If you are reading the Lightburn community forums, you in all probability now have a laser cutter of some kind. But, if you are like most of us, you can usually be tempted into one more “deal.” [Dkj4linux] has a submit wherever he bought a $79 laser engraver (now selling for involving $59 and $65, we noticed). Like most of these affordable engravers, the equipment usually takes a proprietary controller with Windows-only software. No shock that [Dkj4linux] would want to use…um… Linux. The reply? Rip the board out and switch it with an previous spare.
The machine seems effectively made, as you can see in the online video below. For that price tag, you get a 3-watt laser head (that is probably way less than that in conditions of optical electric power), and a make place of 220x290mm. The controller was in a compact steel enclosure, and it was quick to merely unplug the two axis and the laser manage cable.
This would be a terrific use for an aged 3D printer controller you’ve had in your junk box since the past up grade. It turns out, the board, a JL1, does have common GRBL firmware out there if you question for it. It looks as however the firmware is not perfect, but there are workarounds. We’d almost certainly just ditch the low cost controller and use one of our have, anyway.
Actually, contacting these cutters is a little bit of a stretch considering the fact that at this energy degree, you will have issues slicing something incredibly thick. But it seems to be like it does a credible job of engraving and it in all probability can cut some materials with some endurance.
Of course, you can also make your have frame, increase a couple of stepper motors and just acquire a laser module. Or do a more superior build. But if you needed to try out a laser without the need of a huge expense, a thing like this could be just the ticket.
