Hi John,
As mentioned in my previous post – you need the PWM on one pin and the switching signal (M11/M10) on another pin. The PWM is variable by the S### word and turned on by the M3 command.
In operation the PWM is turned ON and left running. It is then applied to your laser TTL input by the gated PWM/M11/M10 signal so you need to construct a small circuit (as I described in my previous post) to achieve this. At the end of the job the PWM is turned OFF by the M5 command.
