LE5040 lsaer engraver not responding

Newbie to CNC laser engraving. recently bought a Genmitsu LE5040 Laser Engraver. Got it together and dbl checked everything. Installed new driver and Lightburn. Verified USB port in device manager. Have GRBL as device, set S-value and baud rate correctly. Console says I’m connected. Will stream data to machine but it’s never even moved. Laser will fire from control board switch but that’s it. Could it be possible I have a bad control board? Appreciate anyones help

when it opens it says this;
Waiting for connection…

Grbl 1.1f [’$’ for help]
