Red laser focus trouble -- WATCH THE AIR PRESSURE PEOPLE

[flip]

So I came in today and started a cut and about a minute in to the cut I noticed that although the air pressure switch was on, the air gauge was reading zero. The knob on top of the regulator was loose and air was bleeding out of it. I don't know how long that was happening earlier in the day, but the laser doesn't seem to be cutting as well as it should -- settings that used to work fine for MDF don't make it all the way through and the kerf is unusually wide.

RED TAG THAT RIGHT NOW

Changes in cutting performance pretty much suggests disaster has occurred.

Be in in a minute to check on it.

Danny,

I've been playing with some air pressure sensors for a project I'm on.  ( http://www.alliedelec.com/honeywell-nscdann100paunv/70375304/ ) They are $20, and support a wide range of voltage.   If the Red Laser doesn't have an air pressure safety interlock ... this could be used in conjunction with ( favorite microcontroller ) to create one and prevent future damage.

I don't see any problem with it.  Lens is fine, air pressure builds, there is no leak around the reg, and the focus is dead on.

???

Green tag.  Can't find any problem.

Thanks Danny, 

Sorry for the false alarm (and not sorry to err on paranoia)
