MeerK40t (pronounced MeerKat) is a built-from-the-ground-up MIT licensed open-source laser cutting software.
The primary goals of this software is simple:
- Provide users with high quality laser control software.
- Provide developers with a highly extensible platform to help further their own ideas, and provide novel work to the laser community at large.
To get up and running, simply download Meerk40t from here for your specific platform. (Windows, Mac OSX, Linux, and by extension, Raspberry Pi).
Release Versions (Just use the latest)
- 0.9 - Active - New features and some underlying architectural changes. Try the latest released version: 0.9.4
- 0.8 - Maintenance - may receive critical bugfixes but no more new features, latest version: 0.8.12 (Oct 17, 2023)
- 0.7 - Discontinued - K40 support only (including ruidacontrol emulator for 3rd party lasersoftware integration), latest version 0.7.10 (June 13, 2023)
- 0.6 - Discontinued - K40 support only, latest version: 0.6.24 (Oct 11, 2021)
Meerk40t has an advanced internal console system allowing access to most parts of the code with various commands. It also provides a command line interface which should allow you to automate any processes. To learn more, download a version of Meerk40t for your platform, and execute it in a terminal with the --help argument to get a list of options.
Alternatively you can run MeerK40t directly from Python. pip install meerk40t[all] with python installed will usually be sufficient. Then merely run meerk40t at the command line.
The wxMeerK40t is the GUI and is written in wxPython. We use AUI to allow to have a very highly configurable UI. We can easily add panes and tools and there are quite a few available already.
Meerk40t provides a variety of drivers with an extensible framework to provide support for other new laser devices. The code was written with the myriad of possibilities for different software in mind. For example, it may be essential that GRBL be able to reset an alarm or notify the user of particular error codes. The configuration for GRBL is not the same for the configuration of other laser control drivers. With this in mind, Meerk40t can radically change how and when it works
- Lihuiyu M2/M3-Nano
- Any GRBL device (Longer, Creality, etc...)
- Ezcad2-compatible JCZ controllers galvo lasers
- Moshiboard
- NewlyDraw System 8.1 Lasers
- Ruida-Emulation (Middleman between Lightburn and K40)
More device support info
For the Lihuiyu (stock driver), Meerk40t supports both the windows and libusb connection methods, making it compatible with Whisperer and with the original Chinese software. So MeerK40t can usually run alongside these other pieces of software interchangeably.
GRBL is itself open source and the various interfaces with the board should be quite well understood.
Meerk40t supports controlling galvo as well as gantry lasers with open source support.
The support for old moshiboards makes meerk40t the only known opensource software that controls moshiboards.
HPGL-modified laser systems produced under many different company names

Open source projects live and die with their support. There are a lots of ways to help the project. There are also a lot of ways the project should help you.
- Code
- Provide Translations in other languages.
- Design ( Good design instincts, smooth out the rough edges)
- Compile/Testers
- Beta testers
- Make helpful support content
- Make guides ("How to set up cameras?", etc.)
- Bounce ideas around

Meerk40t allows to act as an intermediary between your K40 laser and software that supports Ruida-controlled laser equipment - Lightburn is a relevant example of such a software product. You just need to issue the command ruidacontrol in MeerK40ts console window, and you will then be able to add an emulated Ruida Laser inside Lightburn™. Laser jobs that are created inside Lightburn™ and sent to this laser will be picked up by MeerK40t and sent to your K40. See some more detailed instructions in this video. Please note ruidacontrol will require the DSP version of Lightburn™. (Present in all versions since 0.7)
With 0.9 another way of interacting with Lightburn was introduced, which will work as well with the standard version of LB: You just need to issue the command grblcontrol in MeerK40ts console window, and you will then be able to add an emulated remote GBRL-LPC laser inside Lightburn or any TCP GRBL control software.
