How to wire 2.8 jtech laser with quiet cut spindle

Spoke with Griffin @ inventables yesterday.
It seems that my speed control is unable to handle the PWM signal from pin 11 or it has gone wonky
I have ordered a pcb that has a larger MOFSET to handle the PWM signal per his suggestion.

Apparently this will eliminate the speed control altogether.

SUCCESS!
Or at least halfway there.
I installed the pcb interface to my 48 watt power supply Made the connections and I now have PWm spindle control!

Now to move on to getting the little flashy thing to light something on fire!
