Hi, I have the same module. Can you tell me what is the Hight from the bottom of the laser( I mean not the red plastic or the frame but the knob) until the end of the aluminum frame. Thank you
Great question @Soul Relaxation Music . I’ve just measured and the base of the focus knob to the base of the red plastic is 22mm... so add this onto the measurements in the video 👍😁😁
Thanks for the video it is indeed one of the easiest ways of checking the focal distance without a Z axis.. May I make a suggestion though ? If you utilise the whole work area width (or length) and make the slope as least as possible you will get a greater definition of your kerf (beam width) . So either look up the specs or do the test you've done then when you know the focal distance is say around 20 mm have the longest slope you can fit in but only have a 10mm difference between top and bottom ie 15mm to 25mm from the lens. If you have the patience you could also actually burn some sort of scale rather than a single line and this will demonstrate the letter/number burning at the difference distances as well as the line and give direct feed back as to where is the sweet spot.
Good idea, this will give me a good indication of the focal range, I have the 40W (15W output) NEJE, but the lens focus screw is inside the module, so not easily adjustable.
@Maker Z a pitty the focus screw is on the inside... not sure if you can remove the front panel to access easier for the adjustment. Good luck with setting up!!
@@NEWTechCreative I believe you can buy adjustable lenses from NEJE from NEJE shop for this purpose. For you just doing engraving I don't think you need it and indeed maybe even the shorter the better for you to get less surface burn but for others more interested in cutting then I agree with most of the comments and the longer the focal point the better. A z axis with a stepper and a TOF laser distance module would be a great addition. Just park the laser over your work piece press a button and perfect focus every time (for engraving). You'd have to type in the thickness of the material so that it could work out the half way point for cutting.
How are you controlling the laser with the cnc? I have an avid cnc and would love the option to add a laser module to it but I dont know how I would get the two working together.
Thanks for your comment @Travis J. I control the laser through lightburn…, however lasers don’t play well with mach3!! I assume you have a mach3 control board, but unfortunately it only supplies on/off not variable control! They only way to use it on a mach3 platform is to deal with the on/off control or install a secondary grbl based control board. Unfortunately I don’t have much knowledge of or how this could work, but will have a play sometime down the track.
hello, could you tell me which control board are you using with this laser? i'm using mach3 but it seems tricky to make the laser work properly without delays :( are you using arduino?
G’day @AKKA ! I’m using an arduino uni with grbl. I have got a Mach3 board that I will upgrade to in the future… but haven’t tested the laser on it yet sorry!!
@@NEWTechCreative could you elaborate? Or point to a video that you used? I'm trying to incorporate this laser onto my AVID cnc which uses Mach4, but I'm having trouble sourcing any info on how to go about it. Any help would be greatly appreciated!
@@ned_mograph5957 thanks for your comment. I'm not familiar with mach4 control boards, however I'm sure this is possible. You will have to look into what type of control board you have already and outputs available to attach the laser PWM signal to. This is usually an output pin and a ground pin. If you are stuggling to find anything in google, your welcome to send me a photo of your control board to newtechcreative@gmail.com
@@ned_mograph5957 I found this link that i think could assist you... warp9td.com/index.php/gettingstarted/setting-up-the-smoothstepper-and-mach4#EssLaserConfig
I did your method is has some merit but. it measured out to 22mm. so I set it at this and got a rectangle laser light. I raised up my laser and watched the rectangle go square and tiny. It ends up being my original setting of 50mm from the aluminum frame.
I'll try it, but the same module (I own one) lost about 50% power after 6 hours of cutting at 85% power, so I don't suggest to use LD for long time cutting, but just for try how powerful is. In my exeperience with Neje module the best way to use it is for engraving, not for cutting.
@giuseppe danieli- I would agree with you here! My main use is to engrave only, however I wouldn’t invest long periods of time to cut timer with the laser as it’s not equatable for time and money.... luckily I have my spindle for rapid cutting!! It’s a shame that yours has not lasted long. I would consider contacting the company where you purchased for replacement as NEJE promote that the lifetime should be 10,000-20,000 hours!! Do you use air assist?
