...But the common denominators in my fires have been the same:
1--While shutting off the laser would prevent further fires, it will do nothing to stop the existing fire--
2--Shutting off the blower would probably do more harm than good--
3--Whenever ANYTHING is on fire, ash and burning debris gets sucked up by the blower...
Ergo--
1- shut off the laser AND add a VERY LOUD ALARM--
2- Do NOT shut down the blower-
3- If some sort of flame detector is to be installed, wouldn't it make sense to install it within the blower hose rather than the laser cabinet?
That was my experience with a fire as well. #2 especially. It was the blower pulling the flames sideways that helped keep it from being a tall flame that burned up lots of stuff.
