It’s time I took the CO2 laser from the Chinese cutter and attached it to the gantry of my BlackToe CNC mill. Effectively increasing the size of the cutting bay from the tiny 5×8″ to a whopping 2’x 4′ – the small size of the cutting area was starting to become annoying – and it seemed ridiculous […]

I got an email from Dan Wilson about the recent Jarre gig for the Monaco royal wedding. Looks like an excellent concert, although the laser harp had some issues – and JMJ didn’t look too happy about it. I found this video on Dailymotion (with apologies in advance for all the ads they make you […]

Since the laser cutter has a fixed tube, and “flying” mirrors – it’s critical to get the alignment right over the full range of gantry movement. It occurred to me that if I could actually *see* the path of the laser, it would make mirror alignment a whole lot easier. Video also features my $25 […]

And things were going so well… When I first connected the software to the cutter I could get no response at all. I examined the supplied parallel cable and found that some of the pins had been pushed in. Nothing that couldn’t be fixed with some needle-nose pliers. So I fixed the cable and plugged […]

2012 UPDATE: Check out the new laser cutter I built from scratch here -> New 24×18″ CO2 Laser Since building the CNC router last year I’ve become increasingly interested in adding a laser cutting/engraving head.

Build yourself a laser harp. At least that’s what Connor Thomas did – he’s been working on it for some time and he just sent me an email to let me know that the results came in and he scored 100%. Nice one. Here he is next to the tri-fold display.
