A user reports their heated bed is not reaching the set temperature. Which of the following is the most likely cause?
AFaulty thermistor or temperature sensor
BUsing a glass bed surface
CPrinting with PLA filament
DHeated bed set too low
Step-by-Step Solution
Solution:
  1. Step 1: Identify components affecting bed temperature

    The thermistor measures bed temperature; if faulty, it may report wrong values causing heating issues.
  2. Step 2: Evaluate other options

    Glass surface and filament type do not affect bed heating; setting too low would not prevent reaching set temp.
  3. Final Answer:

    Faulty thermistor or temperature sensor -> Option A
  4. Quick Check:

    Bed not heating = Sensor fault likely [OK]
Quick Trick: Check thermistor if bed won't heat properly [OK]
Common Mistakes:
MISTAKES
  • Blaming bed surface material
  • Confusing filament type with heating
  • Assuming low temp setting causes no heat
