"Waiting for connection " message

LightBurn Hardware Compatibility NEJE
1

I have Neje Max4, I am running Lightburn 1.4.04. (just upgraded to it.)
I am getting " Waiting for connection " message . Even before I upgraded to new version.
When I run LaserGRBL v5.4.0 I get connection.

What’s the history of this laser? Is this new to you or was it previously working?

Try toggling “Enable DTR signal” in Edit->Device Settings.

Problem solved.
Somehow the comm port got changed in Lightburn .
