Well, got my first laser PSU shock. Not too terrible, but it is really annoying, loud and it makes you jump.
I had my laser and PSU test firing from the bench last week. Now I am ready to put it in the 2.x and it is not firing.
I have the 40w PSU that has the test button on it. When I hit the button, it makes a buzzing electrical noise, lights up 3 lights on it, but does not fire the tube. I am going to rewire the positive and negative connections on the laser and try it again.
This is what happened:
I unplugged it, pushed the test button several times and waited about 10 mins before disconnecting the positive screw connector (the big white one.) When I started unscrewing it, I got one of those 1 inch spark shocks.
I changed some wires, tested it again and then went through the same test / wait 15 mins, and it still hot. The second time I disconnected it with something insulating. The spark then jumped to the metal frame nearby.
Any ideas on how I can get rid of the charge on this thing so that I can work on it? I would rather not shock myself each time.
Thanks...