I've just build my first air assist, mostly for smoke and dirt...About the LD the problem is the loss of power, and is normal with pulsed LD, but for engraving is still ok. Now I'll try the 40W model that use two LD and have an optical output of 11÷13 Watt but same dimension of 30W model, thinking about how to drain more heat from the module. I'll keep in touch for next video. Ciao from Arenzano, Liguria west coast, North Italy.
I have a 10w (7.5w output) blue diode laser, having absolutely no idea what I'm doing, I found my focal distance to be 10mm from my material, with the adjustment wheel turned almost all the way to one side. Is this normal? It works for me and my burn line is very crisp would be about 0.5mm wide if not thinner.
Thanks for your message @Tristan Sherriff . I’m not familiar with the 10w version, however sounds like you have dialed in well… unfortunately 10mm is very close compared to my 30w version and might have a short focal area, so cutting thick material will flare out and might not be as precise…. Although your setup will work well for clean/sharp engraving! I suggest doing a few tests before diving into bigger jobs. Thanks Tristan 👍
What power/speed would you recommend to draw the line? With something like 7cm of difference between the left and the right, the lower part doesn't get any engraving at all
Thanks for your comment @J4N . It depends completely on what laser module you are using, however I would try 80mm/s at 95% on a 10cm line. If you have a focus lens on your laser, try adjusting furthest anti clockwise and try as I did in the video… if you are using a fixed focal lens, depending on what one you have it might only be a shallow focus and will drop off if too far away from material. Sorry I can’t give you a definitive solution however it will be trial and error! 👍
Haha! Yes I understand your point… however it was the only side I could reach at the time and if I flipped the calipers the camera wouldn’t see the digital screen! You have a good eye Derek 😆
Hi, very helpful video. Can I ask what is the name of flexible pipe that you use for the air assist? I am looking for that but don't know the name. Thanks before.
Thanks for your message! The one I’m using is called: ‘Mist coolant lubrication spray system’. However I use this with my CNC milling as well. You might be interested in just a flexible air hose if you only need air. 👍👍
@@NEWTechCreative thanks for the response. Yes, I only need air, but I find it is hard to direct the air flow to the exact point where laser make contact with material if just using a flexible air hose. Or at least it is hard to recalibrate everytime I want to adjust the laser head or material thickness for example. Is it just my believe that the air flow direction need to be on the exact contact point between laser and material?
This is a good question @Yudianto Luo ! As I only use the laser for engraving, the sole purpose of my air assist is to redirect smoke away from the laser lens to avoid build up of residue and cool down the burnt surface, so I really don’t require precision with the air flow with engraving. If you require air assist for cutting through material, I would install a 3D printed air assist nozzle… there seems to be a few different versions out there that give more prediction with air flow. I believe the main reason for precision air when cutting through is to stop charging/causing a fire, removing any debris and forcing smoke away from lens! This does impact cutting quality somewhat. Hope that helps!
@@NEWTechCreative Now everything make sense. Yes, I use 3d printer nozzle for air assist, but found it counterproductive with engraving. It created char with same direction with the air flow. But for cutting a material sometimes it decrease the pass needed, but sometimes it won't due to lack of pointing accuracy. Thanks, learn something here.
Thanks for your message @vijay suthar . The suggested cutting parameters for cutting 3mm ply in one pass is 100% at 100mm/min, however I use about 95% power at 100mm/min with sometimes 3passes to cut through. It also depends what type of ply/timber used and glue on the timber with how many passes. I also suggest using air to clear any debris and smoke as it burns. I hope this helps 👍
Thanks @Jer 1967 ! I initially was going to use the z axis to move on a vertical diagonal, however remembered not everyone has a 3rd axis with lasers, so figured why not let the material come to the laser instead🤩 I’m glad you enjoyed the video 😁😁
?? I’m not sure on your question Guvna. This is the standard focus lens on my NEJE. You need to focus this type of lens before use… different to fixed lenses on other modules.
