I'm sure there is a thread somewhere that might address my issue but I tried searching and haven't come across one as I am new to this forum and not sure whre to look.
so I have a 40 watt cheap laser as my learning unit. that unit was functioning fine until one of my employees decides to move it off the bench
on its side to use the space.
now when I test fire the machine it no longer seams to emit any beam.
previously the excited gas would glow when firing at moderate current now it no longer glows at all and arcs high voltage to the metal
enclosure
it does seam apparent that some alignment of the mirrors were shifted when moved and stored horizontally
any sugestions as to the laser tube issue or is it just damaged I cant find any test specs to check with my meter or scope
but the high voltage arc tells me the HV power supply is working.
it does have a hiss when test firing but nothing visual in the tube unit just the audible hiss that I wanna say it had before
thank you for any help in advance
