Neje Master 2 on Fedora 34 low power to laser module

I have Neje Master 2 and I’m Using Fedora 34, I have setup the LightBurn with GRBL manually.
My issue is when I start the printing, Laser just plays as it is printing without sending enough power to laser module, as I click on Frame icon It actually starts to cut due.
I also set the laser power to 100% but i’s not doing anything.
to check my laser engraver I have checked with my android tablet and phone and it cuts with no issue.
did I change any value by mistake ?
thanks for anyhelp

check the value on the green circle is equal to $30 in the firmware
