Solution to printing Bambu PETG-CF with X1C (.4 and .6 Nozzle)

Bambu Lab X1 Series Bambu Lab X1C

I fed all this into Chat GPT and asked for a boil down of successful parameters.

Based on the discussions and contributions in the post, here are the successful print settings for Bambu PETG-CF using a .6mm nozzle, as compiled from various users’ experiences:

General Settings:

  • Nozzle Diameter: 0.6mm (some users also reported success with 0.4mm, but 0.6mm is recommended for better results)
  • Layer Height: 0.24mm (can vary based on specific requirements, but this is a common setting)
  • Print Speed: 100 mm/s (may vary, but generally lower speeds help with print quality)
  • Infill Type: Rectilinear or Gyroid
  • Infill Percentage: 15-20%
  • Wall Settings:
    • Number of Walls: 2
    • Wall Order: Outer walls first
    • Inner/Outer Wall Speed: Match speeds, typically 80-120 mm/s

Temperature and Cooling:

  • Nozzle Temperature: 250-260°C (with some users going up to 270°C)
  • Bed Temperature: 80°C
  • Part Cooling Fan:
    • Minimum: 40% (after 20 seconds layer time)
    • Maximum: 90% (after 6 seconds layer time)
  • Chamber Fan: 70% (adjust based on ambient conditions and print size)
  • Auxiliary Fan: 0-30% (varies based on layer time and print complexity)

Retraction Settings:

  • Retraction Distance: 2mm (some users recommend up to 5mm)
  • Retraction Speed: 40 mm/s (can vary, but faster retraction speeds may help reduce blobs)
  • Z-Hop: 0.4mm (can disable if not necessary)

Special Considerations:

  • Filament Drying: 65-70°C for 8-12 hours before use
  • Flow Ratio: Adjusted to around 0.94-0.96 (some users suggest even lower, around 0.89)
  • G-code Addition: Some users suggest adding G29.1 Z0.03 at the end of the Filament Start Gcode for fine-tuning

These settings are not definitive but reflect the collective experience of users who have had success with Bambu PETG-CF filament. Fine-tuning may still be necessary based on specific printer conditions and print requirements.
