Laser not firing on laser test switch

Hello all, i have installed my C3D with Smoothieware. In lightburn, I can jog, and when I run a job, the head is moving ok, but the laser does not fire. I have set my power on the k40 to 25%. If I press the laser test switch on the control panel, the laser does not fire. However, if I press the switch on the power supply, the laser does fire, and the amp meter reads about 12 mA. Can you help? thanks. Paul

Do you mean the physical button on your machine? In a normal situation your test butten is connected parallel with your C3D laser output. Can you trace the Laser FIRE and laser GND back to the power supply?

Does the red laser fire led in the left bottom corner blink when you run a program?

solved thank you
