Nice, I'm going to print this except for the laser holder. Thanks!
U R THE BEST 🤗♥️♥️♥️🥰
great project and a nice video editing
Wow, the video editing is amazing, I really enjoyed every single minute
keep going bro 😊
This looks wonderful, thank you for the high quality guide!
Thank you very much, do you have any suggestions for the next video?
@@Kady3DPrinting I’m not sure, perhaps a simple PWM circuit, not with a 555? But whatever you want to make, you have excellent taste!
@@Kady3DPrinting can you sand code for arduino?
A laser of that power can cause instant damage your eyes, even looking at the spot that is burning can cause retinal damage. Reflections off a bright surface still have enough power to cause permanent eye damage.
Code de bhaii
Why do you use 250mW laswer, i see they use 500mW . What’s the difference between these, and the 250mW is enough for engraving wood?
Also, you don’t use the heatsink for the laser? Is it necessary? Thanks in advance
@@tamaica7770 i hope to get one, it's not available at my country

Great!!! Thank you very much!!!!
nice project. you also could use a transistor or mosfet instead of the relay, it gives you the option to dim the brightness of your laser so you can make different gradients..
i will be taking this approach for mine :D thanks!
Very nice idea, It will be more advanced and great
Hey. Do we need the heat sink for that laser? Will it be enough for engraving on metal sheet?
Great job.
good job bro
Awesome man!
Thank you, any video you need we can make it for you
hi! great video! i have one qustion for yuou, since i don't have old DVD readers i'm going to buy the motors and shafts on internet, can you please say me the diameter and the lenght of rails?
Thanks for sharing
Project so nice and simple that it's a shame not to do it.
Nice video! One question, in which pin of the shield do you connect the short red cable from the relay? The one that goes to the 5v input of the relay. Is not clear in the video, but it seems that you connect it to the 3.3v of the shield, is that correct?
Yes, 3.3v will be fine for the rely, there are another wring method, using a power regulator and mosft, i can send it to you if you want
Kady DIY Projects yes. That would be great thanks. I am building one laser engraver taking advantage of my old 3D printer frame and using the same laser you use, a UNO and a CNC Shield. I think that the upside of using a 3D printer are the larger bed and the mechanical capacity for high speeds when moving.
@@sebastiansombra here is the link www.instructables.com/DIY-Mini-CNC-Laser-Engraver/
Kady DIY Projects thank you!
Do you need to add the jumpers on the shield?
How long are the standoffs you used (I have to purchase them separately because I don't have DVD Writers)
is it possible to upgrade the laser engraver become cnc drilling or cutting for acrylic ?
This is very tiny machine, it can't handle such hard tasks
Thanks for the video! One question: what voltage should I set on stepper drivers?
I use 9 V
@@Kady3DPrinting you mean the voltage adjusted with the screw on stepper driver ?
If you mean the voltage i use 9 V 2 A power supply, if you mean the current, make the motor work for 60 second and touch it, if hot, move g
The screw to reduce the current
Very nice video .. If I do the wiring like the video with ralay will it work or will it have a problem ??
It will work prefect but without PWM support
Nice work! Can I use laser of only 100mw 650nm?
Yes sure, but you have make the movement slower
hola amigo los objetos que imprimistes en 3d cuales son sus mediciones xfavor gracias espero tu respuesta que necesito hacerlo
🤩 wow
I have builded a machine like yours but the laser doesnt burn a lot despite i have regulated it to the minimun point with the lens. Only burns a little, but not like in your video. Im using a 12v 2a. How can I get the laser burns more?? Its a 250 mw laser too. Thanks.
Use power regulator to feed the laser 5v and the 250mw from the 12 volts
Hey, very great project, but I have small problem. Can you help me with this project? I use 250mW laser, but laser dot just slightly, and when I run engravingit not burning just slightly light red color. How can I fix it? There is the problem?
Make sure that the distance between the laser and the bed is relevant
Hey! I am going to make this, but I have a problem. I took apart four different dvd drives, and they had only 1 stepper mechanism each. Will it be alright if I use steppers from different drives?
Yes, as long as they are all the right length. Also, where did you get all of your DVD drives? I need another one.
I build everything as per diagram The only difference is relay is using 3 V but gbrl Every time the relay is Activated comes up with an error any advice?
Can i use benbox with this prototype . If yes then how can i install and use the benbox software, please tell.
Hello ! what is the version of GRBL ! Is it modified ??
Hello! I am having problems with the wiring, any maybe with software too. I found the two coils of the motors, but how to connect them well? How do I decide, which goes where? Also, I have the bigger problem: I can't set the borders of the machine. It wants to go out of the world, all away and it overheats because it always wants to move. How to set up software properly?
This videos contain less details. Missing some important data.
Is there Link to get the rods from the old dvd drives, I keep buying some from goodwill but they only come with 1 each making it cost about $25 for 4 metal rods.
how you assembled the T parts? They didn-t come with screw holes
Hi! im building with your instructions and my laser is not getting warm? it shoots a red light and is following the borders of the thing i want to engrave, but the laser doesnt engrave! Could you help me?
