today's diode lasers and their efficiency. Someone looking at the numbers like 30 Watt consumption and 5 to 7 Watt output of the laser module would call it not efficient. But knowing that some other type of lasers would need like 200 Watt power consumption plus 50 Watt for it's cooling to achieve few Watt's output power makes thus little diode lasers very efficient.
I noticed that you don't have a diode lazer cleaning video! how to properly clean a lazer lens, my lazer gets dirty very fast! i can only run 2 10X14 tiles then i have to clean my lazer, i know the proper way to clean the lens but most people don't, a scratch on the lens will cause beam diffraction which will scatter the beam and ruin your prints and diminish lazer life.
I have watched you video several times . I just purchased a used Ortur LM2 and have been up making some upgrades. I see you have installed this module on your LM2 is there any changes that need to be done to install the module or is it plug and play. Any stop adjustment? Great video by the way. you are virtually the ONLY video of its kind on the net.
i am totaly lost. i have the ortue master 2 (not the pro), just received my Neje A40640. do you have a detailed instructions. i can't see how to put it all together. the picture at 4:49 confuses me how it attached. are you able to help me?
All I did at 4:49 was screw the Neje mount to the Ortur. I only used one screw, made it really tight and it held just fine for 2 months until I printed a new gantry mount for the Neje.
hi, first i want thank you for all the things that you do, i have a little problem i bought a neje a40640 but it seems doesn't fit with olm2 pro s2 can help me ? thanks in advance
This is my go-to laser when I have a lot of cutting to do on thin wood and I don't want to use the Co2. Although the Atomstack I just reviewed did just as good of a job!
Neje has a terrible communication and support. They owe big time, just as i do! thank you! Is there any chance you can tell based on this test what a N40630 could do?
Hi. If I want to get in to laser cutting ply, which is for marine use case. What do you think is a decent beginner printer on AliExpress today for a good price? I guess I need 80w or even more since it's for cutting 8mm wood. Anything you would recommend or think looks good for a decent price?
80W is the electric power of the machine. 10W is the true optical output. This is an older video, and thankfully they have stopped rating them that way. Diode lasers wouldn't be the choice for cutting marine grade plywood.
What is your opinion on the NEJE 3MAX package with the A40640 already included. I want to personalize cutting boards and noodle boards so need the increased real-estate for larger form factors than the Ortur LM2 Pro.
Hi, I wonder if you could assist me in mounting the Neje40640 onto the LM2(20W LU1-4) laser mount. I have watched the video but I don't see how the 2 mounts can be attached to each other. The laser module came with a med size cross-point screw & small Alice screw but only 1 hole on the laser mount plate that came with the laser will match up with 1 of the 4 holes in the Ortur slider.
One of the things I find frustrating is the fact these manufacturers use total input power instead of output power which is the real data needed to help decide capability.
@@TheLouisianaHobbyGuy I guess I understand the concept but I just mean I need something the equivalent to 5x as strong as my xtool 20 for engraving silver. Which I thought it would do.
When you say 40W, that is the machine + laser power. Diode lasers only come in up to 20W of optical output, which is the new quad-diode modules from Atomstack & x-Tool. Most others are either 3W, 4W, 5W or 10W of optical power. When you say 15W, I'm guessing it's 4-4.5W optical power. Upgrading to a 10W would probably make you very happy.
Do you power the integrated card that comes with the neje module with the power supply of the neje kit?. the explanation of the connection of cables was very fast, you spent more time on simpler things, ... I think
Does anyone know if all the Diode lasers are interchangeable? I have a Sculpfun machine and I want to know if I can upgrade to any laser or if it needs to be one from Sculpfun.
Could you give me some information on upgrading ortur master pro 2 plus laser? I have a 5 watt lase, what do I need to upgrade to 80 watt? I just ran across your channel. I love your explanations. I am brand new to laser engraving.
As I explained in my pinned comment, it's marketing hype. Fortunately companies have moved away from hyping their advertising since this video. They used to advertise the input power instead of the output.
Evening Rich. I have been running a 20 watt laser/10 watt out on my laser since assembly. I have recently upgraded from the 20 watt to the 40 watt/20 watt out laser. I am not getting the results that I expected, as in faster rate to cut 3mm basswood. I am using the exact same settings for the 20 and 40 to cut 3mm, that being 140mm/m @ 90%. Is there something that needs to be changed so Lightburn knows I have a higher output laser? Thanks in advance.
