Hellou my friend i have 3d printer with 24v pwm controlled fans. I want to use it for leather engraving and cutting. Should be this laser okay for my purposes? What i have to buy? Thanks Jan
was hoping you can help me with something. I got the EleksMaker® EleksLaser- A3 Pro 2500mW Laser Engraving Machine. And i was wondering if i can replace the laser module with a 40W one? do i just replace the stock power supply with one with more amps? are the wirres from the laser always the same so i just plug in into the controller bord? been looking all over but cant find any videos about upgrading laser module that is not from the same company
I just got the chinese laser you are talking about as a replacement laser head for the sculpfun s9 laser machine I bought before. Now the question: the old laser head has 3 pins while the electric board for the new laser has only two pins. How do I connect them?
one of the 3 pins is PWM or signal(freq)... red is + black or blue is negative or ground doesnt really matter where u stick that one ... i did a resistor 3 step assembly on some chinese laser module for a ender 3 version 1 mod, and i linked pwn to positive through some resistors to get maximum 5v on it at 100% power. and the rest through transistors to get 12v max at 100% my supply has 24v through the pins im using so thats why the need for the transistors to step down the voltage. and negative just sits on minus. but i think can go to ground as well. some people put the PWM cable before a mosfet on ur 3d printer that sends the signal to the fan but i can't see the mosfet on my board is under a sink that is glued so ... what is the point since voltage steps up as i turn the fan on with a regulator. im guessing ur laser module has same wires, PWM Plus and Minus. usually pwn if u look on ur laser module where u stick the cable should be written down on the chip above the laser if has one... if doesn't ... find it you must! PWM has different voltage from + so if u by mistake put 24v or whatever on it bye bye laser module. on my end i do need a AC to DC convertor at some point but i see at 100% power the laser stops cliking... or clicks fast enough that doesnt affect the engraving/cutting. in my case PWM as im using the fan for cooling the 3d parts, and since can be controled by gcode the voltage from + through transistors acts as a FQ modulator... so far 1 day in and works fine i can cut cardboard and nails... got some finger burns. 16w 445nm module here.
Hi there mate jus wonder if you could help me. Iv just ordered 20w neje with interface bored. And I'm trying to get it work on my 3018 cnc with no luck
My Chinese laser module is exactly the same as this one. Would you please tell me how to properly connect it to MKS DLC board? There are TTL pins (ground and signal) and Laser+ / Laser- pins on the board. I suppose the Laser+ / Laser- pins are used as power supply purpose, so I don't need to use them because the laser module comes with an external power supply unit.
I just got the 20W model with the laser PWM tester board and I am a little confused here. I am going to be running this off a GRBL controller that does have a PWM output and when I purchased this it said PWM and TTL. If am reading in the comments correctly, you just need to connect the yellow wire for the PWM signal, but there are two yellow wires. One is on the 4 pin connection on the laser module to the tester board but there is a second yellow wire on a 2 pin connection going to the TTL IN connection. So the question is do I have to use the PWM tester board or can I hook the module directly to my GRBL controller? If I do have to use the tester board, I assume the TTL IN connection is what needs to go back to D11 otherwise I would connect yellow wire on the laser to D11.

Ikr from the begining of the video you can tell the 15w light beam is brighter and even a little bit thicker, don't know if it's because it's closer to the camera though
I don't know, the beam that I created never went outside of my test room, the furthest that I tried was 2m and it light up piece aof wood. Now the module is fixed to my cnc machine and I can't take it out. Only one of the lasers can focus beam further than 2m the other one only short distance.
i see, so you can remove the laser from the cnc but not all focus to burn ,. So what would you look for when deciding what kind of laser would make burns at 10 feet or higher,
just bought two 15 watt laser units but after ur video have a question can you recommend good glasses ? i assume you have got some so were to get them and name / brand please simon bowman on facebook in australia caravan pic is me
Hello, I bought a 20W Neje laser but I need to know how to connect to Arduino, can you send me your email so I'll send you the images please. Thank you
Sorry I'm not shearing my private details, connection is simple, just run pwm signal to yellow wire and make sure that you have a ground connected to arduino as well
I just recently bought a neje 20 laser but the module does not continuous run the fan. For a 1-2 minute burn of 50 percent power, the fan will just run for 5sec upon starting. How much power do you use on your video for your neje?
Neje lasers are made in china so what does the video title mean? how can you compare
Thank you. The Neje actually only outputs 5.5w. 20w is the input wattage.
Hi, that 20w and 15w
Is a input wattage
Specified by manufacturer

Seria Legal se voce fizesse uma comparação entre o 5.5W e o laser 20W, ajudaria bastante. tanks.
Can you please tell me how these lasers cut fabric? Cotton, wool, silk?
Can you please post a link to the chinese one?
I'm not sure if you can even get a diode laser to 20 watts
Apparently the power ratings are power consumption, while the actual output is around 5.5w.
@@Nobody-Nowhere weak
@@Trichromatic7.62x54R Yes, but at the same time.. how can it cut plywood at only 5.5w? I have a 40w co2 and these seem to cut wood of same thickness.
@@Nobody-Nowhere Blue light is better absorbed by wood I guess. But still 5 watt is kind of low for that job.
Could you compare power consumption?

Hi. Is 40w neje laser modul cuts more deep than 30W neje laser modul?

I think the focus of the neje is adjustable

Hi, if I'm not wrong, you need to connect laser directly to your gbrl board, however, I'm not using either gbrl board or test board so is hard to say.
There is pwm support in grbl in version1.1.. I myself use grbl but not for laser it's just router....

How far away can you focus the beam down to a pinpoint?
ditto on information and the Chinese driver board?
lease? lol...
typo correction, 'please'..
Does it last long?
Did you get a report on the actual optical power output?
unfortunately no

Why is the 15 watt one a little bit brighter
It's hard to say witch one is stronger, I think they are pretty equal, but I'm happy to hear different opinions
Sorry I don't know
Ikr from the begining of the video you can tell the 15w light beam is brighter and even a little bit thicker, don't know if it's because it's closer to the camera though
Omg. 5 watts isnt a huge difference until you're cutting something depending on the power
So basically 20w chinese laser vs 15w chinese laser.

NEJE 也是中國做的......
is that input or output wattage?
Input, the most powerful diode laser ever is 7w
is PWM and TTL not the same?
no, PWM is pulse modulation.. TTL is basically ON/OFF.

Those arent enough. Put a solid block or double up your glasses
