SKR PRO v1.2 + NEJE TTL Laser

@robertbu, take a look at my new summary post:

Like you I wanted to isolate the power pull from the Laser so it’s not being drawn through the board. I use an SSR (Solid State Relay) to switch the power directly from the Power Supply using the SKR as the Control. I bought mine 2 for $10 for another project, but I see equivalent ones for $8-10 for one these days.
