RDWorks vs LightBurn for CO2 Lasers
RDWorks is the free Windows software that comes with Ruida-controlled CO2 lasers; LightBurn is paid software, with a 30-day trial, that also drives Ruida controllers and works on Windows, macOS and Linux. Choose RDWorks if free and basic is enough; choose LightBurn for a more modern interface, a material library and cross-platform use.
You open the CD, USB stick or download link that came with your new CO2 laser and find RDWorks. It works, but it feels like software from another decade. Then someone on a forum says LightBurn changed their life. Is it worth it?
RDWorks is the Windows software from the Ruida controller ecosystem, usually supplied with the machine. LightBurn is a third-party program that supports Ruida, Trocen, TopWisdom and GRBL-type controllers. Both can drive many Ruida-based CO2 lasers.
Comparison
| Point | RDWorks | LightBurn |
|---|---|---|
| Price | Normally supplied with the machine | Paid, 30-day free trial |
| Platforms | Windows | Windows, macOS, Linux |
| Typical imports | DXF, AI, PLT, images; SVG in newer versions (check your version) | SVG, DXF, AI, PDF, PLT, images |
| Layers | Color layers with speed and power | Color layers plus modes, passes, material library |
| Interface | Older, dense | Modern, more visual |
| Machine support | Ruida-based machines | Ruida, Trocen, TopWisdom, GRBL and others |
| Camera, jobs, frame | Basic framing | Frame, camera and many helpers |
Versions differ, so confirm in each program's import dialog.
Factors
- Operating system. On Mac or Linux, RDWorks is not an option.
- File formats. If you work mostly in SVG, LightBurn is smoother; DXF imports in RDWorks can need care with units and settings.
- Budget. RDWorks costs nothing extra; LightBurn needs a DSP-type license.
- Saved settings. LightBurn's material library speeds repeat jobs.
- Risk. Test LightBurn on your controller during the 30-day trial before you buy.
Pro tip: Export your RDWorks settings table (speed and power for each material) into a note before switching. You will need the numbers as a starting point in the new program.
Worked example
For 100 W CO2 cutting 3 mm plywood, a starting point might be about 40–70 mm/s at 55–75% power, tuned on scrap. In either program you set that on a CUT layer. The difference shows up on Monday morning: LightBurn recalls "3 mm ply, air on" in two clicks, while in RDWorks you retype or reopen an older file.
Common mistake: buying a LightBurn license for the wrong controller type. Ruida needs the DSP-type license, not the GCode one. Confirm before you pay.
Whichever you pick, learn the basics of layers once. The idea that each color is a job with its own speed and power carries across every laser program you will ever use, which is why a short evening spent on cut, engrave and score layers pays off for years.
What changes when you switch
| Item | What to carry over | What to redo |
|---|---|---|
| Design files | SVG and DXF open in both | Check scale after import |
| Speed and power numbers | Use as a starting point | Re-test on scrap |
| Machine setup | Nothing | Add device, set bed size and origin |
| Layer habits | Same idea: one color per job | Assign modes again |
Switching programs does not change the physics. A 100 W CO2 laser still needs about the same energy to cut 3 mm plywood, so your old numbers get you close and a quick test gets you the rest. Give yourself an afternoon, a few scrap squares and a cup of something warm, and the new interface will stop feeling strange.
