Auto-Retract Auto-retract is a slicer setting that automatically retracts the filament during non-printing movements to prevent oozing and stringing. When enabled, the extruder pulls the filament back slightly to reduce pressure in the nozzle, minimizing unwanted extrusion. Auto-retract settings typically include retraction distance and speed, which can be fine-tuned based on the material and printer type. Proper use of auto-retract improves surface quality and reduces the need for post-processing, especially in prints with multiple small parts or intricate features. It is an essential feature for achieving clean, precise results in both FDM and multi-material printing. |
