Heat break design: Teflon-freeElectrical CharacteristicsOperating temperature: Up to 300C
Recommended heating element: 30W or 40W heater cartridge
Thermal resistance: 10C/W (approximate)Usage Examples### Example 1: Marlin Firmware ConfigurationIn this example, we'll demonstrate how to configure the V5 Heat Break Hotend Throat in Marlin firmware for a 3D printer.```c++
// Marlin firmware configuration#define HOTEND0_HEATER_PIN 2 // Heater pin for hotend 0
#define HOTEND0_THERMISTOR_PIN 1 // Thermistor pin for hotend 0
#define HOTEND0_HEATER_RESISTANCE 10 // Heater resistance in ohms
#define HOTEND0_THERMISTOR_BETA 3950 // Thermistor beta value
#define HOTEND0_TEMP_SETPOINT 210 // Setpoint temperature in Celsius
#define HOTEND0_TEMP_HYSTERESIS 5 // Temperature hysteresis in Celsiusvoid hotend0_init() {
// Initialize heater pin and thermistor pin
pinMode(HOTEND0_HEATER_PIN, OUTPUT);
pinMode(HOTEND0_THERMISTOR_PIN, INPUT);
// Set heater resistance and thermistor beta value
heater[0].resistance = HOTEND0_HEATER_RESISTANCE;
thermistor[0].beta = HOTEND0_THERMISTOR_BETA;
// Set setpoint temperature and hysteresis
setTargetTemperature(HOTEND0_TEMP_SETPOINT, HOTEND0_TEMP_HYSTERESIS);
}
```### Example 2: Python Script for Temperature ControlIn this example, we'll demonstrate how to use the V5 Heat Break Hotend Throat with a Python script to control the temperature of the hotend.```python
import time
import RPi.GPIO as GPIO
import Adafruit_MAX31855.MAX31855 as MAX31855# Set up GPIO pins for heater and thermocouple
GPIO.setmode(GPIO.BCM)
HEATER_PIN = 17
THERMOCOUPLE_PIN = 18# Initialize heater pin as output and thermocouple pin as input
GPIO.setup(HEATER_PIN, GPIO.OUT)
GPIO.setup(THERMOCOUPLE_PIN, GPIO.IN)# Initialize MAX31855 thermocouple driver
thermocouple = MAX31855.MAX31855(THERMOCOUPLE_PIN)# Set desired temperature
setpoint_temperature = 210while True:
# Read current temperature from thermocouple
current_temperature = thermocouple.readTempC()
# Calculate temperature error
temperature_error = setpoint_temperature - current_temperature
# Adjust heater pin to maintain setpoint temperature
if temperature_error > 5:
GPIO.output(HEATER_PIN, GPIO.HIGH)
elif temperature_error < -5:
GPIO.output(HEATER_PIN, GPIO.LOW)
else:
GPIO.output(HEATER_PIN, GPIO.LOW)
# Wait for 1 second before next iteration
time.sleep(1)
