NEJE Max 4 20W laser engraver: extendable to 750x1030mm, motorized Z-axis, multiple passes step-down

[@chrisduty2886]

On setting focal length, I use the Tool holder. It is 50 mm. Place material, jog laser,lower the Z by 1 mm, place the tool holder on material and lower the laser in to contact by loosening the screws, raise up 1 mm to remove holder. Then lower Z to 26 mm for engraving.

[@FlyBy2507]

Finaly! A laser graver with motorized Z axis 👍

[@USMiner]

Thanks, concise and to the point. This is the 2nd time I've run into your channel looking for laser engraver reviews and yours are the best.

[@Reindeer-ry2lf]

Interesting for a huge work area. It seems like it was Frankenstein build but you as professional make it look like a piece of cake to use. Thanks again for the sleuthing and professional videos 📶💪🇺🇸😎

[@kickpublishing]

I found this invaluable in helping me get my z axis setup sorted, thank you

[@Tdog500]

Thanks for the review. I takes a lot of time putting something like this together, great job!

[@jerrodmcdaniel2043]

Great review as always. Thank you for all you do to help us to succeed in our everyday task Looking forward to more great reviews from your channel

[@MrDaneis]

I barley have room for a few P1P's... I'd have to get rid of my car to own this thing. Amazing review as always!

[@snapshooter65]

Good review and a nice taste of background jazz music!

[@chrisduty2886]

Hello, I would like to extend this larger than the optional extension kit. Unable to find the extrusions used in this machine. Could you point me in the right direction?

[@KatherineSandersis]

Always enjoy your videos, and this one gives us a larger view of the machine.Great vid👍

[@KnotHead1008]

The Bluetooth compatibility is the issue over both win 10 and 11. Most of these builders may have experience with the hardware build, but not with wireless 🛜 hardware. I also find that didn’t provide a cover to block the intense light. Please could do a review of the plotter? Video was 👍👍👍

[@aberodriguez4149]

Very impressive review as always, thanks for such detail reviews.

[@atienne_navarre]

You are correct. NEJE is HORRIBLE at documentation. I bought the MAX3 and information on how to focus the laser head is all over the place. They even have in house videos on here that contradict each other. I probably wouldn't buy another laser from them because of this. The hardware is pretty good ONCE you learn how to use it which is a lot of hit or miss and searching. Im probably going to replace the variable laser head on the MAX3 with something else even though Ive hardly used it. I mainly bought it for the size anyway.

[@KatherineSandersis]

There are always various ways to focus. It's just that people offer more quality methods than their official ones. I like open design. A fixed approach will make it easier for the user, however an open design will make your creation more remarkable. 😉

@AURORA TECH Uma coisa que tambeim notei e que o laser fica ligao mesmo com a opção de 0% potencia isso e normal?

[@luizaugusto9643]

Oí amigo necesito de uma ajuda eu comprei uma máquina dessa neje max4 e80 com essa extenção de área de 1030mm e 750mm ontem eu a estalei en lightburn coloquei o tamanho da área de trabalho de 1030 - 750 más en lightburn a direção do láser sai fora da área de trabalho e me choca nas estruturas da máquina poderia me ajudar? Obrigado

[@olafb.2929]

A good review, as usual. Thanks :)😊

[@stvcolwill]

awesome review. Instantly subbed! great job!

[@jeffallen3382]

Were you ever able to find a fix for the Bluetooth problems?

[@willyblain189]

Hello , thx for your video 👍🏼very useful , Can you tell me the height of your printed block for the rotary feature ? Thank you

[@AuroraTech]

It actually depends on the size of the object you need to engrave, the blocks I printed are 50x50x120mm.

[@kickpublishing]

How did you set the laser height for material tests in lightburn?

[@PredragKnezevic-wu4om]

Kako i gde ga kupiti?Divan je.Cena?Bravooo❤

[@nevilenobody606]

That exposed laser lol. BTW have you considered doing a test of the available good quality laser glasses other than those supplied by the machine makers?

