stepper motor nema 34 Add a laser module to Reprap Guru Prusa i3

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 . It has its own 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.


  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). I have connected to the D9 pins
  3. Now need to figure out where to connect the PWM from the laser module to the Arduino Mega 2560 board

Cloudray Stepper Motor Series has set the standard for quality, reliability, and durability in stepping motors. The precision of our Torque Power motors is matched only by the dependability of their performance. All Torque Power motors are bi-directional and totally enclosed with permanently lubricated ball bearings for long-lasting, smooth operation.

High Torque, High Precision and Long life is Cloudray's core advantage
Low vibration,Low heating, No loss of step
Fast Response,Better Acceleration Performance
Thanks to a robust design they can be selected for the harshest environments. Precise, open-loop, speed and position control can be achieved with the application of full step, half step, or microstepping electronics.
Higher Resolution,Avoidance of Resonance Regions
Stepping angle is adjustable( rang in 18°±5%), 0.9 °stepper motor's stepping angle is smaller, fineness is higher and positioning is more accurate.Avoiding vibration,runs more smoothly and gets lower noise.
Sturdy structure, extremely long life
High quality materials including bearings and shaft made in Japan
Robust assembly, high speed range, and exceptional performance in even the harshest environments make Cloudray Stepper Motors the perfect solution for demanding positioning applications.
Short length and light weight allow them to be used in highly integrated systems
