Picture of Pocket laser engraver.
I have been trying to get my hands on a laser cutter for some time but they always seem out of reach. All the great things that can be done with a real laser cutter tickle the imagination.

I feel it's time to share my latest project - a low cost laser engraver,. The workspace is a bit small but none the less it works and comes so cheap that most will be able to replicate the result. I did take a few shortcuts, as I feel I don't have the knowledge to do all the electronics I opted for readymade but low cost in favor of trying to make my own (and most likely fail). All parts used are however easy to find.

I am pleased with the end result even if there is room for improvements. The small size and low power is a bit limiting but I have made allot of fun things already. Paper cutouts, plant markers and stamps among some. The engraver itself might not fit in a pocket but the workspace limits what you can do with it to fit in the pocket.

A word of warning is in place . This instructable is using a ~200mW red laser. It might nut cut through chunks of wood but it will make you go blind if you are not careful. Never look into the beam, even reflections can be dangerous if focused. Please be careful.

I was thinking of doing something similar, but the worm gear style drives didn't seem like they would have enough resolution. Now you've got me rethinking this assumption.

hello, i have arduino uno and Adafruit_Motor_Shield_V1 . Do think is it possible make this project? what kind frimware i should use? Thanks

can i use L293D instead of easydrivers (cause they are damn expensive)?

Cool project! I'm trying to do the same, but with a scanner and printer instead of DVD drive parts.

I'm attempting to do the same. Did you end up getting anywhere with it?

Unfortunatealy, no. I never got a laser that worked (I smashed one and over volted another), so I tried making a 3D printer with a "frostruder" style extruder instead using the same base, but because I tried using my own software instead of something like grbl or teacup, if failed miserably. Now I'm working on a much larger CNC that I plan to (at some point) make a laser attachment for, but I have yet to actually cut anything, so that will be a while.

Sorry to hear that.. The new project sounds awesome, though!

what is RR1A coming out of 5V on the arduino? The symbol looks like a thermistor, but I cannot tell. Also, is SV1 a female header?

Hei guys could anyone tell the list of parts to make the laser module/driver?????

Hi ,

very nice project I have done mine thanks to groover instructions.

More I have fixed the z Axis problem from the homing cycle. modifing the config.h

now hen I use $H the X axis goes on the left far away from motor while if I use X0 goes right. My question is : Do I mirror the inkscape image before use the laserengraver plug in?

BTW this is my calibration:

Grbl 0.8c ['$' for help]

['$H'|'$X' to unlock]

[Caution: Unlocked]

$0=53.333 (x, step/mm)

$1=53.333 (y, step/mm)

$2=53.333 (z, step/mm)

$3=10 (step pulse, usec)

$4=200.000 (default feed, mm/min)

$5=200.000 (default seek, mm/min)

$6=8 (step port invert mask, int:00001000)

$7=25 (step idle delay, msec)

$8=100.000 (acceleration, mm/sec^2)

$9=0.050 (junction deviation, mm)

$10=0.100 (arc, mm/segment)

$11=25 (n-arc correction, int)

$12=3 (n-decimals, int)

$13=0 (report inches, bool)

$14=1 (auto start, bool)

$15=0 (invert step enable, bool)

$16=1 (hard limits, bool)

$17=1 (homing cycle, bool)

$18=69 (homing dir invert mask, int:01000101)

$19=200.000 (homing feed, mm/min)

$20=200.000 (homing seek, mm/min)

$21=100 (homing debounce, msec)

$22=2.000 (homing pull-off, mm)

can you please post your calibration ?

Sir will U help me to make one of this fir mine. I couldn't under stand the circuit so send me the diagrams.and the wearing of the machine.plz help me I want to make I have already collect all the parts but could not mount the boards of driver and arduino board

@biraj1002 if you look at the bottom of this page you will find schematcs pdf file. plz can you remove unecessary comments from page ?

I don't fined it,inkscape also did not proper downloads by the top link

Mr.Groover plz help me to short out the problem. As soon as possible. My email id "birjbhandari.asn@gmail.com". Reply me soon
Sir plz help me I have no idea about circuit, plz send me the close photo of which wire go where. The arduino circuit and the driver circuit motor wire and connecting the both circuit wire, diagrams of circuit and wearing of the boards motors one by one demonstration.I am desperat to make one for my self.plz help me send me the soft were where I can engrave Andy type of photo. I am a student of class 12 so soft were is in my standard how to run the software demonstration.PLZ REPLY ME SOON SIR PLZ PLZ.

Bonsoir mr Groover très belle instuctables j'ai crée le lien à partir du votre la configuration du grbl fonctionne très bien j'ai graver sur le plastique et sur le carton s'est ok mais j'ai essayer de graver sur du bois claire ça ne marche pas même avec du scotch isolant noir .Pouvez vous m expliquer pourquoi ça ne marche pas s'il vous plaît . Le deuxième ventilateur vous l'avez connecter à quel endroit svp en attendant votre réponse merci de nous faire connaître votre savoir .

Hello, I'm excited to start work on my laser engraver this weekend.

I'm just curious if anyone has tried to use this on leather? I got an idea for a leather cuff this morning and I was wondering if this would work to add the design to the leather.

Thanks!
Groover (author)  thakala4 months ago

I did try it on a piece of leather and it did leave a mark. The only problem was that it where a black piece of leather and not that easy to see might work better on tan leather. (engraving pattern, cutting there is no way to weak laser)

thakala Groover3 months ago
Good to know! I'll have to experiment with mine when I finish it.

Unfortunately, this weekend flew by without any chance to work on it. I'm hoping to break open the DVD drives tonight.

Thanks.

Hi! I'm having relay latching problem. I replaced a relay, the transistor, cable. After i put 3 ferite filters on the cable it looked ok, but the latching hapened again. The laser doesent turn on. After i tap on the relay it works aggain for a few times. PLEASE HELP!

Please can somebody provide the circuit for laser shield in pdf format?

Groover (author)  IBH4 months ago

Here is the board, silkscreena and schematic.

IBH Groover4 months ago

Thanks! But to make the circuit I used ratsnest and it said 2 Airwires and I did not understand this?

Groover (author)  IBH4 months ago

Unfortunately I don't know either. There is one place where I used a jumper wire, that might be what is meant? Hopefully someone else knows and can give a proper answer.

IBH Groover4 months ago

Please can you tell me how you made the circuit?And that is the attached circuit correct if made using toner transfer method?

Groover (author)  IBH4 months ago

It looks about right and should work but I have not gone over it in detail. I used a board with photoresist and printed out the trace on overhead paper, exposed in uv light and etched. I have never used the toner transfer method myself.

I have set $0 and $1 to the value you listed, just double checked. So I guess it must be the easy driver. I'll recheck my soldering tomorrow. Thanks for the suggestion.
Once again, great instructable. Really inspired me to make it.
