Help ! laser is not firing ..


The message I sent to the seller ....





It was cutting, and it stopped.


There is no output from the laser tube.


The water pump is running , water temp 19 Degrees Celcius


the X and Y axis move ok, but the laser does not fire.


The test button on the Laser PSU does nothing.
The pulse button on the keypad does nothing
The water flow light is ok on the controller


Please help !


.......



Soooo ... any of you had anything similar and solved it ?
How do I test the Laser PSU ?
Is there any way to test the tube ?

TIA
