im using gbrl 1.1f with lasergbrl.

Check your spelling. I doubt that that is what you are using.

ok gbrl if it makes you happy.

Check out this page for information on connecting the laser and configuring lasergrbl for PWM control of the laser.

The acronym is GRBL.

Is your laser PWM controllable? Not all laser modules/power supplies are...

I've never used GRBL.

I don't know what "find" means but you can easily generate PWM with [u]analogWrite()[/u].

the laser has power to the driver switched via a mosfet which is in turn switched by the arduino so yes it should be pwm ready,it works as is but is just on or off,no pwm.
