I have a 130w tube and the max current is 30ma- which means that I am running at 45% power most of the time- with maybe a quick sprint to 50% (32ma) now and then (never been good with rules:nono. Somewhere I 'thought' I saw a laser attenuation setting but I can't put my finger on it right now. Anyway... it would be great to be able to 'hobble' the laser output so I would have a larger range of power settings. Is that possible or am I jousting at windmills yet again in my old age? Maybe turning down the laser power supply or ?. Thanks for any thoughts you might have. Gene
