Hey everyone! I don't know if you're going to see this video.

There is another big box that just arrived.

What's in the box? It's a laser cutter. I purchased it before my Patreon got shut down.

I finally saved up enough money to buy it.

But guess what? Unfortunately it's not the best time to waste more money.

But it turns out there is no way to return it or resell it. So I'm going to make the most of it.

I am going to shoot some videos to show you the specs of the machine.

Show you how to use it and also in Shenzhen there is a flea market every weekend.

Maybe I will apply and I can make some small projects and sell it there

and make enough money to make it up back to the money I spent on the laser cutter.

As you can see, this is a very big machine.

It's about 232 kilogram and it's over 500 pounds.

For a small person like me of course I'm not gonna hurt myself.

But the delivery boys they're very nice I made a small deal with them.

I cook lunch for them and they're eating in the hallway and I pay a little bit of cash.

They're going to set it up for me and put it at the corner.

So I am not even bother to touch it. But after they set this up, I'm going to show you how to use it.

Right now I'm going to show you some specs of the machine.

So what I got is a 40 centimeters by 60 centimeters laser cutter.

It is made by a company called JingKe. It cost about 11,000 RMB.

So it is about 1,750 US dollars. It wasn't cheap, it is as expensive as a laptop or maybe a very good 3d printer.

And I did some research on the power, settings and something like that.

I decided that 80 watts would be about right.

It has an offline controller which means you don't have to run it attached to your computer all the time.

It has its own controller.

This is what the laser cutter is going to look like once I unbox it.

On the back there is a big black square, a big black box actually it is holding the laser cutting tube.

And the more powerful tube you have, the longer it is.

It is kind of annoying because it is very hard to fit it anywhere.

The ones you see that are more compact have much smaller maybe 30, 40 or 50 watt laser cutting tube.

So there's nothing much I can do. I can't shorten it.

Sometimes you can specify the color. Because they put everything together kind of by per order.

But I don't think that's that important.

But definitely get wheels a lot of people told me it is heavy and it is.

So I got the wheels. It helps me to move it around easier.

Now there are different packages available. I got one of the better ones.

It comes with offline controller which we already discussed.

And you use a program called a LaserCAD to help you figure out where the line is.

It says what kind of generator it has. The quality of the tube and the kind of power supplies it uses.

I think that is power conditioning and the other features the unit comes with.

But I am not quite sure on the Chinese - English translation.

It has something called the Z lift which is automated which means to goes up and down

you only need to push a button. Some machine comes with a crank or no Z height adjustment at all.

And it uses linear slide instead of rods which is much more accurate, same is with 3D printers.

There are stepper motors. It comes with a chiller instead of one of those cheap aquarium water pumps.

And it has a rolling thing. I think you use it for a bottle or a round bamboo objects.

I'm not sure, something like that. That was an option.

And with all their features from 50 watts to 100 watts.

There are different price ranges but as I said I settled down on 80 watts.

Voilà! Like magic right? No no it has been a week since the delivery guys came and put it over here.

I also got some other helpers some helper elves. This is not a one Naomi project.

I can not do this alone. Anyway it is all set up. Looks like it.

I got overwhelmed. I thought I would just use it and then I realized I don't know anything about it .

So I have to check the manual first and then I have to maybe check out a lot of videos.

Watch them and learn how to use it. So this video is probably going be a little bit choppy.

So be a little bit patient with me. As I go along I'm going to learn how to set things up.

Laser cutters can be very dangerous so I don't want to be careless, I want to be cautious.

They gave me the exhaust fan. I'm sure I got to put it somewhere. And I have two tubes here.

I am going to put it outside my balcony. I think this needs to go outside.

Because it's for the smoke for ventilation.

Here I also have the air pump.

And here is the cooler. It keeps the laser cutter cold.

So I got this hose online. The machine comes with its own hose.

But I think this one is a little bit better so I'm going to use this one instead.

Ok this is just a super simple T-connector that I made in Tinkercad.

It is literally two or three cylinders combined together and then subtracted.

It's very handy. Now they have something that fits.

If you have a 3D printer definitely consider printing your own T-connector or whatever connector you need.

Because they will make everything go together much more smoothly and it is a very easy part to make.

I'm going to use this tape to tape around the hose.

I'm not sure if this is the right tool, but I have tons of it hopefully it works.

Okay I'm using a little bit of BluTack to wrap it around the T-connector.

I am just going to wrap it around and then push it down and then press it against the hole.

I don't really want to tape it around the machine.

Because I want to be able to put it away easily when I have to do something and I use BluTack on a lot of stuff.

So this is the laser tube. I'm going to remove the shipping foam.

I saw some pieces of the packing foam left. I'm going to vacuum them later also.

I think for now I can just put the hose like this on the balcony.

But it's not a very good solution. I will think of something better.

Maybe I will show you the whole process step by step in another video

But I just want to show you quickly. What I did is I modeled the parts.

It goes from round tubing to a rectangular slot to go through the opening in my sliding door.

And I didn't write all this code. I just pasted it in from the Internet and changed a few variables.

I can do the rest in OpenSCAD too. But it is just easier to do it in Tinkercad.

So what I did then I just imported the part and added the round bottom and the square at the top.

It only takes me a few minutes. Again CAD is kind of its own kind of video.

If you are curious on how to model badly between multiple CAD programs instead of using one program to do all of them.

Maybe I can show you in the future if you are interested.

I am printing the model on my Creality 3D, Ender-3.

As many of you know, I am sponsored by Creality 3D.

And I have been using it for everything and it has been great. It is a real workhorse.

If you are interested in one I'm going to put the link in the description box.

It is about $200 at gearbest now. It is a very good deal.

And I'm printing now half of the prints. And then I'm going to put it together with gel super glue.

I do it a lot. It is as strong as it was in one piece. Sometimes stronger, depending on the orientation of the part.

It seems fine. I am not going to tape it right now. Because later I might have to move the laser cutter.

So I'm just going to leave it like that.

Alright now I am going to add the water into the chiller.

This has been filtered by my Xiaomi filter I think it is clean enough.

I got to be careful. Because the pump is right next to funnel.

The reason I'm pouring it in. is because the water in the chiller keeps the laser tube, the CO2 tube from overheating.

So this is a very important step.

Ok I've watch a lot of tutorial videos on how to do this.

And I've asked my friends a lot of questions. I think I'm ready to go.

But it is my first time so I got to be careful. I even got a fire extinguisher in case something bad happens.

Anyway it is a dangerous machine. I think everyone should be careful.

So I'm not going to turn on the laser part. I'm just going to open the machine first.

Alright you can see there are some zip ties on the X axis.

I am going to take them off.

Let me try another one instead.

Alright looks like there are no more zip ties and now let's turn it on.

Right now the laser is homing.

I think there is a sample inside. I can use that file.

I am going to test it with the cardboard first.

I can turn on the red button to see the laser light.

And then I hit box.

Then I know the range where it is going to cut.

In case anything happens, I still have my fire extinguisher.

Let's hit start.

The maximum power is 50% , minimum power is 40%.

It's pretty high.

Damn I can see the fire. I think it's fire.

Holy smoke, holy smoke.

There is a lot of smoke. I am going to put it in the sink and try something else.

I got this wood here. Right now I don't have any acrylic, I am going to order some.

But this is the only piece of wood I can find. So I am going to test this one.

With the same file.

So this is the result.

I don't have any extra materials. I think I am getting somehwhere.

I will try to watch more videos and see how to load the file in the machine.

And cut something for myself. Remember if I can do it, anyone can do it.

Even though I am not there yet. but what I'm able to do it, you can do it too.
