Step 9: Final results.

Here are some of the things I made with this little engraver so far. I will let the images tell most of the story. The only limit is your imagination (besides the low power and small work area).

Key chain.
I found some paint stirrer sticks at my local DIY shop. I liked the look of the wood and they were cheap. I saw of a piece and drilled a small hole. After some sanding I engraved the Binford logo from the sitcom "Home improvement".

Plant marker.
A normal Popsicle stick engraved with the plants name.

Personalized matches.
I'm just trying to show off ;)

Memo note holder.
A clothespin engraved and with a small neodymium magnet glued to the back makes a great way to stick a bunch of notes together on the fridge or any other metal surface. I like clothespins they are very versatile.

Stamp.
Cut out of a small foam sheet and glued to a piece of Masonite.

Airplane.
Thanks to scriptster who made the G-code for the model. Check out his model here .

<p>Hi! Can I use an Arduino Nano instead of UNO?</p>
<p>hi there... I was wondering if... I want to use it to engrave several times the same figure: some lines. Is it possible to connect it to the power and put a program in Arduino so I don t have to use the computer? I mean, I connect PC to arduino, upload my little program, and then if I connect the engraver to the power it will work? thank you in advance!</p>
<p>No, Arduino will power on but you will have to use the grbl to control.<br></p>
... thnks :)
<p>No, it won't. Arduino is just like a calculator. You will have to give input in order to receive output.<br>Although you could write a program that will stay on an sdcard and then arduino can repeat that program.</p>
yes, exactly! like this one? : http://www.cetronic.es/sqlcommerce/disenos/plantilla1/seccion/producto/DetalleProducto.jsp?idIdioma=&amp;idTienda=93&amp;codProducto=888304015&amp;cPath=1342&amp;gclid=CjwKEAjw4dm6BRCQhtzl6Z6N4i0SJADFPu1nDCpx0W2rYdx65nX7nO-NEl_Vr1wEsb1NHxrDNYlzqRoCOt3w_wcB<br>how can I do it? ( sd card )... :)))))
<p>Yes with sdcard and lots of coding can do that.<br>Or try searching if someone have that open sourced</p>
<p>Maybe I have not read it pretty well, but I can not find anywhere how much voltage should be marked in the image introduced into the circuit? If you need one at all. The answer Thank you in advance!</p>
<p>That jumper is just an alternative connection for the laser. If you follow the paths you will find they connect to the same as the laser screw terminal. The laser circuit will draw power from the arduino and the Vin pin.</p>
What power supply is should use? How many volt/amp I should supply for whole setup.
<p>How does this work without limit switches? I dont want the motors to run past the length of the rail, causing problems! Also, how do you calibrate the speed of the print, say if you are using a more powerful laser (1.0 W) and you dont want to set stuff on fire... No limit switches are used here so how do you zero the axes and keep the print from going larger than the print area? Also, how do you calibrate the step/mm because with the 53.333 step/mm command given in the project the movements is not properly scaled to the commands. If i put in X10 it will move more than 10mm... Thanks...</p>
Setting of steps depends on what software u r using.<br>If using the given grbl version and controller u jut need to type $ and press enter.<br>That will list all commands that can be set manually. Set first two commands $0 &amp; $1 to 53.33.<br>The author had already described that the inkscape file properties must be st to 38mm*38mm so no limit switch necessary. You can override the stopped manually by using override box in the grbl controller window.
<p>hi, i made the engraver but i am facing a problem, the motion is working fine just needs some calibration but the laser is not burning anything. it is being turned on and off but it just doesn't burn anything what can be the issue</p>
A few things come to mind:<br>1. It is underpowered. How much current are you passing through it?<br>2. It is unfocused. Do you have a focusing lens? Have you tried adjusting the focal length to suit you rig?<br>3. It's not the right laser. Where did you get it? If you got it from a DVD burner, did you pull out the right one?<br>4. It has 'gone LED'... as they say. If you mistreat a laser, it fails and just becomes a nice bright LED.<br><br>There might be other reasons too, that's just what I can think of right now.
4. May be possible because of power fluctuations laser(even with driver) can behave like a working laser but won't burn anything.
Please check if the laser has at least 2.2v and 100mA of power supply.<br>Also check if has focused properly on whatever surface you have setup.<br>Note: It won't engrave shiny metal or glass.
<p>You dont really need to connect MS1 and MS2 on the Easy Driver to 5 Volts.</p><p>The default step setting is 1/8th step.</p><p>From Easy Driver web site:</p><strong>The Easy Driver is able to operate in 1/8th, 1/4, half, and full<br> step (2 phase) modes. These four modes are selected by the logic<br> levels on the MS1 and MS2 input pins. Normally, the pull-up<br> resistors on the Easy Driver hold MS1 and MS2 high, which results in<br> a default setting of 1/8th microstep mode. You can pull either<br> or both to ground to select the other 3 modes if you want.</strong>
<p>So simply leave them as it is(not connected to anywhere) will result in auto stepping? of full, half or 1/8?</p>
<div><div><p>From what I understand, if you leave them unconnected it will be 1/8th step.</p><p>As it says that is the default. I assume if you connect them different ways you will get Full, Half or Quarter step.</p><p>This is the table from the website.</p></div></div>
I'm a newbie to electronics buddy, so don't know this stuff very well. But I found what you said its almost the same as on other site.<br>Quick Specs:<br>Each EasyDriver can drive up to about 750mA per phase of a bi-polar stepper motor. It defaults to 8 step microstepping mode. (So if your motor is 200 full steps per revolution, you would get 1600 steps/rev using EasyDriver.) This setting can be easily overridden by tying the MS1 and/or MS2 pin to ground to set the driver to use 1/8, 1/4 or 1/2 microstep mode (See the datasheet for the table of values). It is a chopper microstepping driver based on the Allegro A3967 driver chip. For the complete specs of the design, read the A3967 datasheet. It has a variable max current from about 150mA/phase to 750mA/phase. It can take a maximum motor drive voltage of around 30V, and includes on-board 5V regulation, so only one supply is necessary. The best part - low cost. The parts cost is easily less than $10, even less if you make the board yourself.<br>http://www.schmalzhaus.com/EasyDriver/
<p>Thanks Groover, you've get me going. After a search on the internet your design suits me the best. I've made it mostly like you did but with a few differences.</p><p>First to mention is the laser. I've used a blue laser pulled out of a RGB laser pattern projector. The power lies on approx 250mW, I think (I don't have a LPM). Blue light transfers more energy so there is more burning power.

