A user reports that ironing is enabled but the top surface is still rough. What is the most likely cause?
AInfill density is too high
BBed temperature is too low
CIroning speed is set too high
DNozzle diameter is too small
Step-by-Step Solution
Solution:
  1. Step 1: Check ironing parameters

    High ironing speed reduces the time nozzle spends smoothing, causing roughness.
  2. Step 2: Rule out unrelated factors

    Bed temperature, infill density, and nozzle diameter affect other print aspects, not ironing smoothness directly.
  3. Final Answer:

    Ironing speed is set too high -> Option C
  4. Quick Check:

    Rough surface cause = High ironing speed [OK]
Quick Trick: Slow down ironing speed to improve smoothness [OK]
Common Mistakes:
  • Blaming bed temperature for ironing issues
  • Thinking infill affects top surface smoothness
  • Assuming nozzle size causes roughness
