Old thread this I know, but has anyone on the forum with one of the Chinese generic laser engraver / cutters done any tweaking of the laser tube current, and if so care to share their experiences ?
I've relatively recently got a supposedly 60 watt 500 mm x 700 mm version. It works but I reckon it's down on power. I've been through the alignment but my cutting rate seems down on what comparisons I've been able to glean from Googling.
There is at least one YouTube video showing someone setting the laser current, but his set up seemed rather lethal to me
