Hello everyone, in this manual, I will show you how you can successfully convert 3D printer to complete laser engraver for less than $40
To start this project, we need a laser that is strong enough to burn into most household materials.
I have found that the 500 MW laser is suitable for this project, as its price and engraving capacity apply to almost all materials except metal and glass. -
I bought my laser on the AliExpress for a small price.
Here is a link: laser, you will also get a laser drive circuit and a safety glasses when operating with laser. -
So I first removed a small fan attached to the plastic holder, and then unscrewed a 3d printer
End from the same acrilic Mountain. -
I then cut two zippers, fixed the 3d print tape in place, and then removed the last screw so we could drill two holes on the plastic holder. -
There are 4 holes in the laser module
Drill, so all I need to do is drill two 3mm holes on my bit. -
I used two small screws and I found this screw in my screw collection box, but you can also use two screws attached to the fan on the back of the laser module. -
Now, I\'m putting everything back together, with a new pair of zip straps. -
After reinstalling all devices, connect the laser input voltage to the fan port of the 3d printer motherboard.
I\'ll explain later in the video why we\'re doing this. -
This is the solution of the laser driver we receive with laser.
Connect the fan on the laser to the cooling fan port, connect the laser to the laser port, and connect these two wires on the 3d printer motherboard to the 12 v power port.
Please do not insert the TTL Port because we do not need it. -
Now just turn on the fan in the 3d printer settings and start all the axes automatically-
Keep in mind that you need to adjust the focal length to the height of the engraved theme. -
The final step is to carve a small starting point on the painter\'s tape so that we can know where the zero point of the x-axis and the y-axis is. -
The engraving software I am using is called Inkscape and you can download it by link: You also need an Inkscape plugin called inkscape laser tool plugin
There are also links here: Download these two files, install inkscape, and copy the files of the inkscape plugin tool to the extensions folder of the inkscape program. -
In the program, first define the print bed diameter and drag the logo you want to engrave.
Set its x and y to 0 and use the trace bitmap command: Path-vectorize the image> Trace Bitmap-
Just enter now: extension-
> Generate laser G-code -> J Tech. . .
And set the laser on/off command to m106. this is the command to turn on and off the fan port where we connect the laser. -
The laser speed is also very important, and I think the perfect speed is 100 to 300mm per minute. -When our G-
The code is ready, drag it onto the Sdcard and print G-
Code in the 3d printer menu. -
We can easily cut any type of paper and the best part is that you can carve your logo with any leather, wood or plastic material. -
You can also cut the foam and carve anything on your smartphone case or tablet. -
Always have the option to buy a more powerful laser if you want to carve faster, but it will also cost you twice as much.
