@PeterT: I think Vicious has the same driver and noted the same issues with the light never turning off. The light turning off is nice because it indicates the current level is low enough to connect the laser diode for current adjustment without risk of burning it out. If your light does not turn off then just set the voltage to 6.5V as described in the guide and turn the current adjust screw counterclockwise a good 4 or 5 full turns. This should be enough to ensure the current is low enough for safe diode tuning.

You can’t get over .7 amps? Which step are you at here? Is the diode already connected and you’re doing the current tuning?
