3D Printing - Advanced Print Settings
You want the fan to run at 0% speed for the first 2 layers, 50% speed for layers 3 to 5, and 100% speed after layer 5. Which code snippet correctly implements this?

hard📝 Application Q8 of 15
Step-by-Step Solution
Solution:
Step 1: Translate layer ranges to conditions
First 2 layers means layers 1 and 2, so layer < 3 covers that. Layers 3 to 5 means layer 3,4,5, so layer < 6 covers that.Step 2: Match fan speeds to conditions
0 for layer < 3, 128 (50%) for layer < 6, else 255 (100%).Final Answer:
if layer < 3: fan_speed = 0 elif layer < 6: fan_speed = 128 else: fan_speed = 255 -> Option BQuick Check:
Layer ranges match fan speeds correctly [OK]
Quick Trick: Use less than for upper bound in ranges [OK]
Common Mistakes:
- Using <= incorrectly causing overlap
- Wrong layer ranges for fan speeds
- Assigning wrong fan speed values
