An Arduino-Powered Laser Engraver That You Can Build
MichielD99 is a 16 year old Belgian teenage maker. It is amazing that, with the tools and materials available today, a young person, really any person, can create something as sophisticated and professional-looking as this laser engraver.
To drive the machine, he used an Arduino UNO with two NEMA-17 stepper motors and stepper motor drivers he got from AliEXpress. By using AliExpress, he was able to keep the component costs down, with the entire thing costing about US$220. The laser is a 1.8W 445nm module.
Michiel designed the device in such a way that he can also install a Dremel tool as the head. This will allow him to turn it into a CNC router when he wants to.
You can see the complete plans for his build on this Instructables page. There he also includes a Bill of Materials with links to all of the parts available online and PDF and STL versions of all of the template files used to create his engraver.
