Getting Started In Laser Cutting

If you were to walk into most of the world’s hackerspaces, it’s likely that the most frequent big-ticket tool you’ll find after a 3D printer is a laser cutter. A few years ago that would inevitably been one of the ubiquitous blue Chinese-made K40 machines, but here in 2024 it’s become common to see something far more sophisticated. For all that, many of us are still laser cutter noobs, and for us [Dominic Morrow] gave a talk at last summer’s EMF Camp in the UK entitled “Getting Started In Laser Cutting“. [Dominic] is a long-term laser cutting specialist who now works for Lightburn, so he’s ideally placed to deliver this subject.

It’s fair to say that this is an overview in the time available for a hacker camp talk rather than an in-depth piece, so he takes the approach of addressing people’s misconceptions and concerns about cutters. Perhaps the most important one he addresses is the exhaust, something we’ve seen a few in our community neglect in favor of excessive attention to laser cooling or other factors. An interesting one for us though was his talking about the cheaper diode lasers, having some insight into this end of the market is valuable when you have no idea which way to go.

We’re sorry to have missed this one in the real world, perhaps because of the allure of junk.

Looking Forward To EMF 2024

It’s that time of year again when some parts of our community travel out into the countryside to spend time with each other under canvas in a field somewhere with power and fast internet — it’s hacker camp season. Here in Europe that means it’s the turn of the British hackers to have the year’s large event, in the form of the latest incarnation of Electromagnetic Field. We’ll be there, camera and microphone in hand, and with luck we’ll be able to bring you a flavour of the event.

The atmosphere that comes from being in the company of several thousand like minds is stimulating enough, but what makes these outdoor events special is that the villages become so much more than simply a group of geeks at a table with their laptops. Where else can one find a tea room run by a hackerspace except courtesy of MK Makerspace, or a fully functional pop-up motor racing circuit from Hacky Racers?

This year’s event badge is an interesting one, the ESP32-S3 powered and hexagon-shaped Tildagon. It’s a bold attempt to redefine the event badge away from a one-off trinket into one that lasts across multiple events, with custom “Hexpansions” like the petals on a flower, intended to have new ones appear on an event by event basis.

If you’re going to be at EMF then maybe we can join you for a pint, otherwise we’ll be bringing you the best that we find there. To whet your appetite, here’s something of the last one.
