Original Parts and Wiring

Before dismantling my K40 for Smoothie upgrade, I write down here the original state (stock) for memory and sharing.
Wiring specifications on photos comments.

how will you control the laser power now ? is it done with the X5 ? or do you still plan to use the panel mount POT ?

I know that the X5 will have a PWM output for the laser but I wonder if the PWM works on the same input as the POT V-control 0-5V
