To configure your GRBL based board, you need to be connected with LaserWeb or a terminal program.
In LaserWeb, you can send commands manually with the command line on the bottom right of the screen. After typing in the command, you have to press SHIFT-ENTER to send it to GRBL.

Send $$ to get a list of the actual configuration. To set a param you have to send $num=val (ex. $10=0).

Make sure the following values are set:

$10=0      ;send work coordinates in statusReport
$30=1000   ;max. S-value for Laser-PWM
$31=0      ;min. S-value
$32=1      ;Laser Mode on
$100=160   ;steps/mm in X, depending on your pulleys and microsteps
$101=160   ;steps/mm in Y, depending on your pulleys and microsteps
$102=160   ;steps/mm in Z, depending on your pulleys and microsteps
$110=10000 ;max. rate mm/min in X, depending on your system
$111=10000 ;max. rate mm/min in Y, depending on your system
$112=10000 ;max. rate mm/min in Z, depending on your system
$120=1000  ;acceleration mm/s^2 in X, depending on your system
$121=1000  ;acceleration mm/s^2 in Y, depending on your system
$122=300   ;acceleration mm/s^2 in Z, depending on your system
$130=400   ;max. travel mm in X, depending on your system
$131=300   ;max. travel mm in Y, depending on your system
$132=100   ;max. travel mm in Z, depending on your system
$$         ;to check the actual settings