Thanks for your comment @Антон Петров ! I’m using an arduino uno with grbl. There are issues with Mach3 running lasers and would consider using a dual setup with mach3 and grbl if you are considering of adding a laser module. I’m using lightburn software to create gcode and control the laser.
Hi I was wondering if you've tried the long focus lens that they sell for the 30w unit? Also if you could share your results in terms of the fastest engraving you were able to get with this laser? I have the same laser and I'm trying to engrave large canvases and it's taking much longer than I would like. I'm not sure if it's the speeds and power that's the issue. Nice WorkBee setup btw!
Thanks for your comment @Soorena Aslani . No unfortunately I haven’t tried the long focal lens, however it sounds like it would be great to use it on deeper cuts!! I can comfortably engrave at 2500mm/s with my workbee setup, however I try to avoid scanning and filling large areas and try to keep to outlines only as much as possible for larger jobs as it does take some time. Good luck with the journey 😁👍👍
Hi, I try with my laser NEJE 40w, put power on 100%, wood be oak and plywooad, 1 pass, but line is same in every distance. Somebody know what is wrong? Tnx. Ranko
Thanks for your comment! Try less power (50-80% at 3,500mm/min), a steeper ramp or faster pass… the 40w is a powerful unit. Aim for a light burn not a dark burn 🔥 👍👍
@@NEWTechCreative dear you can make some video on how to use lightburn software I think it is very useful all those thees I dint not use lightburn software correctly you can make a video on how to use light burn software correctly it is very useful me pleas do it
Nice video, I am now using this method of focus but with a different laser module. I unfortunately bought one of the NEjE modules and cannot endorse them. My Neje module only lasted 5 hrs under 70 power and it lost over 50 percent of its power. it cannot even burn the surface of paint after making them a video to get it warranted. well I don't have a replacement as they don't want to warranty it. Well i digress, this is about your video and you did a good job of showing your technique. keep up the good work I will be watching.
Thanks for your comment @Darkrider1962 . Sorry to hear you haven’t had good luck with the Module. I’ll keep an eye out for my power levels, however I haven’t had any issues as yet. I would attempt to contact NEJE any way in case there is something they can do. Thanks for watching 😁
@@NEWTechCreative I did contact NEJE. I was given the run around and then when I got all the requirements done. They said "when it dies completely contact them again". This was after giving them a video of the problem. Good luck if you ever try to warranty.
@Iron man I’m using a cheap 12v car air compressor from the local hardware shop. I’m not happy with it as it can only be used for 15mins before needing to cool down. I’m in the process for exploring other options and will post when I’ve found a better option.
Hello, what kind of opening you use with your simple air compressors? I have a decent airflow using an aquarium pump as air compressor and a 3d printer nozzle 0.4mm as tip. the small exit compresses the air to become good enough to serve as air assist on my Ortur LM2.
@NEWTech Creative Hello, I'd love to watch your video once I get my laser cutter to work. You would not happen to know how the interface adapter board of the NEJE 40630 would connect to the Makerbase DLC V2.1 PCB, would you? I can't find the information anywhere snifff.... I connected the yellow and black wire to "laser" on the MKS. Do you know whether this NEJE need an independant power supply or whether this yellow/black wire is the power supply from MKS to NEJE. What flummoxes me most is where I am supposed to plug the Red/Black/Yellow wire connector into MKS DLC, connector which is the most important one, I reckon since it controls the laserhead. Thanks in advance for your reply.
