Trouble Shooting no Laser Beam
Wondering if I could get your comments about this problem.
Here is description of problem that seems to be repeating.
It’s a RECI 80w tube
After I turn on the laser I do a test fire, that’s ok
Next I run a test engraving.
The job starts to run then after maybe 10 -15 seconds the beam stopped.
The head was moving back and forth, air assist was coming out, and everything seemed ok except no laser beam.
I turned off the machine, and then turned machine back on, reset the display, water pump, exhaust were all running. I tried to do a test burn, no beam.
Turned on machine about a couple of hours later and was able to do test burn, started a job and 10 - 15 seconds into job beam stops.
I went a day of so without being able to test fire with a beam.
Then the next day I get a beam, that stops after 10 15 seconds into job.
Working with manufacture and voltage meter, I check voltage on laser power supply.
Check the voltage on power supply as job was running to make sure controller card was working.
We bypassed the water flow safety connection.
We configured the power supply to fire the laser manually when I touched two wires together.
Everything seemed to pass the tests except no laser beam.
The only thing we haven’t checked is the actually high voltage lead on the tube to see if we have current. Not sure I know how to do this SAFELY.
We’re not sure where the problem may be, tube or power supply.
There’s no issue in getting replacement parts, still under warranty.
I have another tube and power supply on the way, should be here in a week.
I should have order all my spare parts before as planned but I didn’t.
I will be ordering SOON.
Does this sound problem sound familiar to anyone ?
thanks..........pete
