I have a Reprap Guru Prusa i3 v2 3D printer. Here is a link to the 192 MB manual. And here is the link to the resources page for the Reprap Guru. Page 58 of the manual discusses electronics.

I purchased a 5.5 W laser from an online resource (AliExpress). It has its only controller module. It has one connector with 3 pins

1. 12 V
2. Gnd
3. PWM

I want to now connect the laser module in-place of the 3D printer nozzle. I have been able to install it physically, but not sure how to connect it to the Reprap Guru Prusa i3 board.

I am not an electrical engineer, but I am capable of connecting wires with clear instructions. Any pointers on how to connect this module to the 3D printer board is appreciated.

Updates:

1. The board of my 3D printer is an Arduino Mega 2560 board.
2. I have been able to power the laser on using the fan connections and it can burn stuff (so it works).
3. Now need to figure out where to connect the PWM from the laser module to the Arduino Mega 2560 board
