NEJE master 2s max with A40640 40w laser modul - Small Laser Module With Big Power

[@snuurtje]

What power setting do you use on the plywood test?

[@Kevo20]

Hi, could you please do a tutorial on this engraving machine? I have no idea what I’m doing, I don’t know how to cut things out or anything.

[@nosaltiesandrooshere7488]

👍 Danke fürs Hochladen! 👍 Thanks for uploading! 👍 Very good and beautiful, thank you! 👍 Sehr gut und schön, danke!

[@kumarthecowboy]

Can you cut 3mm black acrylic in disc shape with 400mm diameter. Please hel

[@rhoadesurf]

Ok but everyone says you can't run it at 100% or you'll burn out the laser?

[@izzo777]

Hi, friend. It works with acrilic? Thank you.

[@זהרברק]

I use neje master 2s plus software laser grbl 5.4.0 Windows 7 The device stops working in the middle of a file. What could be the reason?

[@dekurvajo]

Actually i was thinking, should not be the gantry is the shorter profile? I mean structurally it makes more sense to me using that one rather than the long one

[@oumelkheircha3940]

Is this better or ortur m2 pro

Hello , does it Cut acrylic ?

[@marliprivett4904]

Can the smaller version of this be got with a fixed focus lazes

[@alloysiuswisnu]

Can this module cut acrylic?...what software are you use?

[@duchoang8531]

Do you use double-sided tape to stick the lion on the wall? 3M tape?

[@kukomio]

I sticked the lion to the wall with double sided foam tape amzn.to/3DrA1cR

[@rigohrojas6778]

hola, consulta a cuanta potencia estabas probando la maquina y lo otro a que distancia del modulo a la madera usas ?

[@671JK]

Nice! Is that the actual bed size or you modded that?

[@CrazyManer]

super video, jen tak dál, koukám že už tě i zásobujou věcma na otestování, můžu se jen zeptat, to si pak můžeš nechat nebo to posíláš zpět? :-D díky moc

[@djs7515]

You showed the speed but what was the power setting?

[@kukomio]

throughout the video, the laser power is set to 100 %

[@rc3d490]

Hello, do you make a hole in the chasiss for the air assist?

[@kukomio]

yes, I made a hole in the chassis to blow more air from above on the laser cut line , but it can be mounted at the front instead of the protective plexiglass so that you don't lose your warranty.

[@luisamescua4568]

Will this laser model engrave on a huge board (dinning table) or does the mater being engraved need to fit in the frame of this machine?

[@the_arcanum]

Being an open gantry setting, yes you can move the gantry to engrave wider areas. You'll have to be super carefull aligning the gantry though once it is moved on the next area to engrave. Use tape, mesure distance from edge on every corner and so on... Definitely doable !

[@micro963]

Very nice video thank you for sharing👍👍👍can this cut 1/8” plywood from Home Depot?

[@user-il3sr4ns1w]

Which of the two is better: SCULPFUN S9 90W or neje master 2s plus engraving machine?

[@kukomio]

I haven't tried SCULPFUN S9 90W yet, so I can't answer :)

[@emprentadebaguio]

hi, can this laser engrave on granite?

[@hliasmantzourhs3376]

Hello. Can I buy neje master-2s max 30 watt and then I change the module to A40640?

[@kukomio]

Yes you can, but you need a 12v 4A power supply, or buy a master 2 max with A40640

[@d.abramovsky]

Hello! Good work! Can you tell me, what compressor you use with your laser?

[@Christiantheone]

Let me know if you find out where that blue clip comes from 😂

Also I would like to ask if u tried N40630. This one I have and I cant cut 3mm plywood with 200mm/min 100% power 4 passes :/ . Im using lightburn.

[@kukomio]

V tomto videu kzbin.info/www/bejne/m4vMqJaeaJuJqtk je použitý laserový modul N40630 opticky výkon 7, 5W. Ja používam topoľovú preglejku, ľahšie sa reze, najhoršia na rezanie je breza. Samozrejme, že vždy používam podporu vzduchom a hlavne mať dobre zaostrenú šošovku.4mm preglejku reže pri 250mm/min na 4x (pri 200mm/min by to bolo 3x .iba by boli tmavšie kraje )

[@TheLuKyLuKo]

@@kukomio Ďakujem za odpoveď :) Z čoho máš zložený ten air asist? Viem, že neje predáva takú sadu a k tomu máš nejaký kompresor či ako to je poriešené?

[@dekurvajo]

@@kukomio can you answer in english as well please? It would be helpful to read the answer for his question. Thank you!

[@kukomio]

I used NEJE air assist , you just have to 3d print out the plastic holder(I don't know why they don't put it in the package), I drilled the laser head a little so that the assistant didn't move and the air went straight to the laser cutting point. ​I useelectromagnetic air compressor which is suitable for a laser (Hailea ACO-318 at 60 l / min). It is quiet and does not take up much space.

[@TheLuKyLuKo]

@@kukomio Do you think 35l compressor will be enought? Im asking only becouse I saw that 60l is 60dB and 35l have 55dB if its big difference or no I dont know. Before drilling in head u was testing also normaly? Then it was weak so u choosed to drill it and its better now? Thanks

[@robertomarciano1788]

May I know what kind of plywood you use? Is it 3 or 4mm poplar plywood?

