Playing with lasers is fun, but they’re sensitive devices and they need proper focusing and cooling. I finally think I’ve found a decent technique to push them into the socket, it takes force and grace at the same time 👌🏻☺️ (and a vice and a massive adjustable wrench, believe it or not 😂)

I don't have my CO2 laser yet, but I do have a diode laser that I discovered a friend had sitting in the box. I'm fostering it indefinitely. Finished set-up this morning. So far I've made a candleholder, wrote bone on a bone, and named one of my kitchen knives.

Giant CNC Partners With Powerful Laser Diode

[Jeshua Lacock] from 3DTOPO owns a large-format CNC (4'x8′, or 1.2×2.4 m), that he strongly feels is lacking laser-cutting capabilities. The frame is there, and a 150 W CO2 laser tube has been sitting in a box for ages - what else could you need? Sadly, at such a scale, aligning the mirrors is a tough and finicky job - and misalignment can be literally blinding. After reading tales about cutters of such size going out of alignment when someone as much as walked nearby, he dropped the idea - and equipped the CNC head with a high-power laser diode module instead. Having done mirror adjustment on a few CO2 tube-equipped lasers, we can see where he's coming from.

Typically, the laser modules you see bolted onto CNC heads are firmly under three watts, which is usually only enough for engraving. With a module that provides 5 watts of optical power, [Jeshua] can cut cardboard and thin plywood as well he tells us even 10 W optical power modules are available, just that he didn't go for one. We reckon that 20 W effective power diodes are not that far into our future, which is getting very close to the potential of the blue box "40 W but actually 35 W but actually way less" K40 laser cutters we cherish. [Joshua]'s cutter is not breaking speed limits, but it's built on what's already there, and the diode is comparatively inexpensive. Equipped with a small honeycomb surface and what seems to be air assist, it's shown in the video cutting an ornamental piece out of cardboard!

We hackers have been equipping CNCs with laser diodes for a while, but on a way smaller scale and with less powerful diodes - this is definitely a step up! As a hacker, you should have at least some laser cutting options at your disposal, and this overview of CO2 cutters and their availability can get you started. We've also given you detailed breakdowns about different sides of laser cutting, be it the must-have of safety, or the nice-to-have of air assist.
