Lightburn will not connect to my boss hp machine

Boss laser hp3655 lightburn wont connect

I assume you have installed drivers and gone thru device set up in Lightburn.

Hi James,

How are you connecting to your laser physically? USB or Ethernet? If you can go as far as explaining from port to port what is inbetween your PC and Laser that would be ideal. USB extenders and Hubs are known to cause problems, as will directly connecting ethernet to your laser controller without proper configuration.

As the poster above noted, it’s important to install DSP device drivers to communicate with your particular laser. If you’re not sure you installed them the first time around, re-open the LightBurn installer and select ‘Install DSP drivers’ in the final installation process page.
