Hi, I am using 10w diode laser. Would appreciate it if anyone could answer my question. My laser turned off and won’t turn on again. When I try to power on, the adapter light blink and the laser machine still won’t turn on. Anyone have any ideas as to why?
I have also replaced the adaptor. Still blink/flashed
What adaptor are talking about, how it’s connected to the board and what board are you using.
These information should help on finding of the cause of your issue.
The laser is using Ac/dc adapter. Laser turned off during operation. It wasn’t engraving or anything, just turned on.
If I understood and assuming that works before it looks like the adaptor is overcharged.
Maybe a short circuit or faulty connection.
Can you try to turn on the adaptor without laser machine connected? Look if the light on the adaptor still blinking.
When I turned on the adapter without connecting to the laser, the light is on without blinking. It only blinks/flash when I connect it to laser and turn on the laser.
That’s looks like the adaptor is overcharged.
If possible check all your connections on the board are ok. In doubt take note of everything you can (you will need it later) disconnect all the connectors and leave only the adaptor plug connected to the board. Turn on the adaptor, turn on the board and check if the light in the adaptor blinks or stand steady.
I just tried disconnecting the laser to the board. When I disconnected the laser, I can turn on the board just fine. When it is connected to the laser, the adapter start blinking again and cannot the turn on the whole thing.
Assuming that works fine before, and assuming that the laser are correctly connected it looks to me that laser head is damaged.
Does that laser head have a fan?
Does the laser turn on, or the power source turns off immediately?
Normally I point to a undersized adaptor. Specs don’t always match up to the effective behaviour.
