#define SPINDLEPWMMAX_VALUE 1024.0 // Translates to about 1.9 kHz PWM frequency at 1/8 prescaler

any reason why the default grbl-mega using 1.9khz while grbl just using 1khz and most chinese laser compatible with 1khz?

Hi @ariefadha,

No, there is no particular reason…
This was the default from the gnea/grbl-Mega version which I used as a starting point for grbl-Mega-5X.
