GRBL v0.9j and older, if GRBL setting "$30" (Maximum spindle speed / RPM) can't be altered.
■ G-Value Max
GRBL v0.9j and older does not have the ability to change the set Spindle PWM range.
There are also some cases, like when your spindle is controlled by this value, and need
to be set in software.
Because of this we will have to change a setting in LightBurn.
