@Lloyd-downunder Gyday mate.
well in a couple of breaks from the other wiring, I was doing , got to use the meter on the board to no avail? your stat said,(This wire is the TTL control. Connecting it temporarily to the 0v should turn the laser off,).
OK this board is available from BG and others, there will be others that want instruction too. so u see its not only me got it.
iam not a Nerd, but a Turd, get the shits with things that don't work out!
am not alone! look at the forum.
