Timer Setup and PWM

-

hello everyone,

first off, thank taking time me question.

my question this:

would possible increase resolution of pwm on pin 11 of arduino nano 256 2048? i'm using grbl control small 40w laser engraver built , 256 power levels not enough clear gray-scale color differences. have been looking around @ how manipulate timers , such on arduino since competent c++ programmer have gotten more confused start.
