And I am not seeing a third marked pin on mine. There is one port for analogue, CN3, but that's not what we want.

Munchit1,
Sorry for the late response. As to the simplify 3d thing, I highly prefer LaserWeb or just about ANY software that is actually made for lasers. It is much more customizeable and has many options. It's just a matter of generating Gcode.
I understand the PWM SXXX commands (XXX symbolizes your laser intensity). The issue is with all the drivers I use, the laser appears to just be always on. I can ground the positive TTL input to turn it off but it inverts the commands and suddenly M106 means off. Not to mention PWM goes out the window. There must be something simple I am missing but I don't see it.