[@milancapik2399]

Hello, I have a question. What is the accuracy of cutting a circle? I had one model from Atomstack, and there the cutting accuracy fluctuated around the circumference by 0.4 mm. It didn't make me an even circle, but rather an uneven ellipse. I want to buy NEJE MAX for the size of the structure, but I am afraid that this problem will get worse. So far, I haven't had a laser other than Atomstack. It cuts the rectangle/square exactly to 0.02mm, but it can't handle the circle. That's why I'm interested in how it is with NEJE, since it has a completely different construction. well thank you

[@eherrmann01]

Thank you so much for this video. I've been considering a laser engraver but most of the videos that I've found are glorified sales pitches, without much useful information. One of the main uses that I have for one is engraving on hand-turned wood pens. Would I need the rotary roller to engrave on pens that are ~ 15-18mm in diameter?

[@peterfabry9687]

I'm considering of bying a Max 4 E80 but in the KZbin video's they have a tankchane on the X and then in other video's they dont....even at the site they show a tank chane.

[@peterfabry9687]

Why?????

[@bartv6387]

Where can i get the brackets for the honeycom bed? Now its a crime working with the MAX4

[@arranp1693]

How do you configure the lazer to recognize the extension kit? I got one a little while ago but can't figure it out!

[@federicowilckensclaussen]

hi change the 131 value on light burn, just write $131=1030 cheers!

[@luizaugusto9643]

​@@federicowilckensclaussen obrigada amigo me salvou estava a 4 días varias horas por día e não consiguia alterar gracias a você deu serto! Que Deus te abençõe muito

[@alandimery3379]

A great video, thanks. I am interested in purchasing a 20w laser engraver. I am concerned about the noise of these high powered diode lasers. I have heard that the Neje is quieter than most. You never mentioned this but do you think that this is so? Thanks

[@user-ly1iq5di3g]

Does anyone know if the stepper drivers on the control board for this are silent (TMC, etc.)? I've gotten spoiled by them on everything else...

[@vinnnocc]

STL for the 3d printed brackets?

[@doctorpd1959]

Would you be able to provide the Lightburn grid test files for engraving/cutting (in Lightburn extension .lbrn2) for download please? Thank you.

[@avejst]

20W laser and a Open frame is not a combo I would recommend!

[@CrisAnderson27]

Loving your reviews. Out of all of the lasers/brands you've reviewed so far, which is your preference? I'm really thinking of going with the Neje. I already have the 3s Max with the A40640...but I'm really wanting to take advantage of the improved power and speed of the new unit.

[@CrisAnderson27]

I bought the NEJE, and the power supply quit within 48hrs lol. The laser itself though is excellent, cutting construction grade 4.5mm luan plywood at 500mm/m-100% one pass. In addition...realignment has been incredible. I can home the machine and restart it at the exact position I choose. The stepper motors stay locked, meaning they don't relax like other machines (or NEJE's old machines), which is what causes poor alignment. In addition homing zeroes the machine to .001mm accuracy per NEJE. So far, I'm inclined to believe them as this was one thing I've tested purposely. Also, I believe the reason that NEJE rates it at 20,000hrs is their much improved cooling system. 100% cooper heat sink and excellent air flow is top of the line.

[@jppalm3944]

No where on the site doesn't mention watts. What is 80 module?

[@MarcusBuer]

This is an issue with almost all diode laser engraver brands. They try to use in marketing materials and product naming how many watts the machine uses instead of optical power, to make the customer think the machine is more powerful than it actually is. This machine has an optical power of 20 watts, probably using four 5w diodes.

[@JoseHernandez-mj6ne]

Great review. Can you tell me what’s the best laser engraver and cutter with 60 watts or greater for beginner as a never owned one. Easy to set up and use?

[@AuroraTech]

A desktop diode laser cannot generate as much power. You might want to consider the xTool P2, a 55W CO2 laser: kzbin.info/www/bejne/sGq2eIulpt5shJI.

[@JoseHernandez-mj6ne]

@@AuroraTech thank you. As always I enjoyed your reviews. You are a smart cookie young lady. I see great thing in your future. That’s coming from a Jar head.

[@Piccyman1]

Why are the laser cutters so expensive, there isn’t much on them justifying $1000

[@jparniawski]

Hype and popularity. Same happened to 3d printers.

[@miuix4795]

Never neje again ... No service and real criminals
