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

[@TheLouisianaHobbyGuy]

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.

[@NINEWALKING]

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 have the air assist, I just didn't use it in this video because most people don't. Thanks for the detailed comments!

[@NINEWALKING]

@@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.

[@NINEWALKING]

@@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 😀

[@FromBeaverton]

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.

[@TheLouisianaHobbyGuy]

Thanks for the tips! After some experience with this module, I do all my cuts between 120-240 speed.

[@zero00044]

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%.

[@georgechambers3197]

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!

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 deep cuts having air assist to clear out the ash is a big help, otherwise the insulating ash just shields the unburned area from getting cut.

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!

@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.

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.

@@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.

[@SoulRelaxationMusic]

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.

[@TheLouisianaHobbyGuy]

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.

[@TheLouisianaHobbyGuy]

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....

[@NINEWALKING]

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.

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

[@TheLouisianaHobbyGuy]

I don't know, that would be a question for Sculpfun.

[@DCDLaserCNC]

I am confused. The link takes you to a 10 watt module. Why does the video say 80 watts?

[@TheLouisianaHobbyGuy]

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.

[@pepper7144]

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.

I'm doing a review on the Max3 A40640 right now. IMO, it's the best 10W laser on the market.

[@zk_6312]

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]

Because this has a different lens. There are long and short focus lenses.

[@zk_6312]

@@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?

[@TheLouisianaHobbyGuy]

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.

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.

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.

[@TheLouisianaHobbyGuy]

No, there isn't, but you may be having a focus issue.

[@Miketoo]

Very good video! I have an existing CNC machine that I'm looking at putting a Laser on. Diode laser looks to be the easiest way to start, I'm not sure if I could mount a CO2 on the gantry anyway. My question is about expected lifetime of the Diode Laser, what can I expect if I cut with it a lot. I would be cutting mostly 6 mm Baltic birch after doing engraving on the surface. I would rig up air assist and would also provide extra cooling to the Diode Laser module if possible. My cutting table is 5' X 5' and I have 18" of travel in Z so plenty of room to install anything. Appreciate your KZbin channel, you provide a lot of good information to people like me that know nothing about Lasers.

[@TheLouisianaHobbyGuy]

Hi Mike, you have pretty high expectations for a diode laser! Cutting 6mm ply in a production setting would be a very slow and arduous task for a diode. Think 100 mm/min and 4 passes min even with the most powerful diode. A better choice for this task is the C02. Expected lifetime is different for different manufacturers, but the better ones are 8-10,000 hours. I have 2 machines in production service for about 3 years now, and neither have shown any signs of degradation yet.

[@Miketoo]

@@TheLouisianaHobbyGuy Thank you for the reply, I’ll look into the CO2 options. Time is money and I can’t tie a machine up cutting that slow.

[@TalkingGIJoe]

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.

Hi Douglass. Almost all lasers are compatible with rotaries. I have seen folks use both the Atomstack & Ortur rotary on the Neje. Neje does sometimes offer a pen roller but it's almost always sold out. Rotaries are just a replacement of the Y-Axis. You unplug the Y and plug it into the roller.

Shouldnt you connect a separate external 12V Supply to the Neje Board and not only the 12V which your Controller can deliver? The Neje can take over 40W electrical power which normally a controller cannot deliver?

Yes, you probably should or it can overheat if used for too long. I bought the kit with the PS & adapter board. Mine came with a 60W 12V PS so I just use that to the Ortur.

[@Marco-zn7nd]

sorry but for the price of the new laser you can get a k40 with a little difference ! a CO2 laser of 40w it's a game changer...

[@TheLouisianaHobbyGuy]

That's right, but the K40 only has an 8x12" bed, so you're very limited on the size of your workpiece. Not only that, but you also can't run Lightburn on it without replacing the control board, which is also a major $$ upgrade. Those two differences are major IMO.

[@erniedilley5709]

Can a 15 watt be upgraded to 40 watts without major changes?

[@TheLouisianaHobbyGuy]

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.