[@kukomio]

I used 4mm poplar plywood

[@robertomarciano1788]

I bought the same 40w laser but I can't cut the 3mm poplar plywood.. the seller told me to focus at 22mm from the engraving sheet at the beginning of the laser module glass. How can I fix it?

[@kukomio]

3:15 You need to find your focus point on the lasers using the inclined plate(my focus point is 15.71 mm). Find the thinnest cut. Don't forget to use air assist for cutting.

[@robertomarciano1788]

@@kukomio At the moment I do not have an air assistance I do not know where to buy it .. My module is 40w as to yours I will try to put 15.71 mm too.

[@robertomarciano1788]

@@kukomio Do you have a telegram contact where you can contact yourself and send some photos for help?

[@frchguy]

Hello, I love your videos. Can I ask you how you make the pin support table, it seems to be very useful for clean cut. Thank you.

[@kukomio]

It's only ceramic tile (400x400mm) and thumb tack push pins amzn.to/3d1ttGa glued with Gorilla super glue gel : amzn.to/2Uslw6v

[@jessicalewisjessielew3399]

@@kukomio I see you also paineted both the ceramic tile and thumb tack pins with some paint. What kind of paint is it?

[@maxwellconniff1189]

@@jessicalewisjessielew3399 It is a good question. I am not sure, it could easily be a particular paint made to withstand high heat. The color of the paint, gives us a hint that it is a particular paint for high-heat but could just be a wise choice by the creator. What I mean is, of all colors(shades) black absorbs the most heat, and could absorb too much heat warping the tacks or fracturing the ceramic tile. White is most reflective and runs the risk of reflecting too much energy to other unintended nearby objects damaging them. So this off-gray is a wise choice. It is also matte paint, so reflections are diffuse and spread out dissipating heat in all directions rather than a glossy paint which would reflect the beam unidirectionally, which would be dangerous. The last main important characteristic of achieving a heat safe paint is that it is open-cell or porous. If not on the can, many paints contain this info on the data sheet on the given company's website. You want it open-cell so that any chemical vapors or humidity cant get trapped in the paint when drying. Because if you have a bubble of microscopic water in a dried paint, then that area gets heated by the laser, the water does not have the free space it needs to expand into a vapor causing bad things. TLDR: 1. Get a paint that is approximately the same color as this one, off-gray and matte 2. Make sure it is open-cell or porous paint. 3. Put it out in the sun for a day (or better an oven you don't use for food) so all vapors can evaporate through its open-cell structure. Now if the laser hits it, it wont be noxious

[@cervezatoledo9634]

Hello, thank you for the video, could you please help me?, i was wondering if once you calibrate the height of the laser, you never move the height for different materials?, for example plywood 3mm is the same height for plywood 12.5 mm?, thank you very much for your answer and your time, thanks!!

[@weilam03]

You have to refocus if you're going from 3mm to 12.5 or anything else besides 3mm

[@GuruVlk]

Hi, Nice showcase. I checked that they have already 50W and 80W model (dual diods) have you also considered these options? Do they really have some benefits compare to this 40W version?

[@kukomio]

Above all, need to look at the optical power, this is important. The optical power of 15w is as far as I know, the highest for a laser diode.

[@GuruVlk]

@@kukomio i understand it now. One thing I dont understand is the adapter you get with this module. Is it 12V 3A ? = max 36w

[@gtsdude1053]

@@GuruVlk Mine is 12V 4A.

[@jacobhn2]

@@GuruVlk 40w is the laser diode max power it can handle so if your power supply is at 12v 3A = 36w yes a bit low but there are also capacitors that help. the laser module runs at full power also only at 10% power settings but in small chunks (pwm) you are probably better off with 80% power and less speed

[@levieux1137]

they confusingly renamed their modules recently and it seems that what they now call "80W" is this one A40640 (that I'm having as well and which is a dual-diode). They must be facing competition on aliexpress where everyone advertises whatever power, just like with batteries advertising fake capacities. But they were the ones starting to cheat like this by advertising power draw instead of optical power...

[@rollandelliott]

wow, what is true optical power 15W? I thought it was actually 10w?

[@dekurvajo]

As far as i know its 2x7,5W optical. There is a 7.5 single diode as well. Its A60430

[@joakimc]

Thanks for the video. What SW are you running? I just got a A40640 and connected to Lightburn I'm not able to cut through anything thicker than 6mm wood. That might be due to poor air support but still feels like a long step from 6 to 18. I can't seem to be able to find any recommended settings for the A40640 in Lightburn anywhere. Thanks

[@kukomio]

I use Lightburn and when cutting the power is at 100%. Firstly, you need to find your focus point ( 3:15 ) on the lasers using the inclined plate (my focus point is 15.71 mm). Find the thinnest cut at different speeds Do not use very hard materials such as birch, beech, oak. Poplar, spruce, pine, balsa are better Don't forget to use air assist for cutting.

[@joakimc]

@@kukomio thanks. I've just ordered an upgrade to my air assist and hopefully that will make a difference

[@xxxscorpio007]

@@kukomio Theoretically, should the focus point be the same as yours on all machines of that type? Or are there differences possible between the same models?
