How We Calculate This
Recommended Settings
Settings are based on community-tested starting values for each extruder and material combination. These are starting points — fine-tune with retraction towers for your specific setup.
- Direct drive: Short retraction (0.5-3mm) due to minimal filament path.
- Bowden: Longer retraction (3-8mm) to compensate for tube compliance.
- Speed multiplier: Scale the recommended speed range up or down for your hotend (e.g. 0.8 for older hotends, 1.2 for high-flow setups).
- Z-hop offset: Added to your slicer Z-hop height when retracting, reducing nozzle strikes on previously printed features.
