Printer calibration basics in 3D Printing - Mini Project: Build & Apply

Printer calibration basics

📖 Scenario: You have a new 3D printer and want to make sure it prints objects accurately. Calibration helps adjust the printer settings so the printed parts match the design dimensions.

🎯 Goal: Build a simple calibration checklist to verify key printer settings like bed level, nozzle temperature, and extrusion rate.

📋 What You'll Learn

Create a dictionary with common calibration steps and their descriptions

Add a variable for the recommended nozzle temperature

Write a loop to list all calibration steps with their descriptions

Add a final confirmation step to complete the checklist

💡 Why This Matters

🌍 Real World

3D printer users must calibrate their machines to ensure prints come out correctly sized and with good quality. This checklist helps beginners follow the right steps.

💼 Career

Technicians and hobbyists working with 3D printers need to understand calibration basics to maintain and troubleshoot printers effectively.

1

Create calibration steps dictionary

Create a dictionary called calibration_steps with these exact entries: 'bed_leveling' with value 'Adjust the print bed to be flat and level', 'nozzle_cleaning' with value 'Clean the nozzle to prevent clogs', and 'extruder_test' with value 'Check extrusion flow rate'.

# Create the calibration_steps dictionary with exact entries
# Your code here

Use curly braces to create a dictionary with keys and string values exactly as shown.

2

Add recommended nozzle temperature

Add a variable called recommended_nozzle_temp and set it to the integer 210, which is the recommended nozzle temperature in degrees Celsius.

3D Printing

calibration_steps = {
    'bed_leveling': 'Adjust the print bed to be flat and level',
    'nozzle_cleaning': 'Clean the nozzle to prevent clogs',
    'extruder_test': 'Check extrusion flow rate'
}
# Add the recommended_nozzle_temp variable below
# Your code here

Need a hint?

Assign the integer 210 to the variable recommended_nozzle_temp.

3

List all calibration steps

Use a for loop with variables step and description to iterate over calibration_steps.items(). Inside the loop, write a comment line showing how you would display each step and its description (e.g., # Display step and description).

3D Printing

calibration_steps = {
    'bed_leveling': 'Adjust the print bed to be flat and level',
    'nozzle_cleaning': 'Clean the nozzle to prevent clogs',
    'extruder_test': 'Check extrusion flow rate'
}
recommended_nozzle_temp = 210

# Use a for loop to iterate over calibration_steps and show each step
# Your code here

Need a hint?

Use a for loop with two variables to get keys and values from the dictionary.

4

Add final confirmation step

Add a new entry to the calibration_steps dictionary with key 'final_check' and value 'Confirm all settings and start test print'.

3D Printing

calibration_steps = {
    'bed_leveling': 'Adjust the print bed to be flat and level',
    'nozzle_cleaning': 'Clean the nozzle to prevent clogs',
    'extruder_test': 'Check extrusion flow rate'
}
recommended_nozzle_temp = 210

for step, description in calibration_steps.items():
    # Display step and description
    pass

# Add the final_check entry to calibration_steps
# Your code here

Use the dictionary key assignment syntax to add a new entry.
