There are 3 ways to connect your LightBurn USB camera to your computer. You can use existing factory USB serial cables inside your Thunder Laser by adding some additional components. You can also simply run the USB camera directly to your computer. These methods are listed, in order of performance and reliability, below:

NOTE: the USB cable carries a HUGE amount of data, so any extender used must be an active amplifying USB 2.0 rated cable.

The LightBurn camera is completely independent from the laser. The camera ultimately connects directly to your computer. The camera does not connect to, nor is it dependant on the DSP controller.


1. Our recommended method is to install a powered and filtered USB hub. This hub will connect to the USB cable in the Thunder laser and then the DSP controller and the LightBurn camera will connect to the hub. It will mount in the right front electronics bay and get power from the factory power busses. Here is the link for the commercial USB hub. The hub we selected can be powered by 24VDC. Thunder Laser machines have a few wiring variations so it is imperative that you pull 24VDC from the correct source. Here is one of the industrial powered hubs mounted in a Nova 35-80.


2. Another way to connect to the OEM wiring is to connect your DSP controller via ethernet, then you only need a USB B female to a USB A female adapter like this one to connect the camera directly to the PC cable. This will remove the DSP controller from the USB connection altogether and the USB will carry only the camera.

3. And finally, you could run the LightBurn camera directly to your computer without interfacing the Thunder Laser systems at all.

IMPORTANT NOTE: The USB cable provided with your Thunder Laser is quite long and adding additional components, adapters, terminations, etc… can cause a multitude of issues. USB serial data is very susceptible to noise, interference, etc… and can affect performance. You should use high quality shielded USB wiring components and keep them as short as possible to help avoid signal loss and corruption.
