As manufacturing electronics became much cheaper, more technologies are more accessible for makers, enabling us to be able to create anything we would like.

One of the things I am more passionate about is laser engraving. I made a little research before I decided which technology I would like to use, that will be both affordable and high-end.

In this instructable I'll give you all the information I have gathered, along with instructions about how to laser engrave by yourself and create anything you'd like with it.

Hope you enjoy it, looking forward for your comments.

Step 1: Laser Engraving Machine

When looking for the right laser engraving machine, the most important criteria comes to our eyes is the power. Prior to your purchasing, think about what you want to engrave on. The more difficult the material to engrave on, the more power you need, the more expensive the laser engraver is.

The common powers you should see on the affordable machines varies between 300mW to 1000mW. Since my main goal is engraving on wood and cards I have chosen to go with the 500mW.

Going through different reviews and stores I have decided eventually to go with the following laser engraver:

This engraver usually goes on promotions and goes for really cheap (around 80$). Their 1000mW version should be slightly more expensive, around the 10$ more.

This laser engraving machine has the following specification:

  • Image format: jpg.
  • Image size: 512x512 pixels.
  • Image engraving pattern: Bitmap engraving.
  • Power: Input 4.2V-5.5V 1A
  • Comes with a usb charger.
  • Can carve on hard wood, plastic, bamboo, rubber, leather and more.

I love giving my bottom lines at the beginning, so I'll just give a short spoiler, that this engraver is pretty sick :) Read more to find out how..

Step 2: Unboxing

The engraver arrived within couple of days in a protective box (you can see in the pictures above).

Inside the box you can find the following things:

  • Laser Engraving Machine (assembled).
  • Protective Glasses.
  • Data Cable.
  • Power Cable.
  • USB Power Supplier.
  • Micro SD Card (1GB).
  • A hex key.
  • Instructions.

Step 3: Initial Setup

Time to prepare the machine for our test flight.

This step is pretty easy, all you need to do is removing the nylon and bubble wrap, and removing the duck tape around the bottom board used to hold the material we engrave on, and remove the wraps around the laser pointer.

I have also noticed to some screws that weren't strengthened so I fixed that as well.

Step 4: Safety First

Laser Protection Eyewear

Any device that emits laser light requires us to use addition protection to what we are used to. The engraver includes a laser protection eyewear, which are glasses that are used to protect our eyes since this device emits laser light in different wavelengths. This laser light is consisted of both invisible and visible wavelengths.

Since we're not using a professional laser engraver, I would recommend not even looking into the direction of the machine while engraving. I have seen some people that create a box around the machine, which blocks the light from coming out. Personally, I think that's the best solution.

Still, if you're into looking into the process, either place a camera next to the engrave, or use the glasses that came with the engraver.

Reflecting Materials

Since we're using light, we should avoid engrave on a white material. The white color highly reflects the light, so using laser can be extremely dangerous. In addition to white materials you should also avoid try to engrave on mirrors, lenses and metal. There are special engravers for such materials, it's not the one we use :)

Step 5: Test Flight

Powering up the engraver
Our engraver has two ports:

  • Power port
  • Data port

It is easy to determine between the ports since the power port is a normal USB port, and the data port is a mini usb port. First connect the power using a 5V 1A (PSU is included), and then connect the the data cable to the computer. We're not going to use the computer, but we need it connected so the printer turns on.

Focus Adjustment

In order to achieve better results, we need to make sure the focus of the laser is adjusted to the surface's height we engrave on.

Before we can check if the focus is correct we should place the surface we engrave on right on the engraving board (in our case - the blue board you see in the pictures). Use rubber bands in order to make sure the surface won't move as the engraving machine moves the bottom board.

Once the surface is still, you should see the laser pointer on it. Wear your protective eyewear and start adjusting the focus until you get the best results. I have attached a picture with the focus screw that you need to play with.

"Hello World"

If everything goes right, you should see the laser pointer marks a dot on the paper below.

In our test flight we're going to engrave the default icon comes loaded into the printer, just to make sure our focus is set right, and the everything works. We want to do that before we make things more complicated when we load our own artwork.

Before we engrave make sure you've done the following:

  • Use the protective eyewear.
  • Place the board we engrave on and make sure it's steady.
  • Adjust the focus.

Carving Preview

One click on the button on the top (yellow in our case), will enable the carving preview mode. In this mode the engraving machine will draw a rectangle that shows you the bounds of the artwork it is about to engrave. Here you can make sure that the machine engraves only on the relevant surface and also you can place the surface so you can engrave exactly where you wish.

Start Engraving

Another click on the same button starts the engraving process. Here you should avoid looking directly at the laser, and you just need to wait until the process is done.

In case you wish to pause the engraving click on the button again.


Step 6: Engrave! :)

In order to operate the engraving machine you need to download and install a driver and a software from the following website:

http://www.trusfer.com

Make sure that you download the latest driver & software. It is also possible to download a pack of images that you can play around and engrave as much as you like.

