    Default AWC708C LITE controller does not output PWM signal on either Laser 1 or Laser 2 port

    New to forum today, have AWC708C LITE controller on generic Chineese cutter / engraver. The laser tube and HV power supply work (laser emits and burns target) when HV supply is jumpered for test but does not fire when connected to AWC708C LITE controller either with "Laser" button or when running test program / CAD drawing. Upon testing with DVM I get no / 0 volts at the PWM output pins of either Laser 1 port or Laser 2 port on the controller. What could be inhibiting those ports? OR do I possibly have dead output drivers on both? OR (most likely) am I overlooking required parameter or configuration settings? I have looked for and tried to properly set or inhibit the obvious ones to this point.
    Thanks for any help!

    Check for a door switch or water flow switch open. That will keep it from firing. I have my top door switch button permanently taped for that reason.