I see you have the same bed system as I have :) I do however have a bit more spacing I am using the other 80watt module with the dual fans. i cuts like a charm
Thank you for answering my previous questions. I have an ORTUR Laser Master 2 and I want to upgrade to the 40640 80 Watt laser module. First, will it fit my machine, and is it as easy as you show on your video? Finally thank you very much for all your videos. I am a pensioner so I will donate $10.00 to you, I wish it could be more but living on a pension means saving for anything I buy for my hobby.
Hi Roger, thanks so much! But yes, it is as easy as in the video. I didn't leave anything out! The only glitch that I'm about to fix is the laser can't home because it hits the frame. It's not a big deal, I just raise it up before I home it, and every new job needs to be focused anyway. But I'm going to design a new mount to print to avoid this.
TheLouisianaHobbyGuy, hi I watched your video on the upgrade to an 80 Watt laser ( I’ve actually watched and subscribed to several of your videos). I have bought an 80 Watt twin laser head it’s not the same brand as yours in the video, mine is a LaserTree brand but is probable the same Chinese manufacturer I followed all your directions to the letter but, it will not cut through a 3.25mm piece of plywood, I have tried everything and it’s driving me nuts. Do you have any suggestions please. Roy
Really great videos. I'm living on your page to learn as much as I can before I buy one. Are you using the new 80w for everything then?? The 20w you got with the machine in collectng dust? Thank you!
Thank you William! I got the one with the PWM wave pulse generator because I'm planning something with that for the future. But all you need is the laser and the adapter board.
Hello from Philippines. I jsut want to ask if I can upgrade the laser module of sculpfun s9? will there be other modifications on the controller? thank you and more power and videos
You have to use the supplied 40W power adapter plugged into the adapter board Reinhard. And you have to cut the red wire on the supplied cable so power doesn't come from the control board.
I got the neje A40640 but when I tried to upgrade the ortur 2 20 watt it dosn't hook up like the video. The ortur is a 3 prong and the neje is a 4 prong. not sure what to do.
@@TheLouisianaHobbyGuy I got and adapter board but the neje A40460 hooks up with a 4 prong connector , the wires that came with the laser master 2 come with 3 prongs. is there a piggy back plug to hook 4 pong to laser and 3 prong to original wiring. I thought I had the same setup as the one you had on your vidio.
Interesting tests. I was wondering if you could answer a question. I am fairly new to laser engravers, but I was wondering why the focus on this laser module is so high at 20mm, but the laser I have is almost touching the wood at about 5mm.
@@TheLouisianaHobbyGuy Does a longer focal lens allow deeper cuts? I am assuming the cheaper lasers come with a short focal lens? What is a F.A.C. lens? What is the benefit over a standard lens?
The LF lens does cut better than the SF. The FAC lens is Fast Access Collimating. Meaning is collimates two beams into one at the proper focal point _(FA)_ and it is more expensive.
Hey Rich, just a quick suggestion/question. Does it matter what the input watage or the output? I would think it doesn't matter what the input wattage but only the output wattage and the % power you are using. Is that a correct assumption on my part?
Yes Sir! Input is sales & marketing hype. Optical output is what matters. I can get a power supply rated for 400W to power a 5.5W diode at 12V. It's still only 5.5W....
So great video that I actually got it too :) Now waiting to see you do more testing. Maybe you could do the same tests you did before the upgrade with your files and then compare them?
It would be too complicated and custom parts would be needed. Comgrow has a 20W output laser that is twice the power of this one. That's the way I would go.
@@TheLouisianaHobbyGuy yes agreed. That comgrow 20 watt is so expensive though for just the module and then you gotta play with the limit stops to make it work correctly. I'll think about it though, thx Rich
Hi, I was looking for the 80 watts laser modul, but I found only the Neje A40640 with only 40 watt and 10 watts output in the Neje shop online. where can i find the 80 watts version?
I am not sure what 12v power supply that Neje supplied? Or your original? Mine is 24v. Also noticed that the link is to Amazon. Not Aliexpress. And I don't think a power supply is provided by either.
I got my from Aliexpress from the Neje Direct store and it came with a PS. The package contents list on Aliexpress says, "12V4A UL Certified Power Adapter". But you're right, it doesn't say that on Amazon, so I guess they have different packages Walt.
I connected the Neje's laser module N30820 to ortur laser master 2 S2 and upon turning on the laser through laser grbl software, the fan turns for 1 second and stopped immediately and little bit smoke came from inside the laser so I immediately turned the power off and disconnected all the cables and haven't turned on the laser since then. Is my laser module okay ? Or is it dead ? I'm too afraid to plug it and check!
