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