I am new to this hobby and purchased a used Sh-g350 laser enngraver. The mirrors need alignment but the laser button on the control panel does not fire the laser. I get the beep when the button is pressed, and I see a brief flash in the laser tube, but no laser output. If i start a cut or engrave job, however, the laser works, it's just out of alignment. I can't really align it without having the pulse. Has anyone here seen this issue or have suggestions?
Thanks
