Mokey is an reasonably priced DIY laser engraver
September twenty second, 2022—
All makers love lasers and so they make nice store instruments. Even low-power lasers can engrave quite a lot of supplies. Slicing materials requires extra energy, with the most well-liked slicing lasers being CO2 with energy between 10W-100W. However the small, reasonably priced strong state laser modules can minimize some supplies, like acrylic, for those who get a strong sufficient mannequin. In order for you an reasonably priced approach to make use of a kind of, then the Mokey Laser v1.0 is value taking a look at.
Lasers like these can engrave and minimize materials, which suggests they will completely damage you — your eyes are particularly weak. Should you’re going to construct one thing like this, be sure you perceive the best way to function it safely. It isn’t proven within the video, however you need to completely use some form of shielded enclosure that may deal with the wavelength and energy of the laser you utilize. Even with such an enclosure, you need to put on the suitable security goggles.
This design cuts prices by using 3D printer-style components and by omitting the optics which might be vital for CO2 lasers. As a result of strong state laser modules are so compact, it’s sensible to maneuver them on a gantry in the identical approach as a 3D-printer’s extruder as an alternative of redirecting the laser beam with mirrors and lenses.
The construction of the Mokey Laser v1.0 is 8020 aluminum extrusion, which additionally acts as rails for the V-roller wheels on which the gantry rides. A lot of the different components are 3D-printed, with normal stepper motors and GT2 belts offering movement. An Arduino Uno board controls these stepper motors by a CNC Protect V3 with A4988 drivers. Should you construct this, you’ll have many software program choices. As proven, it runs GRBL 1.1 and that’s suitable with virtually each open supply g-code sender on the market, together with some which might be add-ons for Inkscape so you possibly can management the laser from the identical software program you utilize to create toolpaths.
The overall construct price with the invoice of supplies introduced is $402.61, which makes this fairly reasonably priced for the scale and functionality.
