Problem with A NEJE Master 2 the power of the laser 20W is not 100%!

Hi !

I have a Problem to cum upp in 100% Power with my 20W laser for my NEJE Master 2, what is the right value of the Parameter $30 in the GBRL ? is it 255 or 1000 ?
When the Power value is 100%, the laser is almost off, but if i set the value to 50% then the laser is mutch more Power in, up to about 60% then if i set it higer the Power will go off…

My $30=255 is this right or shuld it be 1000 ???

Any one that has cheked this out ?
Best regards
