Big Laser Rebuild -
On 8/12/19 a fire started in the Big Laser Cutter. Fortunately, the fire was contained to the Big Laser itself. No one was injured, though there was a lot of nasty smoke in the building.
The fire did cause a lot of damage to the Big Laser and made a mess of FabLab. It could have been a lot worse.
