Thanks for the advice guys, i did notice that the laser went from an extremely bright beam to sod all, i was worried that the diode had died. But after a quick recharge it was back to full power.... Phew!
I will post some pics of it when i get back from work ;)
Finally completed my c6 build. M140 diode and moh driver at 1.62A no idea what power it is but it is insane! MUCH more powerful than my green laser. I just have a question. The diode and driver is heat sinked but the laser gets quite warm after about 30 secs, is this normal?
