Hit a snag.
The laser has a simple red and black two wire connector.
The laser socket on the board has three connectors.

What's the third one for and if I stick the two wires onto a three pin connector, which pins do i stick which one on ?

Is there anywhere I can get an actual manual for the: Bt 7200V 1.8.26 Ramps plus 2 board ?

I'm hitting a complete blank on internet searches.
Ramps 1.4.2 exists but not 1.8 or plus 2 boards.

I know it exists, I've got one and so far I'm pretty impressed by it.
But a manual would be pretty useful, or even just the pin-outs for the laser connector :-)
