What is retraction?
Retraction is the backward pulling of filament in the extruder during non-print movement. Prevents stringing - fine threads between model parts.
How it works
When the printer travels through empty space, the extruder pulls filament back by a few mm. This creates negative pressure in the nozzle - plastic doesn't leak, doesn't trail behind the head.
Settings
- Direct drive: 0.5-2 mm
- Bowden: 3-8 mm (longer path)
- Speed: 30-60 mm/s
- PLA: standard
- PETG: less (else stringing in hotend)
- TPU: minimal or off