Once everything is connected, and the software connects successfully to the machine, follow these steps:

  1. Drag the image to the software window.
  2. Click on "Send Image to Machine" button.
  3. Click on "Preview" button and see that the size is right.
  4. Position the area as you like, using the arrows.

Don't get nervous about the smoke coming out from the material.

Hope that everything comes out right,

Step 7:

<p>It's a nice instructable, but I kindly leave this link here...<br></p><p>https://www.instructables.com/id/Making-Your-Mini-Laser-Engraver-Safer-and-Better/</p>
<p>I have another version of this unit and CANNOT get it to work w/Windows 10. Emailing the manufacturer is useless.</p><p>Do you know if it will work with Win 10?</p>
<p>i had turned it to work, it easy just install the driver</p>
<p>i managed to get my unit working with win10, try looking around at the ebay sellers of simmilar units, they may offer some alternate software.</p>
<p>Try it via a Windows 7 machine in Hyper-V, VMware or Virtualbox?</p>
It should work on all of them.<br><br>
<p>The vendor's website says it does not work with Windows 10.</p>
I haven't try with Windows 10, I got it work with a VM running Windows 7. I have seen some people here talking about some other programs that work.. Maybe you should try a different program.
<p>wow just like mine but my engraver come with built in usb data &amp; usb power cable ( no port ). bought it from a website for $89 few months ago. good for its price.</p>
<p>Really cool! What is the maximum size of the engraving? The site mentions 3.8 x 3.8mm but it apears to be too small... :/</p>
<p>i believe it is 38mm by 38mm, hope this helps.</p>
<p>Nice work :)</p>
<p>Since you don't won't to use &quot;white&quot; and/or a reflective material, could you place a sheet of wax paper (or something similar) over the 'engravie' (material to be worked on)? Would the engraver cut through to the intended material?</p>
<p>Is this just burnt on or is there any depth in to the material? I cannot tell by the pictures, it just seems like scored wood that would flake off and weather easily.</p>
<p>Great</p>
<p>If you checkout EBAY, you should have zero problem finding a 3 to 4 watt Laser Module along with an included driver. This will enable one to easily engrave Wood, Leather as well as Card Stock with no problem. For Software one should checkout PicEngraver and it's sister programs which will enable perfect engraving.</p>
If you had the eighty bucks to spend on the machine that's awesome but for the sake of instructables can you maybe read the specifications off of the laser module and driver so others and I can find just the laser and then turn what we have into that? I already built an x-y-z multi axis miniature CNC machine, as have many on this website since all you need are cd/dvd rom drives from old pc's but it isn't strong enough to actually exert forces such as dragging this needle point pen on paper or moving the mill bit along to accomplish milling. My solution is turn it into a non contact laser engraver with adjustable beam intensity via the z axis. That is why I ask since your using a professional machine that clearly works. Thank you for your time.
<p>The specifications show 38mm x 38mm that is about the size of a postage stamp 1.4 in. Seems very limited for such a cool looking device. Anyway to use the full range of the steppers?</p>
<p>This is advertising. The only DIY is &quot;Step 1, open your wallet.&quot; <br>I purchased one of these in November. It arrived from China in January and died a week later. While under $200, it was bought as a small desktop &quot;toy&quot; to keep my head focused on what the possibilities can be, as a visual. </p>
<p>This is advertising. I purchased one of these in November. It arrived from China in January and died a week later. Prints thumbnail sized images. A neat toy, or visual to keep on your desk. </p>
<p>Where is the DIY?</p>
<p>You said at the opening that this laser is pretty SICK? Or did you mean slick?</p>
<p>I recently got a laser engraver/cutter like yours, And tried downloading the softwares for designing.</p><p>My computer's antivirus tells me that all of the different softwares and apps contain viruses, So I can't down;oad them. Do you have any idea for what to do?</p><p>Thanks in advance :)</p>
<p>Usually I don't take a risk and I just run it from a VM. Use a dedicated VM for this one, or just run take a snapshot of an existing VM. I don't trust antiviruses, but I won't take a risk :) I ran it off a VM and it seems ok.</p>
<p>There is no virus, is because a chinese software always will be like a tread for any browser, antivirus, it seems to work with an arduino clone and grbl 8 because interfacing with serial speed of 115200 b/s gets error and the program crashes, I'm pretty sure it will work with 9600 b/s</p>
<p>Thanks, I'm not sure I know what a &quot;VM&quot; is after Googling it. What VM do you use?</p>
VM = Virtual Machine
The software is free? I'm using: Inksacpe with a plugin works well but I need something better or with more options to engrave, I made my own machine with 445nm laser (blue laser) ,The hex key you mentioned is to have access to the software?
Hex key is another name to Allen key.. The software is free to use, you should give it a try :)
<p>LOL right</p>
hello the machine can engrave metal ?
<p>Nope, this one cannot do that. </p>
