hola a todos, he estado recopilando información y no encuentro en ningún lado los software necesarios, algún lugar desde donde recibirlos? Saludos a todos

Подскажите пожалуйста. Нашел вот такие двигатели Nema 17 34mm 12V 26Ncm(36.8oz.in) 42SHD0001. Но они есть на ток 0,4А и 1,5А. Какие лучше сюда установить?

the link Grbl Controller 3.0 by Zapmaker http://zapmaker.org/projects/grbl-controller-3-0/

has been dead for a long while can you provide alternative path ..

have you tried to cut even pcb?

4k to 10k standard resistor

Hi! What is volume of resistor in TTL?

BOM - bill of materials has been updated!
Wiring Diagram added.

All 3D printed Part files has been updated to version 2.0

GRBL0.9i_Library_zelosLaserengraverV2.zip has been added to the Instructions. GREAT to see another build from another person :)

modified GRBL library for the Arduino IDE will be available very soon.
almost a complete update of the Printed Parts.
2 . Generation is ready to come out ;)

I have complety build ,but I have problems which software and firmware you use and how Laser driver you use.
Can you send me some links ?


Hi dear friend,
Can you upload your complete config arduino ?

Thx :)

Please never forget that the laser can cause serious damage to your eyes. always wear safety glasses!!! Avoid to look directly into the beam.

are you relying on goggles for eye protection?

Take a look: http://3dprintzothar.blogspot.com/2014/08/40-watt-chinese-co2-laser-upgrade-with.html

i hope this will help. there is all what you need. plugins,firmware,BOM and more.

I'm trying to build a CNC Laser Machine and I want to use CO2 laser to cutter acrilic, wood and metal sheets.
I want to know if can I use arduino to control the CO2 lasers? My CO2 laser cutter may be like yours.
Thank you.

currently we are working on the Electronics Case Design.
keep looking from time to time ;)

that would work but you need a different firmware version of GRBL and a different wiring for the Mega2650 Board!

Where can i find that?


If any have problems with getting/pay for the aluminium profiles, then take a look at these http://www.thingiverse.com/thing:800597. I have used them in other projekts and they are ouite stable.

Printable Extrusion Kit

Hey vandborg!

What have you used them for? I am really interested to see people using it the extrusion.


What do you mean?
"2x - handles"

If you are interested in high-quality and low-cost aluminum profiles, I recommend this seller. Cut exactly to the mm.

The total price of a kit is about 350 €. (High Quality/high precision)

depending on which material you use to print the parts, what quality of screws etc

have a nice day

Hey Coffemaster,

Of course I'm going to upload the wiring diagram. I just need to find time to do it: P

The Pololu a4988 Stepper Driver can you find too on Aliexpress from the same seller as your Motors:http://www.aliexpress.com/store/product/10pcs-lot-Reprap-Stepper-Driver-A4988-stepper-motor-driver-10pcs-heat-sink-with-sticker-free-shipping/1494743_32230923668.html

The Motors will works without problems.

If you have any further questions, you can ask me. no problem. I'm happy to help.

have a nice day

Thank´s for your fast reply. Do you have no idea the total cost of this project?

And how much will it cost and where can i find the Aluminium profiles 20x20 Type B?

Hey Coffemaster,
very soon we will start our Kickstarter campaign. There you can buy a early bird complete kit.
but if you're searching just about the GRBL Shield, here:http://www.aliexpress.com/item/3D-Printer-CNC-Shield-for-Arduino-GRBL-Compatible/1931530630.html
have a nice day

Thank´s for very fast reply. Will you upload a wiring diagram so i know how to wire everything? Where can i find the "Pololu a4988 Stepper Driver" And Will this stepper motor work? http://bit.ly/1H3PyPB Sorry for so much questions...

Comments deleted.

Where can i buy a GRBL-Shield?

It is me a pleasure :)
you are welcome

Thank you, already placed order :)

hey james_III,
This Project is still in process but i do my best.

for now i use this:http://www.aliexpress.com/store/product/300mw-purple-Laser-Module-mini-Laser-engraving-machine-laser-cnc-parts/922826_1976917790.html

Wavelength: 405nm (purple laser)
Optical power: real 300 mW

I use it at 250mw over a year and the diode still working fine.

but i try to upgrade it to a 2 watt M140 Laser Diode with a big driver.

i will add a LCD with SD card support to the Version 2.0
Thanks for your comment.

have a nice day

Can you be more specific about 250mw laser module
Where to get one?
What power driver?
Lenses? or is this really ready module?
Lastly how long this 250mW laser module last before new is needed?
I suggest to use some sort of display and SD card module, so there is no need for computer.
