Written in Visual Studio 2015 / Visual Basic a converter between the Eagle NC file and the laser engraver Gcode. Later more details. The converter is written for the cheap Banggood laser engraver with communication on 9600 baud and no LCD, and the Prusa ‘look-a-likes’ at 250000 or 115200 baud.
Can be found on Thingiverse.
A laser holder for the X-carriage of a Prusa I3.
Heatsink and 500 mW UV laser from Banggood.
Used a Prusa I3 as base for this laser engraver. With a RAMPS 1.4 controller.
Moved in pins.h the fan from D9 to D8
Made a separate power for the laser with a step-down 12 -> 5 Volt
If you check the schematics of the RAMPS 1.4 you will see the heatbed is seperate powered. Heatbed mosfet is now laser controller.
Replaced M106 and M107 in the Marlin firmware by M03 and M05.
M03 is PWM based. It turns now the laser on. M05 turns laser off.
Details about these modification follows.
