I have a brand new Sculpfun S9 and a Hewlett Packard laptop computer, running Windows 10.
Lightburn ( trial version ), does not find the S9 when using Find Device is used.
How can I remedy this
You can click on create manually, and enter the information.
As mentioned, add the laser manually. The procedure and recommended parameters for an S9 are described here: Setting up the software – Diode Laser Wiki
