  • Pinout Description
  • The V5 Heat Break Hotend Throat With Teflon Tube for 1.75mm Filament is equipped with a set of pins that enable connection to the extruder's heat block, thermistor, and heater cartridge. The pinout consists of 4 pins, labeled as follows:
  • Pin 1: Thermistor Pin
  • Function: Connects to the thermistor sensor, which measures the temperature of the hotend.
  • Connection: Connect the thermistor wire to this pin, ensuring proper insulation to prevent electrical shorts.
  • Note: The thermistor sensor should be inserted into the hotend's heat block, and its wires should be routed through the Teflon tube to prevent damage from heat.
  • Pin 2: Heater Cartridge Pin (+)
  • Function: Provides power to the heater cartridge, which heats the hotend to the desired temperature.
  • Connection: Connect the positive wire (usually red) of the heater cartridge to this pin.
  • Note: Ensure the heater cartridge is properly seated in the hotend's heat block, and its wires are securely connected to prevent electrical shorts.
  • Pin 3: Heater Cartridge Pin (-)
  • Function: Provides the return path for the heater cartridge's power.
  • Connection: Connect the negative wire (usually black) of the heater cartridge to this pin.
  • Note: Ensure the heater cartridge wires are properly insulated and routed through the Teflon tube to prevent electrical shorts.
  • Pin 4: Heat Break Pin
  • Function: Connects to the heat break, which is a critical component of the hotend's thermal system.
  • Connection: Connect the heat break wire to this pin, ensuring proper insulation to prevent electrical shorts.
  • Note: The heat break wire should be securely attached to the heat break component, and its insulation should be rated for high-temperature applications.
  • Connection Structure
  • To connect the pins properly, follow this structure:
  • 1. Connect the thermistor wire to Pin 1, ensuring proper insulation.
  • 2. Connect the positive wire (red) of the heater cartridge to Pin 2.
  • 3. Connect the negative wire (black) of the heater cartridge to Pin 3.
  • 4. Connect the heat break wire to Pin 4, ensuring proper insulation.
  • Important Considerations
  • Ensure all wiring is properly insulated and rated for high-temperature applications.
  • Verify the connections are secure and won't come loose during operation.
  • Follow proper safety guidelines when working with electrical components and high-temperature systems.
  • By following this documentation, you should be able to properly connect the V5 Heat Break Hotend Throat With Teflon Tube for 1.75mm Filament to your extruder's heat block, thermistor, and heater cartridge.

### Example 2: Python Script for Temperature Control Using RPi
In this example, we'll demonstrate how to control the V5 Heat Break Hotend Throat With Teflon Tube for 1.75mm Filament using a Python script running on a Raspberry Pi (RPi).
```python
# Python script for temperature control using RPi
import RPi.GPIO as GPIO
import time
# Set up GPIO pins for heat break and thermistor
heat_break_pin = 17
thermistor_pin = 23
# Set up temperature control
target_temperature = 220  # set target temperature
pwm_frequency = 100  # set PWM frequency
GPIO.setmode(GPIO.BCM)
GPIO.setup(heat_break_pin, GPIO.OUT)
GPIO.setup(thermistor_pin, GPIO.IN)
while True:
    # Read thermistor temperature
    temperature = read_thermistor_temperature(thermistor_pin)
    
    # Calculate duty cycle based on temperature
    duty_cycle = calculate_duty_cycle(temperature, target_temperature, pwm_frequency)
    
    # Control heat break using PWM
    GPIO.output(heat_break_pin, GPIO.HIGH)
    time.sleep(duty_cycle)
    GPIO.output(heat_break_pin, GPIO.LOW)
    time.sleep(pwm_frequency - duty_cycle)
def read_thermistor_temperature(pin):
    # Implementation of thermistor temperature reading function
    pass
def calculate_duty_cycle(temperature, target_temperature, pwm_frequency):
    # Implementation of duty cycle calculation function
    pass
```
Note: The `read_thermistor_temperature` and `calculate_duty_cycle` functions are not implemented in this example and should be replaced with actual implementations specific to your 3D printing system.
