T2Laser has 3 methods. The more common PWM (pulse width modulation) where the laser is switched on/off quickly similar to how a dimmer switch works for a lamp, velocity mode where the feed rate is changed to alter the burn and dithered which uses a pattern of dots to simulate grey scale. All work well and have their own advantages / disadvantaged, personally I like velocity mode the best.Yes, the firmware I provide is open source Grbl 1.1e/f and the only change is I compile with default settings. You can switch back later.T2Laser supports cutting also, including wood grain compensation and multi-pass with optional cool down and much more. The trial is free so give it a go.
The Nano microcomputer has 8-bit PWM so you can output a value between 0 and 255.0 (zero) means off, 255 means constant on and 127 would be 50% on/off switching. It's how we control the laser power.In T2Laser you can set the min and max levels to anything you like, but the standard firmware is 0-255 so that's what I recommend.
If you want to use 0-1000 for example you can but you also need to change the Grbl parameter $30 to match the setting in T2Laser. It doesn't give you any more resolution or power, it just maps to 0-255 within the firmware.
LightBurn is layout, editing, and control software for your laser cutter. With LightBurn you can:- Import artwork in a variety of common vector graphic and image formats (including AI, PDF, SVG, DXF, PLT, PNG, JPG, GIF, BMP)- Arrange, edit, and even create new vector shapes within the editor, with powerful features like offsetting, boolean operations, welding, and node editing- Apply settings like power, speed, number of passes, cut order, brightness & contrast, dithering mode, and much more- Send the result directly to your laser cutterLightBurn is a native application written for Windows, Mac OS, and Linux. LightBurn talks directly to your laser, without the use of additional software.We currently support most Ruida, Trocen, and GCode based controllers. Supported GCode controllers,include Grbl, Smoothieware, Grbl-LPC, and Marlin. Supported Ruida controllers include the RDC6442G/S, RDC6445G, RDC6332G, RDLC-320A, and R5-DSP. Supported Trocen controllers include the AWC708C, AWC608, and TL-3120.
More controllers will be added soon, so if you don't see yours listed, send us a message - maybe we're already working on it!If your controller is GCode, Ruida, or Trocen based, even if it's not listed it might be supported already - Download the free trial and try it for yourself. If it doesn't work, sometimes it only takes a day or two to make the required changes to support a new board in these existing families.Please note that LightBurn does not support the stock M2-Nano board in the popular K40 laser. This board does not offer control of power through software - we recommend upgrading the board to take full advantage of LightBurn.
NEJE DK-BL AI Laser Engraver - designed for android ios windows - Support NEJE Scanner(android)Dk-bl is a portable device specially designed for mobile engraving scenes. This model has built-in 6000mah lithium-ion polymer battery and Bluetooth module. It can be separated from the computer, relying on mobile phone to realize professional engraving function, and relying on battery supporting 4A output. NEJE DK-8-KZ Laser Engraver - Support NEJE Scanner(android)The NEJE KZ model does not carry a built-in lithium battery. It is powered by a 5V2A charging head.

I made this instructable because I couldn't find software for engraving images with G-code controlled laser. I tried inkscape with extenstions, but this isn't what I expected. I want to engrave photos like attached one, make PCBs etc.@edit: I wont support nor provide old version any longer New one was written in python, can be used on any platform and is opensource! There is precompiled Windows executable in my github repo (link's below).@not longer true: So I wrote app in Matlab, which I use commonly on my university. I call it imGcode I want you to give it a try. It is standalone executable, with all libraries attached, so you will only need to install one file and it should work.You will need laser with grbl or other Gcode controller.
It have to have laser PWM controlled by S code.App is here. App is very simple. You'll have write parameters in command line after app name:python imgcode.py imagepath outputfilepath xoffsetmm yoffsetmm outputimagehorizontalsizemm pixelsizemm feedrate maxpower numberofcolourse.g. Python.imgcode.py lena.png test.nc 0 0 10 0.2 100 255 5e.g. Python.imgcode.py 'C:Documentslaser fileslena.png' 'C:laser filesout filesoutputgcode.nc' 0 0 10 0.2 220 1000 5imagepath - path to image file relative or absolute (most file formats should work, if something fails convert it with MS Paint to bmp or png). I lost it with HDD malfunction.

I was dumb enough to not upload it to cloud or email. Anyway algorithm was like that: Resize image so 1px is minimal CNC step. Set colours to desired levels eg. 16 colors for 16 laser power steps, or binary for BW only. Now zig zag through picture when it's white than M5 G0 to first next black When it's back than M3 G1 to first next white or line ending. And x,y pos in pixels have to be multiplied by CNC minimal step size to get real position.
Minimal step is 0.01mm that picture 10x10mm have to be 1000x1000px and (100,100) position on picture is in reality (1,1)mm which is X1 Y1 in gcode. Thank you for this. I bought a DIY laser like yours a month of so ago and the software that came with it is very basic and limited. What I want is photos like your example but no luck so far.
When I set up a file using Photoshop the laser software takes liberties with it and it turns out most black and white with little to no shading in between. I am getting closer by using 'lasergrbl', which is a lot nicer for photos but still tweaking. This laser was so inexpensive so I do not want to buy software that at best will cost $40 or one third the cost of the machine. I tested 'T2Laser' and think this might just be the premium photo engraving software but they are cheap with their demo. It only runs for 30 minutes and allows a limit on how many lines it will burn down while testing so not enough time to see results. In a passion, after thinking I was getting good results, I tried to buy the full version of this software but they only accept PayPal, which I have no luck using from where I work near Hong Kong so I was stopped cold.
Where can be my problem? I run Windows 7 in KVM and it's extremely slow.
I already could write a book with what I have learned but none of it has yet yielded acceptable results. Now I am starting to consider upgrading to a small Chinese Co2 laser with 40 or 50 watts as they are more versatile in terms of photo burning, especially on acrylic, which our diode lasers will not work very well. It was photos and acrylic that got me interested and these are not working so well with a 6.5 watt diode. Springfield halloween 2013 donut hack. I will try your software and let you know how it comopares to what I have tried so far.
