- Hello! How do you do? Today I will show me latest build, diy 40w CO2 laser cnc machine, for engraving and cutting different material, such as plywood, wood, acrylic, it's made on arduino nano with GRBL, pretty much all of the components ware bought on Aliexpress, CO2 laser tube, rail guides, power supplies e.t.c Hope to inspire you to make your own CNC!
List of all components: docs.google.com/spreadsheets/...
Support me on Boosty (and get a 3d model of CNC for Fusion360): boosty.to/how_todo
More information in the instructables: www.instructables.com/id/DIY-...
Despite the fact that my English is almost perfect, maybe you could notice a small Eastern European accent, it's because I'm Russian, and answering the question "why don't you make videos in both languages?" I actually do, and my Russian channel is here - / shhitov

Excellent video showing a bare bones low cost co2 laser. Great place to start and then add features. Thanks for sharing
Thanks for sharing. The Arduino community is great. Always interesting ideas to get inspiration.
Forgot you was a TH-camr. Glad you're back!!
Great job. You really inspired me with your simple yet excellent design.
GREAT job! Very informative! thank you
Great job, thanks for sharing!
Thanks some very useful practical tips given
Nice. I'm in the process of building my own machine and this was interesting. I'm using a JH 50W tube to begin with, but plan to also make my own larger cavity if I can find resonator mirrors. Nobody seems to sell them at a reasonable price.
nice work!
thanks for sharing great video, really
Thanks for sone awesome videos 🎉
nice. i want to build one of these for long. maybe i will do so soon :D thanks for the video
Did you build it?
Hello Konstantins 🎉
I'm hoping you can do an update on 32bit boards with laser control.
keep awesome
Hey, will we get the 3d model for the 3d printed parts if we support you?
Can you please convert this to an esp32 bit microcontroller I really wanted to make one for myself using 32 bit for much higher speed also can you make a rough estimate for how much speed you can achieve using esp32 in this machine
Can this build engraver stone?
I build cnc laser too
Is this...or the maslow cnc!

Saludos, tendrás el diagrama de conexión ? gracias
How do i laser cut a stainless steel sheet of 0.8 mm thickness?? Please answer
Can it cut plexiglass?
Hi Constantin, Perfect project, along the lines I'm hinking of making myself! I try to support you on "boosty", but it wants a telephone number as the first step. My number aparently does not fit their requested pattern, plus all is in russian language which I unfortunately don't speak. Any hint for the stupid on how to still support you?
heyy can you please explain how to make a coilgun with more than one capacitor do you need a higher voltage supply or it will just take longer to charge and i was thinking using a car ignition coil for power supply does it work anyway nice work keep up :)
If you wanted, you should wire the capacitors in parallel. And you shouldn’t need a bigger voltage input bc the capacitors fill up almost immediately, around 6 time steps depending on the capacitance of the system
freaking HALF A YEAR! Are you serious man? I almost forgot that your channel exists.
Let's say I've been building this CNC all this time..
@@HowToDoEng he got a point
I want to make 5 axis CO2 laser machine Kindly help me and which software I use for operation in my 3d model and what firmware I can use for operating my machine
can cutting 1mm metal sheet from this machine?
pwm frequency????
Awesome video man! One thing confuses me; I understand for raster the beam is pulsed to create the different shades or lots of little dots, but for continuous cutting of something like acrylic, how is the total output power of the laser controlled? Is it constantly at 40w output or is there control for that somewhere in GRBL too? Is it simply the travel speed that determines how long the beam dwells on one spot hence the desired cut depth can be achieved? Cheers man
Thank you! I never use full power of 40w because it's not very healthy for laser tube, better use slower speed and less power. Arduino can change power wia TTL signal, you just need to set the correct value of power and speed for each line, for example to cut 3mm acrylic or plywood I'm using speed of 7mm/s and 37% power.
@@HowToDoEng Ah cool, Thanks! So TTL is a pwm or analogue signal in? Makes sense.

Can I use gt2 6mm belt for x and y?
Because it is only available in my place!
Salve ti scrivo dall'Italia, vorrei farti alcune domande: 1) Fino a che spessore può tagliare il legno, 2) C'è un programma compatibile con Windows 10, 3) Quanto e il costo totale della CNC che hai mostrato.
A riguardo rispondermi puoi farlo in Russo per cui userò il traduttore online. Grazie
Can you.make and ship.one out?
Hello, I'm follow you! You made cool machine! Do you mayd anythink on it? What did you do from him?
Add about 300$ for a proper DSP and drivers for the steppers and you got a winner.

Nice low cost build :) ** Really important for safety on you lower surface in particular put a piece of cold rolled steel sheet down over the wood before you have a fire.
Shared here btw :) rdworkslab.com/viewtopic.php?f=159&t=4735&p=25606#p25606
be careful with metal underneath the beam. IR Can reflect off of a lot of surfaces and cause you, or someone in the vicinity a lot of trouble....
What are the yellow things on your 3D printer? What is their function?
Those are inserts that are just for looks, they come with the Creality CR10 printers in blue or yellow.
Hello. Great work. May I ask you to buy build guide and STLs without subscribing? Thank you
You use 17 nema motors ?
Yes
How many W does a laser need to have in order to cut metal ? Something like 0.5cm in thickness
To cut that kind of thickness ur gonna need a industrial fiber laser. $100k+ or a not as precise cnc plasma cutter
hi boss
How many watts of laser cutter will you need to cut a maximum of 1 mm of plywood. Small diy is for work.
please reply
Plz send me connection of laser power supply to arduino
Hi, I have a K40 CO2 laser, I have problems with the controller, and I would like to change to ARDUINO, will you have the schematic? , Thank you.
I subscribed to be aware of your tutorials
Arduino is so and so... If you want a real upgrade go for the Cohesion 3D board. Not cheap, but a better upgrade. You also get real PWM. And is pretty simple to do the upgrade.
Have you tried cutting metal with it ? I'm looking to make my own, but to cut up to 3mm stainless steel, and aluminium.
Nope you cant cut metal with co2 laser
Plz sir shared the codes
Спасибки. Хоть понял, как CO2 лазер применить
Why not make a 3d laser engraver.. Basically your same set up on its side.. Computer controlled rotating dish in front of it.. Metal plate behind dish for safety... Laser starts at top of 3d object.. Dish rotates and laser engravers based on the design.. After a full 360 degree etching laser steps down to the next pixel and does another 360.. All the way to the bottom.. You could use it for basic shapes such as primitives, like cubes, cylinders, spheres, cones etc...
You could unwrap the model with an unwrap program.. Loads of those exist.. Feed the image to the laser and get it to draw the corresponding pixel in the right location using the above method...
Can you make this in English? Thanks
I didn't expect a long-winded diatribe on the laser etcher, I was just hoping you would have shown what you made and the process of building it.
