Hoisting a laser cutter to the 3rd floor (and other fun you’ll probably never have)



Hoisting a laser cutter to the 3rd floor (and other fun you’ll probably never have)

The folks at Null Space Labs bought a 40W CO2 laser tube in order to build their own laser cutter. Unfortunately nobody really wants to build a laser cutter; they just want to play with a laser cutter. So they ended up biting the bullet and ordering a $4000 model from China. That’s it hovering in midair. This is the story of acquiring the unit and playing around with it once it arrived.

Check out those orange cones in the picture. Hackerspace members put them out to keep the parking spots clear so no damage was caused in the event of an accident. But since they’re located in Los Angeles some of the road warriors didn’t really care and just moved the cones anyway. Luckily the crane hoist to the third floor (they removed one of the windows) ended up going rather well.

So what do you do with a laser cutter like this one? Crack it open and make some improvements. The manufacturer says it can’t cut through steel. Well that’s only if you don’t add some O2 to the cutting process. And the stock mirrors… they’ve got to go. Turns out a simple upgrade boosted the power by about 20% (we’re wondering how they measured that). While we’re talking about optics, might as well upgrade the lens as well. You can see where they’re going with this, and [CharlieX] tells us it is just the first in a series of posts he’ll be working on.
