# Hau Tian RF CO2 Galvo Laser

This is a **Hao Tian 40W RF CO₂ Galvo Laser**—air-cooled, lightning fast, and running **LightBurn** exclusively. We’ve got this set up in the shop now, and a go-to for engraving projects where speed and clean detail actually matter.

If you're new to galvos, the main difference is how the beam moves—no gantry or belts, just a pair of high-speed mirrors that throw the laser around with insane precision. The 40W RF tube is metal (not glass), so it fires instantly, stays crisp, and doesn’t need constant fiddling. It’s air-cooled too—no chiller, no drama.

This setup shines on wood, acrylic, leather, and plastics. Perfect for marking QR codes, logos, labels, or just batch engraving with a fast turnaround. You’re not cutting through thick materials with it, but for engraving its the machine.

And yeah—running this on **LightBurn**. The interface is clean and no EZCAD headaches.

## Downloads

Don't trust that malware or something "fun" isn't on that included USB drive... yeah I don't trust them either.  These are the EZCAD markcfg7 configs pulled from the USB for the Galvo lenses.  These will be handy when setting up device profiles in LightBurn.
