I have purchased the AWC-708C DSP controller and have set it up as per the smoothie site, Problem can not get the laser to fire. On the power supply the IN pin is driven the smoothie PWM which per my scope is working but no firing. When I press the fire test button laser fires, and ALSO when I take TL to ground also the laser fires.
Can any one tell me if I need to use the PWM pin only or use the PWM + TL together ie using the TL as an enable pin.. If I need to drive both the PWM + TL what pin on smoothie do I use?
The new AWC708 is same as the 608 for all practical purposes .
