The laser arrived like this:
This summer, a couple of early adopters in the Netherlands got together to figure out all the pesky little details that come up when you’re really just in pioneering mode. Make no mistake: this thing is far from ready for mainstream use. The laser itself is quite nice and ready to go, and definitely workable as far as all the mechanics go. But the electronics and software are still work-in-progress (I’m using the VisiCut software – which includes a driver that talks directly to the laser’s firmware over Ethernet).
Nevertheless – early as it may be, the total cost is less than €1,500 and you end up with an A4-sized laserable workspace which can cut up to 5 mm wood panels and 6 mm acrylic (engraving is more involved, but getting there). One of the first things we tried was this:
Sure enough, the circle is a snug fit and turns perfectly. Excellent alignment!
I’ll describe a few more details of this setup in the coming weblog posts, but also want to point out that you too can end up with such a laser cutter (just make sure to arrange for ventilation – you’ll quickly get very tired of the burning smell and fumes).
There’s a project by the designers of the replacement electronics, called LaOS (Laser Open Source) – and it’s definitely the best place to go right now if you want to find out what’s going on. Warning: the site is currently undergoing a messy transition to a new wiki – I’ve helped out a bit and am sure they’d love to see more people join in the effort of making this thing more practical for the non-hacker crowd.
One little gotcha: these 35 W laser cutters are produced in China and then tested/resold by a company in the UK, and they are really large and heavy. Having one shipped from the UK to you is fairly expensive, because of the delicate glass laser tube (several hundred Euro, most likely). We got around that by getting organised and doing a “group buy”, with one person actually volunteering to go to the UK, load his car up with a bunch of laser cutters, and driving back (!). Still pricey, but less so, and I think the UK vendor is in fact willing to make arrangements when enough units are being purchased and shipped at the same time. Anyway – it’s an aspect to keep in mind.
But oy, oy, oy, this personal fabbing is fun :)
