This machine is designed to make the laser engrave in wood and opaque plastic, having an Arduino and the GRBL as machine automation basis. The machine axis are just the X and Y axis, which move a laser with power 1w 445nm, and this article aims to provide everything you need to make, without waiving of mechanical and electronic knowledge.

With around 170 euros can make one.

Step 1: Materials

You will need some material for your machine, in which I produced a list of required material. You will need tools.

Bill of materials:

1x Arduino Uno

1x Motor Jaw Shaft Coupler 5x5mm

1x Laser 1w 445nm (you can choose another, but i recommend max 3w on this cnc)

1x CNC Shield v3.1

1x Laser driver 12v

2x stepper motors Nema 17

1x power supply 12v 5A

1x laser diode 1w 445 nm 5.6mm

1x heatsink 5.6mm laser diode

3x GT2 Timing Pulleys 20 tooth 3m GT2 Timing belt

1x 12v fan cooler

1x 605ZZ ball bearing

12x Pulley Wheels Roller 695ZZ1x 5.6mm TO18 Laser Diode Case

2x stepper motor driver DRV8825

2x limit switches

1x switch power 3D printed pieces

1x plugin 230v cable

1x USB cable (in future we will use Bluetooth)

M5 Nuts

various length of M5 screwdrivers

flexible cable wire for electronics

1x pair of safety glasses Note: Never look directly into the laser, always wear protective glasses, link these glasses are cheap and effective, look directly at the laser runs the risk of blindness and cataracts. http://www.dragonlasers.com/Laser-Safety-Glasses....

On Rat rig:

5x 500mm V-SLOT 2040 – Black

8x OpenBuilds Universal L Brackets (Single)

1x OpenBuilds Tee Nuts (25 Pack)

5x OpenBuilds Tee Nut (1 Unit)

<p>You can cut acrylic?</p>
<p>You can/t cut acrylic with a diode laser you will need a CO2 laser</p>
<p>Here is my copy of the arduino laser engraver</p>
Love your laser.. have more pics or videos on what it can do? Where did you get the instructions or did you do it on your own? thanks..
Its based on the instructable these comments were posted to.<br>I dont have instructable detailed pictures but can email STL files if interested.<br>
<p>send them please to bestbuy315@gmail.com</p>
<p>hello, where did you buy your laser diode ? can you give me the website please ?</p><p>thank you , great job</p>
<p>hi awsome instuctable ,but i cant find the bearings you used ,can you share alink </p>
Hi<br>Can you explain the need of the resistor between the TTL lines? <br><br>Thanks!
<p>Do you mind to inform the stepper motor torque ? Congrats awesome project</p>
<p>Why is there a resistor between the positive and negative TTL lines? Won't that short it?</p>
With these parts maybe?
<p>Nope. You need a mirror system for the big laser. The fact that you ask means: stay away from that device. And don't forget to print a warning: &quot;Do not stare into the laser with the leftover eye!&quot;</p>
Lol, fair enough
<p>If I have cut acrylic what is the wattage of the laser(minium) should I use? If anyone could point out to reliable international shipping source(s),it will be really helpfull :)</p>
It used to cut cardboard?
Hi, could this be modified so that it could cut? Brilliant instructable! Thanks
Nice work!<br>Thanks to share.
<p>Thanks :)</p>
<p>Thanks :)</p>
<p>Complimenti, che velocita in mm/min usi? come fai a eseguire la scala di grigi?</p><p>Grazie</p>
<p>Very nice work. Do you have a link for: Pulley Wheels Roller 695ZZ</p>
<p>Hi thanks, credits for you! </p><p>http://www.ebay.com/itm/12pcs-HR-0523-7-5-Furniture-Plastic-Ball-Door-Pulley-Roller-Wheels-695zz-Bearing-/221982161419?hash=item33af2afa0b:g:QW8AAOSwA4dWJzEm </p>
<p>Hmm, doesn&acute;t ship to Germany.</p>
<p>Same pulley from Hong Kong, ships to Germany</p><p><a href="http://www.ebay.co.uk/itm/10pcs-Miniature-Metal-Shield-Pulley-Wheels-Roller-695ZZ-5x23x7-5mm-Ball-Bearings-/231591101773?hash=item35ebe7c54d:g:rn8AAOSwBahVepBa" rel="nofollow">http://www.ebay.co.uk/itm/10pcs-Miniature-Metal-Sh...</a></p>
<p>really? :/ that's bad</p>
<p>Thank you ...^_______^</p>
Hey, <br><br>To which size did you cut the v slots? Does it actually matter or can I choose the size? <br><br>(PS: I think you forgot to mension the rod for the x-axis) <br><br>I'm definitely going to build this! Thanks for your Instructable.
<p>You can choose the size, i bought 5x 500mm 2040 on Ratrig Portugal, they ships to UE. No i don't forgot, 5x V-SLOT 2040 &ndash; Black ;)</p>
<p>I think you misunderstood :) with rod I mean something like this (found in tobias.sobkowiak's instruction):</p><p>http://www.ebay.de/itm/181470570665?_trksid=p2057872.m2749.l2649&amp;ssPageName=STRK%3AMEBIDX%3AIT</p>
<p>That looks awesome! What is the head's top speed?</p><p>Have a great day! :-)</p>
<p>i'm in tests right now, when i finish i will post :) </p>
<p>The link to 3DP Burner are wrong, it point to Xloader</p>
<p>sorry, i don't know why it happens... it's fixed now.</p>
<p>I have been looking for something exactly like this.</p><p>Thanks so much.</p>
<p>Thank you, try :) any problem ask</p>
<p>Now, the next obvious step - replace laser with a sun. Have to solve intensity control somehow...</p>
<p>You can control in software (0-255) and with hardware on potentiometer.</p>
<p>Hello<br>Thank you for the inst. Could you please fix the &quot;https://dl.dropboxusercontent.com/u/40132197/M.%2&quot; link? :D</p>
<p>Hi :D thank you :) it's fixed</p>
<p>Still is not correct.</p><p>CamBam settings: https://dl.dropboxusercontent.com/u/40132197/CamB...</p>
Nice work!
<p>thank you :)</p>
<p><a href="http://www.thingiverse.com/thing:819755" rel="nofollow">http://www.thingiverse.com/thing:819755</a></p><p>Thats the right link for the files...</p>
<p>fixed :)</p>
<p>Just a fair warning to everyone.Don't know if it's mentioned in his instructions,but you should NEVER!!! laser cut or engrave any PVC products as they produce poisonous gas that can be fatal.</p>
<p>It can't cut PVC... Only engrave some plastics, have only 1w...</p>
<p>That is good project </p>