<p>Hey Thanks Venkes,</p><p>This is the very good All-in-1 Solution post you made.</p>
<p>Hi dear, I'm really excited about your project, I have read and searched for information to use GRBL but I can not make move my engines with it, will that use &quot;Adafruit Motor / Stepper / Servo Shield for Arduino Kit - v1.2&quot; if engines run libraries move, but if I do not work for me GRBL.<br><br>Do any of the users has made this project using the shield named?<br><br>Thanks I hope your understanding and prompt reply, thanks.</p>
<p>Use the GRBL of the given version or use from grbl's site and the controller</p>
<p>Hi Groover, nice pocket laser engraver. I would like to know what the work area is as I could find it in your instructions. Thanks</p>
<p>Its written 38mmx38mm</p>
<p>Hello you could spend some graphic as you do on and off the laser diode? I think it is a LM317</p>
<p>It is there, its a 5v relay.</p>
<p>ups I forgot also to ask: wich batteries could I use in this case? thank youuuu</p>
<p>Whats Soft i can use WITHOUT Isnkape? It was very stuped on my PC</p><p>Maybe to be any List of soft on PC for using with <strong>GBRL v09.j</strong> (for Arduino Uno library) ?</p>
<p>@jm.instructable</p><p>I think that the &quot;Adafruit Motor / Stepper / Servo Shield for Arduino Kit - v1.2&quot; you're trying to use is simular to the &quot;Velleman KA03&quot; I have experimented with. I coulden't get this one going as well because one cannot send Gcode to it, it seems. </p><p>You can get the steppers running using the Arduino Sketch, but you have to use GBRL and Gcode to stear the steppers in this project. The easyest way for you I think, is to buy two SchmalzHaus EasyDrivers (the're not expensive). This works! </p><p>See the detailed plan in my comment below and the one of Groover above to lighten up things. In my comment you can also see the adjustments you have to make to a few programs to get them correctly running. </p><p>Greets, </p><p>Venkes.</p>

<p>Hi,i try to make this project and i have a question for you , what is meen FAN from electronic schematic </p>
<p>hi, i have a problem like this. i dont find answer in internet (google) , please help me!! </p><p>already thanks for all support :DD</p>
<p>SOLVED! Just download older version (32bit) of inkscape. Worked for me on win10</p>
<p>Change your file path ,liks 'C:\Users\admin\Desktop',I think some </p><p>permissions that</p>
Same problem.
<p>Getting the same error messages. I can't get the gcode prog to function properly either. I'm experimenting with J tech's inkscape plugin, but it's weird when I use a universal gcode sender program, the steppers move, stop and then move SUPER slow, like almost unnoticably slow. After about 40 seconds, they start moving fast again, then slow down all over again.</p><p>the link to the inkscape plugin:</p><p><a href="http://jtechphotonics.com/?page_id=2012" rel="nofollow">http://jtechphotonics.com/?page_id=2012</a></p>
