WARNING: Do not look into laser with remaining eye. Pages to do with the Laser Cutter:

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 the FabLab. It could have been a lot worse.

Much of the Laser is still good. Over the last two days a list of needed parts has been developed. Upper end cost estimate for parts is between $2000 to $2500.

Many parts are now competitively supplied on AliExpress. The original maker has been contacted for possible parts.

Money for parts is only a part of the problem. Rebuilding this laser is going to take a lot of work.

Hive13 is a Do-ocracy - Nothing gets done unless you step up and do some work.

Hive13 does not have any paid staff. Hive13 only gets better when Members Do Something.

Task Listing and Volunteer Doers - Thank You for Stepping up.
