have you checked if the beam got out of focus?

I just got my Uarm but when I tried to engrave some shapes laser didn’t work. Blue laser light turns on and it follows the pattern but doesn’t burn. What is wrong with it???

Hard to tell, have you checked the focus setting like its written in the quick start guide??
