I initialy bought a laser kit on eBay with 2,5w blue laser and i have updated it with a 5w laser. I am not sure to use all the power of the 5w at this point. I specially make some test around engraving photo portrait in.order To use the machine to make demonstration for private event.
The device works with a raspberrypi who get a picture from a phone over wifi, and concert it in gcode for the cnc laser.
