Hi all,
I need a bit of help troubleshooting my ULS 3.50.
Last Tuesday I made some aluminum business cards with no problems. When I was done I powered down the laser and headed out to ISA in Las Vegas for the next 4 days. The only thing I left on in my shop was my PC and a my printer in standby mode. Whe I came home yesterday I tried flipping on the light and nothing happened. I looked and noticed that all the standby lights on my other devices where off ans so was the PC. I thought maybe a circuit tripped or something. I went to the breaker and noticed that nothing was tripped. I headed back to the shop with the flashlight and tried a few things(unplugged everything, etc). Finally I noticed that the power was coming into the main GFCI unit and stopping there. I couldn't reset the GFCI so I waited until this morning to go buy another.
This morning I shut off the power and replaced the outlet. I pushed the reset button, flipped the circuit, and tada, I had power. $12 later I was happy so tunred off the breaker and plugged everything back in. I went to turn the breaker back on and poof their was no power again. I pressed the reset on the GFCI and it stayed on for about 5 secs and poof it went off once more. I removed all the plugs and reset it again. Lights were on and their was power. So one by one I plugged all the devices in and when I got to the laser, poof, the power went out. I checked the fuses in the laser and nothing blown.
So everytime I plug the laser in, it trips the GFCI unit. The laser is not powered on, just plugged in. Any suggestions? Do you think the power supply just simply died? I'm hoping to get a few suggestions to try before I dismantle the PS to see if anything is blown. I sniffed around and didn't smell any blown caps or components so I'm not sure what might have happened while I was away.
Anyways, I'd love to hear any troubleshooting tips before my $12 GFCI turns into several hundreds for a PS.
Thanks!