Thanks for your comment @Margery Maraudy . You are correct that your yellow wire needs to be connected to the laser output of the MKS board and red wire to the +12v(positive) out and black to the -12v(ground) out. The only concern is that you have enough power supplied to the mks board to support the motors and laser module… to check, you will need to calculate your motor max output amperage and an extra 3amps for the laser module…. I would be safe to say you need a 12v 10amp power supply to easily power everything through the mks board. If you decide to power the laser module using the red and black wire with an external power supply, you will need to split the back wire both to the -12v(ground) on eternal power supply and -12v(ground) on the mks board output to ensure the yellow wire has a return ground signal. Once all connected, ensure that you have changed your $$ grbl settings to laser control and adjusted your parameters as needed. I hope this helps! Thank you
@@NEWTechCreative Thanks for your reply but I am still at a loss. I selected a 5A power supply and the NEJE is only 30W so 2.5A is required and that leaves 2.5A for the two NEMA and the board which should be plenty enough. My knowledge is very poor (I understand negative/positive and I don't know why negative is also called ground which in electricity is something else, all the other bits of the PCB remain a wonderful mystery lolllll). I still don't get on which port of the MKS board I am supposed to plug in the 3 pin Y/B/R connector. On the NEJE adaptor board it is written: 12V, GRND and TTL and I expected I'd only have to plug into one of the MKS ports...but which one? I can't find any port marked 12V/GND/TTL. Am I supposed to remove the JST connector and connect the 3 wires in different places on the MKS? NB: the eternal supply is, I suppose, the big green thingymebob. I tried connecting the one on the adapter to the one on the MKS respecting polarity but I obtained no result. On the MKS, I have five 3-pin ports: 3 for the endstops, one marked "Extra" and the other "Probe". I think I should stop bothering you and get a reply directly from NEJE if I can on the question of "where the heck do I plug this one and if it does not plug directly why did you put a JST at the end ?" lolllll If I don't I'll keep trying and blow up the PCB as so often lollll. Thank you very much for your kind reply.
@@NEWTechCreative Ah ah..... I reckon the penny has dropped after a littly experiment ! The laser port is for the control of the laser and the 3 mysterious wires ARE the power supply which is exactly the opposite of what I thought. I'll read your instructions carefully and try to apply them. Pray for my MKS DLC lollll
Just to keep you posted: 1) the NEJE 40630 will require an independant power supply as the MKS DLC advises 20W max for the laserhead. 2) the wiring can't be that obvious as NEJE informed me an engineer was working on it and he required a few days (crumbs!) Hope their reply will help others in future.
To my knowledge mach3 doesn't handle laser module very well - it can only output constant signal - not variable signal. I would upgrade to another type of cnc controller if you want a laser module.
Great question @Prisma Arte Laser! To be honest with my laser I really don’t know. I can with the spindle though! If your interested cutting acrylic often, I would suggest investing in a C02 laser…. This would save time and be much cleaner.
@@NEWTechCreative Golden acrylic is like an ordinary mirror. If you have tested the recording on the back of a mirror, I imagine the result will be the same.
Thanks for your comment Rifqi adi prayogi. The hose that I’m am using in this video is called a ‘Mist Coolant Spray System’ and just using a 45w fish tank air pump to pump air through, however I know that there are many attachments available for air assist that are 3D printed, but you will have to do some research! Thanks for your support 😁
Great question! Unfortunately I’m sure sorry as I’m holding off installing my mach3 control board and still using my Arduino Uno grbl. There seems to be many videos on mach 3 lasers, so would suggest checking these out!!
Thanks for your comment @Mendella Carter . I assume your referring to the control board? I’m using an arduino Uno with grbl then connecting to my pc running UGS for milling and lightburn for laser engraving/cutting.
@Mendella Carter I have a kit workbee with a water cooled 2.2kw spindle and 2x 80mm spindle mounts purchased separately. Heavily shielded cables ensure no EMI as they run back to the control box under the Workbee. The table is custom. Feel free to check out my previous videos on the build 😄😄
That’s correct! The name of the laser is NEJE 30W, but in fact it only draws 7.5W with the laser. This is common knowledge with NEJE lasers, however I think this is a good point if I ever do a review video.
Not particularly @Martijn V ... more like saying it’s a 30w module.... module meaning that it supplies 30w to both the fan, components and laser diode.. Module doesn’t refer to the laser diode! Feel free to read more about the NEJE 30w laser module on their official website!
@@NEWTechCreative To be clear, the laser module draws up to 30W from the power supply. The diode delivers up to 7.5W of optical output. It's not unfair advertising; It's just the way diodes are marketed. Even C02 lasers are marketed this way. Buy a 100W C02 and then open the back and read the tube and you'll see it's 80-90W of continuous power.

