Connecting the Pulley to a Stepper Motor

To connect the GT2 Timing Pulley to a stepper motor, follow these steps:

1. Secure the pulley to the stepper motor shaft: Use a setscrew or a grub screw to attach the pulley to the motor shaft, ensuring proper alignment and a secure fit.
2. Route the GT2 belt: Pass the 6mm wide GT2 belt through the pulley's grooves, ensuring proper tension and alignment.

Code Examples

Here are two code examples demonstrating how to use the GT2 Timing Pulley in different contexts:

Example 1: Marlin Firmware (Arduino-based 3D Printer)
```c++
// Marlin Firmware configuration file (Configuration.h)

// X-axis motor settings
#define X_STEP_PIN 2
#define X_DIR_PIN 3
#define X_ENABLE_PIN 4

// X-axis pulley and belt settings
#define X_PULLEY_TEETH 20
#define X_BELT_PITCH 2
#define X_BELT_TOOTH_COUNT 200

void setup() {
  // Initialize X-axis motor
  pinMode(X_STEP_PIN, OUTPUT);
  pinMode(X_DIR_PIN, OUTPUT);
  pinMode(X_ENABLE_PIN, OUTPUT);

// Set X-axis motor steps per mm
  float x_steps_per_mm = (X_PULLEY_TEETH  X_BELT_TOOTH_COUNT) / (X_BELT_PITCH  25.4);
  // ...
}
```
In this example, the GT2 Timing Pulley is used on the X-axis of a 3D printer running the Marlin firmware. The code sets up the motor pins, defines the pulley and belt settings, and calculates the steps per mm for the X-axis movement.

Example 2: Python Script (Raspberry Pi-based 3D Printer)
```python
import RPi.GPIO as GPIO
import time

# Set up GPIO pins for X-axis motor
X_STEP_PIN = 17
X_DIR_PIN = 23
X_ENABLE_PIN = 24

GPIO.setmode(GPIO.BCM)
GPIO.setup(X_STEP_PIN, GPIO.OUT)
GPIO.setup(X_DIR_PIN, GPIO.OUT)
GPIO.setup(X_ENABLE_PIN, GPIO.OUT)

# Set up GT2 timing pulley and belt settings
pulley_teeth = 20
belt_pitch = 2
belt_tooth_count = 200

def move_x_axis(steps):
  # Calculate direction and step sequence
  direction = 1 if steps > 0 else -1
  step_sequence = [X_STEP_PIN]  abs(steps)
  
  # Move X-axis
  GPIO.output(X_ENABLE_PIN, GPIO.LOW)
  for step in step_sequence:
    GPIO.output(step, GPIO.HIGH)
    time.sleep(0.001)
    GPIO.output(step, GPIO.LOW)
    time.sleep(0.001)
  GPIO.output(X_ENABLE_PIN, GPIO.HIGH)

# Move X-axis 10mm
move_x_axis(100)
```
In this example, the GT2 Timing Pulley is used on the X-axis of a 3D printer controlled by a Raspberry Pi running a Python script. The code sets up the GPIO pins, defines the pulley and belt settings, and implements a function to move the X-axis by a specified number of steps.

These code examples demonstrate how to use the GT2 Timing Pulley in different contexts, showcasing its versatility and compatibility with various 3D printing systems.
