I have had a new machine and laser need some help setting it up ortur master 2 pr s2

There are a number of previous posts on this. Here’s one:

Windows 10 should ship with the drivers necessary for communicating with that laser. You should see a COM port assigned to the laser in Device Manager. If not, then a driver may need to be installed.

However, you still need to create a new device for your laser in LightBurn. Push the Devices button in Laser window and try “Find My Laser”. If that doesn’t work you can create the device manually.
