Retraction Calibration Retraction calibration adjusts retraction distance, speed, and acceleration to minimize oozing, stringing, and blobs during non-print moves. Proper retraction settings enhance surface finish, sharp details, and clean transitions between parts. Calibration tools like retraction towers or stringing tests help optimize settings for each filament type and printer setup. Direct drive extruders require shorter retraction distances, while Bowden setups need longer retraction due to filament slack. Proper retraction calibration ensures smooth surfaces, accurate dimensions, and high-quality prints. |