My Neje module only lasted 5 hrs under 70 power and it lost over 50 percent of its power. it cannot even burn the surface of paint after making them a video to get it warranted. well I don't have a replacement as they don't want to warranty it. Well i digress, this is about your video and you did a good job of showing your technique. keep up the good work I will be watching.
Thanks for your comment @Darkrider1962 . Sorry to hear you haven’t had good luck with the Module. I’ll keep an eye out for my power levels, however I haven’t had any issues as yet. I would attempt to contact NEJE any way in case there is something they can do. Thanks for watching 😁
@@NEWTechCreative I did contact NEJE. I was given the run around and then when I got all the requirements done. They said "when it dies completely contact them again". This was after giving them a video of the problem. Good luck if you ever try to warranty.
what do u use for an air compressor. all compressors i try put out very, very, very, little air.
@Iron man I’m using a cheap 12v car air compressor from the local hardware shop. I’m not happy with it as it can only be used for 15mins before needing to cool down. I’m in the process for exploring other options and will post when I’ve found a better option.
@@NEWTechCreative thx.
Hello, what kind of opening you use with your simple air compressors? I have a decent airflow using an aquarium pump as air compressor and a 3d printer nozzle 0.4mm as tip. the small exit compresses the air to become good enough to serve as air assist on my Ortur LM2.
Thank you very much! This is great!
@NEWTech Creative Hello, I'd love to watch your video once I get my laser cutter to work. You would not happen to know how the interface adapter board of the NEJE 40630 would connect to the Makerbase DLC V2.1 PCB, would you? I can't find the information anywhere snifff.... I connected the yellow and black wire to "laser" on the MKS. Do you know whether this NEJE need an independant power supply or whether this yellow/black wire is the power supply from MKS to NEJE. What flummoxes me most is where I am supposed to plug the Red/Black/Yellow wire connector into MKS DLC, connector which is the most important one, I reckon since it controls the laserhead. Thanks in advance for your reply.
Thanks for your comment @Margery Maraudy . You are correct that your yellow wire needs to be connected to the laser output of the MKS board and red wire to the +12v(positive) out and black to the -12v(ground) out. The only concern is that you have enough power supplied to the mks board to support the motors and laser module… to check, you will need to calculate your motor max output amperage and an extra 3amps for the laser module…. I would be safe to say you need a 12v 10amp power supply to easily power everything through the mks board. If you decide to power the laser module using the red and black wire with an external power supply, you will need to split the back wire both to the -12v(ground) on eternal power supply and -12v(ground) on the mks board output to ensure the yellow wire has a return ground signal. Once all connected, ensure that you have changed your $$ grbl settings to laser control and adjusted your parameters as needed. I hope this helps! Thank you
@@NEWTechCreative Thanks for your reply but I am still at a loss. I selected a 5A power supply and the NEJE is only 30W so 2.5A is required and that leaves 2.5A for the two NEMA and the board which should be plenty enough. My knowledge is very poor (I understand negative/positive and I don't know why negative is also called ground which in electricity is something else, all the other bits of the PCB remain a wonderful mystery lolllll). I still don't get on which port of the MKS board I am supposed to plug in the 3 pin Y/B/R connector. On the NEJE adaptor board it is written: 12V, GRND and TTL and I expected I'd only have to plug into one of the MKS ports...but which one? I can't find any port marked 12V/GND/TTL. Am I supposed to remove the JST connector and connect the 3 wires in different places on the MKS?
NB: the eternal supply is, I suppose, the big green thingymebob. I tried connecting the one on the adapter to the one on the MKS respecting polarity but I obtained no result.
On the MKS, I have five 3-pin ports: 3 for the endstops, one marked "Extra" and the other "Probe".
I think I should stop bothering you and get a reply directly from NEJE if I can on the question of "where the heck do I plug this one and if it does not plug directly why did you put a JST at the end ?" lolllll If I don't I'll keep trying and blow up the PCB as so often lollll. Thank you very much for your kind reply.
