problem with laser operation

[Markliniste]

Hello, I am having a problem with Laserweb.
I create my cutting piece, I enter the values of my machine and I generate the GCode, it is ok to create. At the time of cutting, my machine starts and follows the contour of the part, but the laser does not turn on, even when "Laser On" is indicated in the macros. Do you know how to solve this problem. My laser works.
I own a Sculpfun S30 and I can cut pieces with LaserGrbl.
Greetings
