Thanks for watching! I have linked the CAD files for this project below as well as some of the links to the hardware I used. I am very happy with how this machine turned out and will definitely be using it in future projects. I think this laser cutter costs around $1000-$1200 in parts which is less than half of what a commercial option would be. If you are looking to replicate this project I would urge you to do as much research as possible and use my files as a starting point. Laser cutters are extremely dangerous (but also awesome) so do it at your own risk.

Overall for metals you'd want a Q-switched laser as you need very high power density, instead of trying to give this power all the time, you can use lower average power but in pulses so it has a lot of energy in short amount of time so heat doesn't have time to get transferred to the rest of the metal

Also, the results you were able to achieve with aluminum powder are really surprising.

The part you mentioned about minimum operating wattage for CO2 laser wasn’t something I had heard yet in other comparison videos. The speed of a CO2 laser was starting to make me consider going for that despite the drawback of being much bigger and less mobile until you mentioned how it might over engrave in some situations and I’m mostly looking to do engraving at this time. Thank you for the entertaining and informative video!

@SarbarMultimedia Жыл бұрын

Hi Miles There is a lot more to laser technology than Michael shows. I applaud the effort he has invested in creating a great little machine but has only just begun to play with it. It's a long journey to tease out and understand all the pieces of physics, chemistry and optics that explains what you see. Your personal need seems to be engraving but that single word covers a multitude of different processes such as normal raster engravng, photo engraving, deep engraving, 3D engraving, grayscale engraving, metal marking. Add to these all the materials you might want to use such as wood, leather, card, slate, glass, acrylic, ceramics or MDF and the situation becomes complex. Some materials react well to CO2 wavelengnth light(10,640nm)and others better at 450nm diode laser wavelength,. If you just wish to surface mark organic materials then the cheap simple diode laser is perfect for the job, but very slow. Organic materials are fairly resistant to stimulation by 450nm wavelength light and thus scorch easily with the low power available. However, cutting is a side act that it does very inefficiently and even more slowly, Some materials such as acrylic are transparent at such low wavelengths Michael is right when he says that a CO2 laser tube does not deliver power down to zero watts, but i suspect he has not yet discovered that his tube has a secret low power operating zone called pre-ionization that is amazing for precision photo engraving, glass engraving and burn-free paper cutting.. Until you start exploring the technology for yourself you will not understand how difficult it is to precision scorch with a CO2 beam at 10,640nm . A small format 500x300 50 watt CO2 laser (like Michael's little baby) is the most flexible system you can learn with. At 10640nm ALL metals are like miirors so you cannot cut metals or engrave metals with a CO2 laser (I have tried ...oops). but this is the most universal wavelenght for general small business or hobby use. Good luck

@Jakefrc Жыл бұрын

If your C02 laser is over engraving, you just need to move it faster. I run mine at 400mm/s for light stuff. Gets the job done really fast as a bonus.

@SarbarMultimedia Жыл бұрын

@@Jakefrc Hi Jacob I wish it was that simple.There are so many features that make your machine unique. The most important being the light intensity distribution within the beam .A good beam will be about 5mm diameter with a Gaussian (or bell curve) intensity distribution. Many machines will be using B grade tubes that are all over the market and certainly fitted to ebay machines and Amazon market place machines. They work "in some way", some better than others but they will have have a totally unpredictable performance that falls way short of perfect. Be pleased that you have found parameters that work for you but that does not mean it will work for others.. Engraving means careful control of low power to allow organic materials to scorch rather than cut. All lenses are cutting tools and it is difficult to find ways to prevent the vapourization that happens at the centre of the beam.. In priciple you are correct, that by increasing the head speed you are decreasing the exposure time for the beam to do damage. and that should create more scorching and less cutting. However there are other factors that come into play , such as the lens type and focal length plus how well you have focused your beam (or defocused it for better engraving).. If you wish to understang more about the difficulties of surface engraving of organic materials ther are explanations an demonstrations here laseruser.com/the-concise-rdworks-learning-lab-18/

A few things to try with different air assists: Co2, n2, or argon to make cleaner cuts, with less smoke marks O2 at high pressure to cut steel. For steel the O2 is dong the cutting, the laser mostly provides direction and the initial melt.

@marcus_w0 Жыл бұрын

But you need a lot more power than theis whimpy 50w tube - for cutting steel, there are commercial CO2 laser cutters - but they start at 150w and have a special cutting head - presumably because of the high pressure. Anyway - if you want to laser metals, you should opt for a YAG laser - for a very different price, of course.

@mikegrok Жыл бұрын

@@marcus_w0 I have not seen anyone test a 50w laser, but someone did cut steel with a 20w diode laser and more compressed air. The different head may make a difference, the head is much closer to the material, and may actually rub it. ie if you did this, you may need a shroud. The big difference is the presence of oxygen in a bottle going into your air intake.

