Console fails to connect

The laser window states laser is ready. The console window is waiting for connection.
Have tried many times to set up the Z1, with no luck.
When using the Laser GRBL software, it works. Just not for Lightburn.

If LaserGRBL is running and using the USB port, the computer denies access to that USB port for LightBurn or anything else. Close LaserGRBL and then launch LightBurn. Wait a minute or so and see if the Console window shows a connection message.

The driver is installed, so we can skip that formality.

Comgrow wants a really high Baud rate in their LightBurn set up docs.
It worked for me.
