If GRBL changes are not saved it’s because the manufacturer of your laser has prevented this in their firmware. You could ask your manufacturer if they provide alternative firmware that allows writing changes.

Or else you could potentially upgrade your own firmware. It looks like your laser manufacturer uses Arduino based controllers which could be easily flashed with your own firmware. However, there is a risk of bricking your controller if things don’t go well and you don’t have access to the original firmware.

my firmware is grbl1.1f benbox

problem solved flash firmware to GRBL 1.1h
