Laser does not turn off during travel to next burn. PWM Marlin G-code Maker Select Plus

I have searched through post and have only found information for GRLB another firmware I believe.
In G-Code m106 S0 is not working. It works on command line
1/19/2021- I hooked up a led strip to the PWM Fan output. It appears to be sending a signal to turn power off. So the either the duration if being off is not adequate or speed of travel to quick. Getting beyond my level of experience. I will keep digging any help would be appreciated.!
