Filament Tab (Process > Filament)

Nozzle Temperature: 235-245°C (initial layer: 240°C). Higher (up to 255°C) for better flow with high-speed PETG, but lower to reduce stringing.
Bed Temperature: 80-90°C (initial layer: 85°C). Ensures adhesion without warping; use textured PEI plate and glue stick if lifting occurs.
Max Volumetric Speed: 20 mm³/s (calibrate up to 30 mm³/s for your filament's high-speed rating, but cap lower for quality).
Retraction Length: 0.8-1.2 mm (Bowden setup; test 1.0 mm to minimize oozing on threads).
Retraction Speed: 40-50 mm/s.
Z-Hop Height: 0.2 mm (enables during travel to prevent scarring surfaces).
Cooling Fan: 0% for first 3 layers (prevents warping), then 30-50% (enable auxiliary fan at 100% if your enclosure supports it for smoother walls).
Filament Flow Ratio: 0.95-1.00 (calibrate via flow test; slight underextrusion helps clean threads).

Layer Height: 0.12-0.2 mm (use 0.16 mm for balance; lower fo