@epilotdk Жыл бұрын

You don't use high pressure O2 to cut steel. Typically the pressure is below 1 bar. However you do need the correct metal cutting head to maintain consistent height over the sheet when cutting. Messing with O2 is very dangerous so anyone planning to do so should educate themselves well about the dangers before attempting it. Good air pressure and the correct cutting surface is the key to reducing smoke stains, no need to used expensive assist gas.

@mikegrok Жыл бұрын

@@epilotdk my previous experience was cutting steel 2 inches thick with a gas torch. The heat of the torch melts a bit of the steel, the oxygen mixing with the molten steel is very exothermic, and provides the rest of the heat needed to melt through the steel creating the cut. From watching other people cut steel with a co2 laser, I was hoping it would be similar.

@epilotdk Жыл бұрын

@@mikegrok It's true that an exothermic reaction is created but when laser cutting with O2 as assist gas, not a lot of pressure is required to get the reaction going. I do laser cutting for a living.

I actually think there's some potential with the metal, there. I met a guy in 2008 who built a metal 3d printer. It worked by using a hacked inkjet printer to spray adhesive onto the layers of powdered metal. Then, once the print completes the part would be dusted and put into a furnace for sintering.

@krisknowlton5935 Жыл бұрын

If you go and watch one of the videos on RD Learning Lab Russ talks about this very topic. He shows how the energy is completely absorbed by clear acrylic. It all depends on the wavelength of the laser light. CO2 laser light is invisible to your eye whereas the blue diodes are visible. Clear acrylic and glass are both transparent to blue diode lasers but not to CO2 lasers. That is why you can cut clear acrylic and etch glass with a CO2 but not with a blue diode laser (you can etch glass with a blue diode laser but you first have to paint it black or use candle black to coat the glass)

@streaky81 Жыл бұрын

In re sintering it'll probably soak up epoxy like a sponge - and will be extremely strong afterwards. This is actually an approach used by some commercial machines. I don't think sintering metal is where it's really at anyway but plastics more: same deal with epoxy but maybe not needed. These sorts of powers being able to semi-sinter aluminium for a home gamer might actually be a big deal, possibly even a game-changer, all you need on top of that would be a powder hopper, build box and a spreader, to wit there are open source designs available.

One can connect all four steppers in parallel to the Stepper driver, sharing the same signal, make sure their direction of rotation is same and driver current setting is appropriate. In this case no driving belt or toothed pulleys are required, each screw is driven independently but simultaneously in the same direction.

CO2 is perfect for engraving, you can engrave a piece of paper on 40W CO2, or do a 1mm deep engraving for filling with other materials. It will engrave on almost any material including clear plastics (and make a deep engraving on clear). It's also much faster than diods, so you can engrave bigger things in reasonable time. And for engraving you usually don't need such a big machine

If the CO2 won't turn on until a certain amount of power, would speeding up the cutting speed overcome melting/charring the material? I'm still researching if I want to go this route.

You're on the right track, but from my research ( I only have a diode) higher speeds introduce other issues. Sorry that's vague.

Thank for the video. Just 1 thing I disagree with you. Co2 laser can engrave as nice as diode laser. It's even better as you can generate 3d effect on surface. So when you have a co2 laser cutter, you do not need something else. The only issue is the limited size of work as if you cut far from laser source, power is decreasing. So maybe you have something in marling that take count of it.

Merry Christmas. Nice Homemade setup. What software did you end up using with that controller board with the LCD screen? did you have to make Not gate circuit to convert the board PWM to run the lasers power supply? I know many laser PSU Are 5V for off and 0V for full power, in my case I use a one transistor 2 resistors not gate to run mine, but i use a normal Arduino Uno and a CNC shield with GRBL 1.1E no fancy screen but a laptop with Lightburn that pretty much controls it.

Isn't the latest version of GRBL 1.1h ? Notice any differences between 1.1e and 1.1h if you've used both?

@patprop74 Жыл бұрын

@@jarodmorris611 Yup you are right and i am using Ver 1.1h and seeing i was sure I was using 1.1e which I'm sure at one point i was,, But no I don't think there is much of a difference, the real change came from 0.9 to 1.1 with the option of using the end stop pin to PWM the laser's output, I think, but its still early in the morning here my brain may not be working yet hahaha

Could you clarify where you got that cut bed? Im looking but not finding much to fit this size.

the diode laser, even with minimal power (just enough to cut the first layer of paper), still doesn't give a good result? On foamboard ..

Do you think CO2 it can cut a 3mm thick aluminum sheet?

Do you think it can cut glass? CO2 laser?

How is the power been set for the laser? could you share more information about that? nobody on the internet seems to know how to hook the board up to the laser power supply. thanks

I would like to know that as well, I am stuck at that part
