I went to high school with a kid who head planted into a pole while sledding. Why would someone want to troll the internet passing that garbage on to others? What kind of insecurities motivate that? Compensate much? And that’s ok because I know I am not passing my irrationality on to the next generation. Asside from that the helmet does nothing to lessen my enjoyment of a bike ride. And if they did it’s none of their business anyway. Nobody around me could care less what is or isn’t on the head of the middle aged man riding by. I imagine the people around me judging me the same way I would judged another kid with a helmet back when I was one. I never wore one until I had a kid and wanted to be a good example to her. Making it a ton safer, but adding to the price.ĭIY and save some money, IMO. Making an enclosure is the best, but ironically, that would probably constitute a laser system in the eyes of the FDA, and then the manufacturer would need to provide interlocks and keyswitches and so on. IANAL.īut should you go through the OSHA laser safety page linked above? Oh my, yes! Just like you should understand how to safely operate a table saw or a drill press. So even though the device is dangerous and being put in the hands of people who do not understand how to mitigate the risk, it’s probably legal both to import and to use. And it’s a good chance that the 1.5 W laser heads on these things say 1.5 W on them. The laser head, which you screw on to the moving frame yourself, is probably a laser product rather than a system. ![]() This is where the proper setup and use of a self-built laser system would come into place. OSHA makes rules on the use of lasers in the workplace. (The FDA also regulates laser shows, b/c the viewers are potentially exposed.) Systems have stricter requirements, but laser products are only subject to labelling requirements. But my understanding is:įDA regulates the manufacture of laser products and laser systems. Laser safety laws are a mess, so somebody correct me if I’m wrong, please. Posted in Laser Hacks, Tool Hacks Tagged grbl, laser cutter, laser engraver Post navigation But if you wanted to try a laser without a big investment, something like this could be just the ticket. Of course, you can also make your own frame, add a few stepper motors and just buy a laser module. But it looks like it does a credible job of engraving and it probably can cut some materials with some patience. Honestly, calling these cutters is a bit of a stretch since at this power level, you’ll have trouble cutting anything very thick. We’d probably just ditch the cheap controller and use one of our own, anyway. It looks as though the firmware isn’t perfect, but there are workarounds. It turns out, the board, a JL1, does have standard GRBL firmware available if you ask for it. This would be a great use for an old 3D printer controller you’ve had in your junk box since the last upgrade. The controller was in a small metal enclosure, and it was easy to simply unplug the two axis and the laser control cable. For that price, you get a 3-watt laser head (that is likely way less than that in terms of optical power), and a build area of 220x290mm. The machine looks well constructed, as you can see in the video below. The answer? Rip the board out and replace it with an old spare. No surprise that would want to use…um… Linux. ![]() ![]() Like most of these cheap engravers, the machine takes a proprietary controller with Windows-only software. But, if you are like most of us, you can always be tempted into another “deal.” has a post where he bought a $79 laser engraver (now selling for between $59 and $65, we noticed). If you are reading the Lightburn forums, you probably already have a laser cutter of some kind.
