No laser on my Em-Smart

EM-Smart received this morning. After 2 minutes of good testing, the laser no longer marks. EZCAD works as if the marking was done. The laser makes the engraving delimitation (F1), operational red light. I run the marking which is taken into account by EZCAD but on the other hand, nothing happens on the machine.
Pulse power on 50 %, speed 1500 or 2000
I try on a second laptop, new install and it’s same incident. No shoot.
HELP PLEASE