@@NEWTechCreative Ah ah..... I reckon the penny has dropped after a littly experiment ! The laser port is for the control of the laser and the 3 mysterious wires ARE the power supply which is exactly the opposite of what I thought. I'll read your instructions carefully and try to apply them. Pray for my MKS DLC lollll
Great to hear @Margery Maraudy ! Let me know how it goes. 👍
Just to keep you posted:
1) the NEJE 40630 will require an independant power supply as the MKS DLC advises 20W max for the laserhead.
2) the wiring can't be that obvious as NEJE informed me an engineer was working on it and he required a few days (crumbs!)
Hope their reply will help others in future.
Hola tengo una cnc router con mach3. como logras que funcione el mudulo con el cnc?
To my knowledge mach3 doesn't handle laser module very well - it can only output constant signal - not variable signal. I would upgrade to another type of cnc controller if you want a laser module.
Thanks for your sharing! 👍
Thanks for the support Comgrow 😁
Helo! Can this machine engrave and cut in golden acrylic?
Great question @Prisma Arte Laser! To be honest with my laser I really don’t know. I can with the spindle though! If your interested cutting acrylic often, I would suggest investing in a C02 laser…. This would save time and be much cleaner.
@@NEWTechCreative Obrigado pela resposta!
@@NEWTechCreative Golden acrylic is like an ordinary mirror. If you have tested the recording on the back of a mirror, I imagine the result will be the same.
@Prisma Arte Laser - The laser might be able to engrave the gold film (will need to test), however will not be able to cut through clear acrylic.
How to make the air assist like that?
Thanks for your comment Rifqi adi prayogi. The hose that I’m am using in this video is called a ‘Mist Coolant Spray System’ and just using a 45w fish tank air pump to pump air through, however I know that there are many attachments available for air assist that are 3D printed, but you will have to do some research! Thanks for your support 😁
Brilliant, thank you.
Hi, i Buy this láser, i can cut mdf with this?
Yes @LIONWAR CHANNEL it can cut mdf! Good luck with the laser journey 👍
@@NEWTechCreative I tried cutting MDF but did not succeed. Looking for settings. Please if you can share it. Thanks in advance
straight to the point...the video not the laser. haha
😂 knee slapper 😂
how to install neje laser modul with mach3 usb?
Great question! Unfortunately I’m sure sorry as I’m holding off installing my mach3 control board and still using my Arduino Uno grbl. There seems to be many videos on mach 3 lasers, so would suggest checking these out!!
its vari focus optimal is 10mm from heatsink
What platform is the cnc on.
Thanks for your comment @Mendella Carter . I assume your referring to the control board? I’m using an arduino Uno with grbl then connecting to my pc running UGS for milling and lightburn for laser engraving/cutting.
@@NEWTechCreative cool thanks for the reply and what is the setup you have for the router is the footprint custom or kit
@Mendella Carter I have a kit workbee with a water cooled 2.2kw spindle and 2x 80mm spindle mounts purchased separately. Heavily shielded cables ensure no EMI as they run back to the control box under the Workbee. The table is custom. Feel free to check out my previous videos on the build 😄😄
Ty, I'll try.
Can you tell us the model number of the laser? Thx.
Thanks for your message! I’m using a NEJE 30W laser ‘new model’ module. Thank you
thats not a 30 watt laser thats for sure might draw 30 watts but wont output 30 watts
That’s correct! The name of the laser is NEJE 30W, but in fact it only draws 7.5W with the laser. This is common knowledge with NEJE lasers, however I think this is a good point if I ever do a review video.
@@NEWTechCreative yea its just like saying my car has 300 horse power and it actualy has 120
Not particularly @Martijn V ... more like saying it’s a 30w module.... module meaning that it supplies 30w to both the fan, components and laser diode.. Module doesn’t refer to the laser diode! Feel free to read more about the NEJE 30w laser module on their official website!
@@NEWTechCreative To be clear, the laser module draws up to 30W from the power supply. The diode delivers up to 7.5W of optical output. It's not unfair advertising; It's just the way diodes are marketed. Even C02 lasers are marketed this way. Buy a 100W C02 and then open the back and read the tube and you'll see it's 80-90W of continuous power.
wow
