LightBurn vs. LaserGRBL: Which Laser Software Should You Choose?

If you have just got your laser engraving machine and you are spending some time in the laser engraving community, you've likely run into the LightBurn vs. LaserGRBL debate. The short answer: LightBurn is widely considered the superior option. It's an essential, all-in-one upgrade for multi-layered projects and efficient workflows, and most experienced engravers eventually make the switch.

That said, LightBurn isn't free. It carries a one-time cost of roughly $60 to $100 depending on the version, and it comes with a steeper learning curve: something that matters if you're just starting or working with a tight budget. LaserGRBL, on the other hand, costs nothing and gets the job done for simpler projects.

So rather than assuming one is automatically "better" for you, it's worth understanding exactly where the two programs differ so you can decide whether LaserGRBL fits your workflow or it's better to upgrade to LightBurn.

Key Differences Between LightBurn and LaserGRBL

The differences between the two programs are most apparent across four main areas: cost and compatibility, workflow and design, features and control, and advanced tooling.

1. Cost and Compatibility

• LaserGRBL: 100% free and open-source, but strictly runs on Windows.
• LightBurn: Offers a 30-day free trial, after which it requires a paid license (usually around $60 for G-code lasers). It runs natively on Windows, Mac, and Linux.

In short, LaserGRBL is free but limited to a single operating system, while LightBurn costs money but works smoothly across all major platforms.

2. Workflow and Design

• LaserGRBL: Functions purely as a control and streaming tool. All of your image prep and vector design needs to happen in a separate program, like Inkscape, before you load the file.
• LightBurn: An all-in-one design and control suite. You can draw, trace, add text, and set up layered burns within the same application, with no exporting back and forth between programs.

3. Features and Control

• LaserGRBL: Best suited to simple burns. You essentially set one speed and one power level for the entire job.
• LightBurn: Allows fine-tuning of every detail. You can run layered burns in a single session (for example, lightly engraving an image, deeply engraving text, and then cutting out the shape), use material libraries, and auto-generate complex G-code on the fly.

4. Advanced Tools

Beyond the basics, LightBurn also offers advanced tools that LaserGRBL simply doesn't have: camera integration for precise placement, automatic test grids for dialing in settings, and expanding material libraries. LaserGRBL, by contrast, sticks to manual framing and a handful of basic custom buttons.

Using LightBurn vs. Using LaserGRBL: 4 Practical Differences

1. Layered Jobs vs. Single Actions

In LaserGRBL, you set one speed and one power level per run. If you want to engrave a photo and then cut an outline, you have to manually align and load two separate files. In LightBurn, the process is far smoother: the software uses color-coded layers to run complex engraving, shading, and cutting in a single button press.

2. Built-In Design Interface

LaserGRBL requires you to prep all artwork externally,  in Inkscape or Adobe Illustrator, for example, before loading it in. LightBurn features fully functional CAD tools built into the program itself, meaning you can design on the fly without switching applications.

3. Time Savings

For many users, the time saved by LightBurn's smoother interface is the biggest justification for its cost. LaserGRBL's interface is comparatively basic, which often means more double-clicking and more waiting for items to load, a frustration that adds up quickly and is a major turn-off for a lot of engravers, myself included.

Which One Should You Pick?

Choose LaserGRBL if:

• You have a strict $0 budget.
• You only plan to run straightforward image engravings.
• You're completely fine importing finished designs from separate software.

Choose LightBurn if:

• You want to save time.
• You're creating multi-step projects.
• You want convenient helper tools, like a material library.
• You need to run your laser machine natively on a Mac or Linux machine.

If you're still unsure, take advantage of LightBurn's 30-day free trial to see whether it fits your workflow before committing to the purchase.

How to Set Up a 30-Day Free Trial of LightBurn on an OMTech Pronto 60W

To set up your 30-day free trial of LightBurn with an OMTech Pronto 60W CO2 laser, you'll need to download the trial and manually pair it with the machine's Ruida digital controller. Here's how:

Step 1: Download and Activate the Trial

1. Go to the official LightBurn Download / Trial page and download the version corresponding to your operating system (Windows or Mac).
2. Run the installer. On Windows, make sure to check the box to install the FTDI serial driver; this allows your computer to communicate with the laser controller.
3. Open LightBurn for the first time. When the license prompt appears, click Activate Trial. This unlocks the fully-featured software with no watermarks for 30 days.

Step 2: Connect the Hardware

1. Connect your OMTech Pronto to your computer using the provided USB cable.
2. Power on your water chiller and exhaust fan, then switch on the laser machine itself.

Step 3: Configure Your Pronto 60W in LightBurn

CO2 lasers don't always auto-detect over USB, so you'll want to configure the machine manually:

1. In LightBurn, look at the Laser window in the bottom right and click Devices.
2. Click Create Manually.
3. Select Ruida as your controller type and click Next.
4. Choose Serial/USB as your connection method.
5. Name your machine (e.g., "OMTech Pronto 60W").
6. Enter the work area dimensions. For the standard Pronto 60W, enter 700 mm for the X-Axis and 500 mm for the Y-Axis (approximately 28" x 20").
7. Set the Origin (homing position) to Rear Right, which is typical for OMTech Ruida machines.
8. Click Finish.

Your machine status in the bottom right corner should now change from "Disconnected" to "Ready."

Final Thoughts on the Differences Between LightBurn and LaserGRBL

Both programs have their place. LaserGRBL is a genuinely useful, zero-cost tool for anyone running simple, single-layer engravings on a Windows machine,  and there's no shame in sticking with it if that covers your needs. 

But if you're working on multi-layered projects, want a smoother design-to-burn workflow, or need to run your laser on a Mac or Linux system, LightBurn's added capability quickly pays for itself in time saved. If you're on the fence, the 30-day free trial is the easiest way to find out which side of that line you fall on.