That's mean the voltage is not enough, there is another wring method .. read this www.instructables.com/DIY-Mini-CNC-Laser-Engraver/
Wow! I really liked. I also wanted to recreate the model at home but on the video you did not give details about the dimensions of the different parts of the model. Is you sure you can help me with the dimensions?
Check the STL files
@@Kady3DPrinting Yes i already try there, but it does not take out the measurements of each room. To draw i will need measures
Really nice, but I have a question. What are the magnets for?
I have forgotten to explain, it used to stick the paper or the MDF on the bed using another 4 magnets
@@Kady3DPrinting Thanks man! That's a really cool little project. I look forward to trying it out myself!
Does it matter that the spindle of the motors are different? i have 2 DVD but they are diferent, i need help!! please
No, i used different motors too
I made it with Arduino nano but the step motor gets very hot and starting to burn.
I tried to align the motion but same issue...
You could try adjusting the current that goes to the motors. There is a potentiometer in each stepper driver.
You are extremely right, adjust it, move it slowly and try.
i have connected my lazer the way you showed. Even tho the lazer turns on it doesnt carve. What am i doing wrong?
Adjust the space between the laser point and the material
Does anyone knows if the 12V 2A power supply is connected to the arduino or to the shield?
Connected to the shield
Do You need to install The jumpers under the A4988 stepper motor Driver?
Yes, sure
@@Kady3DPrinting have you then used 3 jumps in MS1, MS2 and MS3 pins using the "Sixteenth Step" resolution?
In order not to heat the engines, have you set the voltage on top of the potentiometer equal to 0.6 V?
Many thanks
I have a question
Can I use an old ender 3 mainboard instead of Arduino with CNC shield?
Any board can move steppers will work
@@Kady3DPrinting thanks, I probably will try
el láser no va con algún regulador de voltaje
Great idea, couldn’t find wiring diagram at the comment
I have updated the description
@@Kady3DPrinting Hello. I cannot see the wiring wih the arduino UNO. Could you tell us where is it? Thanks!!
Any chance to build laser with bigger plate? Needs something to engrave skin.
There are many designs on thingversa bigger than that and they use the same logic
Bro I want this machine....can you sell?
How much time it will take to complete one small scetch?
Maybe 15 minutes
Hi maybe someone can help me pls... my relay switches incorrectly...
when the laser should be on it is off, the red lamp on the relay is on and when it should be off both lamps on the relay are on and the laser is on... hope for help!
Sorry i‘am a Bit of noot in Electronics. I don‘t understand the wiring Card. What‘s the big thing in the middle of your wiring Plan? I dont understand how to connect… :(
And what is this track called?It is important for me to know your information about this track, please!
Can it work at fiber and plastic for marking or printing
It may work on slow speed, search for a more powerful laser pen
Hy!
I used the same materials but my laser does not burn.
Do you have any idea what the problem would be?
The distance between the laser and the material is not correct or the power current is not enough
@@Kady3DPrinting I use 12V 2Amp. I kept trying to increase or decrease the distance but nothing...
What i mean is the lasser current, Arduino current is low, there's another wiring method using mosft
@@Kady3DPrinting what is the (mosft)
Hello, i made everything work but when i connect the laser it stops running while making something. The laser also hardly engraves and when i want to make something that’s complicated it also stops running. Can someone help me ? I dont know what to do
What are settings for grbl?
Is there using limit switch for home coordinate?
No need, home it by hand
Wiring diagram shows that laser is powered from 5v line, is this correct ?
Yes
Also there is an advanced wiring using MOSFT and a power regulator
Se usar um nema 17 muda a configuração?
Can I ask will it be fine if you don’t use the heat sink for laser?
Which one exactly? Do you mean the metal container?
@@Kady3DPrinting the laser itself comes with the heatsink (maybe the metal container as you prefer).
@@tamaica7770 i think its mandatory, because it gets hot
@@Kady3DPrinting lol so why not use in your video. I was almost use it without heatsink
@@tamaica7770 i think there is a misunderstanding, i used the laser pen, the pen itself is a metal
Without cooling heatsink, how long these laser can survive ?
I didn’t test it for long time, i got another professional machine, check my latest videos
I want to buy this machine.
How many price in this machin.
if i use a new type cd player motor from a pc will it still work?
Maybe, the motor has 2 or 4 wrires?
4 and also the voltage is dif i think
@@Kady3DPrinting found it on amazon www.amazon.com/NW-Phase-Micro-step-Stepper-CD-ROM/dp/B075L2YFP3 its the motor i have
@@KaanHendek this is better than the motor used at the video
ok thanks
works on arduino mega??
Any Arduino will work
Hello, what did you use as a power source?
9v adapter
@@Kady3DPrinting how many amps?
Why does my laser not opening? TYIA
Could you write me some link arduino and cnc shield and more tools? Thank you!
