Need help with LightBurn software download and install

Software
1

I’m trying to download and install LightBurn for my laser, but I’m confused by the different versions and trial options on the official site. I don’t want to grab the wrong installer or miss any required drivers. Can someone walk me through the correct, safe way to download and set up LightBurn on Windows, and mention any common issues I should watch out for?

Here is the simple path so you do not grab the wrong stuff.

  1. Pick the right installer
    Go to lightburnsoftware dot com, Downloads page.
    • Windows 10/11 64 bit, use the main Windows installer at the top.
    • Windows 7 or old 32 bit, use the 32 bit Windows link.
    • Mac, use the Mac OS DMG.
    • Linux, pick the .run file that matches your distro (usually the regular x86_64).

If your PC is from the last 8–10 years and runs Windows 10 or 11, use the 64 bit one.

  1. Trial vs paid
    The installer is the same for trial and paid.
    Install first, then:
    • For trial, click “Start Trial” on first launch. You get 30 days, full features.
    • For paid, enter the license key you got by email. You can start trial now and enter a key later.

You do not lose anything by starting as a trial.

  1. Pick the right device type in LightBurn
    During first run it asks to add a device.
    • If you have a Ruida, Trocen, AWC controller, pick “Ruida / Trocen / AWC DSP”.
    • If you have an xTool, Sculpfun, Ortur, Atomstack, generic GRBL, or similar, pick GRBL.
    • If your machine came with “LightBurn Bridge” info or looks like a CO2 cabinet, it is often Ruida.
    Check your machine manual for the controller name if you are not sure.

  2. Drivers for USB connection
    This part trips many people.

For Ruida and some others
• Install “CH340” or “FTDI” drivers if the vendor lists them.
• LightBurn has a link to drivers on the download page. For Windows, grab the CH340 driver if your machine uses that chip.
• After driver install, reboot once, then plug the laser in, then launch LightBurn.

For GRBL / diode lasers
Most use CH340 or CP210x.
• If Windows does not see a COM port in Device Manager when you plug the laser, you need the driver.
• Many brand driver links are on the LightBurn download page under “Common USB drivers”.
Install, reboot, then check Device Manager under “Ports (COM & LPT)”. You should see something like “USB-SERIAL CH340 (COM3)”.
In LightBurn, go to “Laser” panel, pick that COM port.

  1. Common installer choices
    • If you are on Windows and not sure about graphics drivers, stick with the default install options. Do not change OpenGL or GPU settings during install.
    • On Mac, drag LightBurn to Applications. First run might be blocked by Gatekeeper. If so, right click LightBurn, pick Open, then allow it.

  2. Quick test that it works
    • Connect USB from PC to laser.
    • Turn the laser on.
    • Start LightBurn.
    • At the bottom right, pick the correct device.
    • Click “Devices”, confirm your laser is listed.
    • If you see “Ready” and no connection error, you are good.

  3. If you want to avoid USB issues
    For Ruida machines with Ethernet port, use a network cable instead of USB.
    • Give the laser an IP in its control panel, for example 10.0.3.3.
    • Set your PC to the same subnet or let your router handle DHCP.
    • In LightBurn, add a new device, type Ruida over Ethernet, enter the IP.
    Network tends to be more stable than USB on long jobs.

  4. Where to get the right info for your exact laser
    • Vendor manual, often has “Controller type” and “USB driver” listed.
    • LightBurn forum has a “Hardware” section with brand-specific guides.
    Search your brand plus “LightBurn setup”, for example “Ortur LightBurn setup”.

If you post your OS, laser brand, and controller name, people can point at the exact download links and driver so you do not guess.

You’re not overthinking it, the LightBurn download page really is kinda noisy the first time you see it.

@cacadordeestrelas already covered the “click here, then here” path pretty well, so I’ll hit the stuff that usually actually causes headaches:

  1. Ignore the DSP / GCode listing on the download page
    The different license types (GCode vs DSP vs Galvo) do not mean different installers. Same installer for all of them. The only thing that matters for you at download time is:
  • Your operating system
  • 32‑bit vs 64‑bit (almost certainly 64‑bit if you’re on modern Windows)

So:

  • Modern Windows 10/11 → use the main Windows 64‑bit installer
  • Only pick the 32‑bit one if you know you’re on a very old machine

You can’t “break” anything by grabbing the wrong LightBurn license at this stage, because you’re not actually choosing that in the installer at all.

  1. Trial stuff in plain english
  • Trial is full fat LightBurn for 30 days. No crippled features, no watermark.
  • You don’t have to decide GCode vs DSP for the trial. You just run it.
  • If later you buy the “wrong” license type (say you buy GCode but your machine is Ruida/DSP), support can switch you, they do it pretty regularly.

So: click installer, install, hit “Start Trial” on first run. You are not locking yourself into anything.

  1. Figure out your controller before you go crazy with drivers
    This is more important than which installer you grab. Check:
  • In your laser’s menu or manual: “Ruida,” “Trocen,” “AWC” = DSP controller
  • “GRBL,” “GRBL-LPC,” “Smoothieware,” “GRBL 1.1” = GCode controller
  • Most cheap diode engravers are GRBL

That controller type matters for:

  • Which license you’ll eventually buy
  • How you connect (USB vs network)
  • Which “Device” you add in LightBurn
  1. Drivers: don’t randomly install everything
    I half‑disagree a bit with the “just grab CH340” idea if you’re not sure. Easier method:
  • Plug the laser in with USB
  • Open Device Manager (Windows)
  • Expand Ports (COM & LPT)

You’ll typically see one of:

  • USB-SERIAL CH340 (COMx) → needs or uses CH340 driver
  • USB Serial Port (COMx) with “FTDI” in properties → FTDI driver
  • Silicon Labs CP210x → CP210x driver

If you plug in the laser and nothing new appears under Ports and nothing in “Other devices” gets a yellow triangle, then yes, go to the LightBurn “Common USB drivers” section and install the likely one for your brand. Vendor manual usually tells you which chip.

Do this order, it avoids clutter:

  1. Laser unplugged

  2. Install specific driver you actually need

  3. Reboot

  4. Plug in laser, confirm new COM port shows up

  5. Mac specifics that trip people up

  • Download DMG, drag LightBurn to Applications
  • First launch might say it’s from an “unidentified developer”
    • Right‑click → Open → confirm
  • For some lasers (especially GRBL diodes) you might still need the same CH340 / CP210x drivers, Mac versions are on the LightBurn driver page or the laser vendor site.
  1. Linux quick sanity notes
  • Use the .run that matches your architecture (normal PCs use the x86_64 one)
  • Make it executable:
    chmod +x ./LightBurn-Linux64.run
./LightBurn-Linux64.run
  • You might need to add your user to the dialout group so LightBurn can access the USB/serial ports.
  1. Immediate post‑install checklist
    Right after install and starting trial:
  • Add device
  • Pick the correct controller family (GRBL vs Ruida/Trocen/AWC)
  • In the Laser window, choose the COM port that appeared when you plugged the machine in
  • If it says “Ready” and the laser reacts to a “Home” or “Get Position,” you’re basically done

If you drop your:

  • OS (Windows/Mac/Linux & version)
  • Laser brand/model
  • What the controller label says (Ruida, GRBL, etc.)

people can point you at the exact installer link and driver name so you don’t need to guess or install a bunch of junk you don’t need.
