Void Micro LC1720T will not connect

I am new to laser engraving and have been trying to get LB to discover my Void Micro LC1720T but it will not connect.
Any help would be appreciated.

This is my first time hearing of this machine or brand. I Googled, and found only their website which references the machine and provides a picture. It looks like a Neje clone.

The documentation on their site talks about the firmware switch required. I would recommend starting there.
