Чести проблеми и решения

Ghosting/Ringing

Echo-like wavy lines appearing on the walls of the print, typically after sharp corners, caused by mechanical vibrations during high-speed directional changes. Решение: Tighten all drive belts, reduce the print speed to 60 mm/s for outer perimeters, and ensure Input Shaper (resonance compensation) is properly calibrated.

Stringing

Thin, web-like strands of plastic stretching between different parts of the print, often exacerbated by rapid travel moves. Решение: Dry the filament for 4-6 hours at 50-70°C depending on material, increase retraction distance by 1-2 mm, and increase travel speed to at least 200 mm/s.

Under-extrusion at High Speeds

Gaps, thin walls, or weak layer bonding occurring when the hot end cannot melt the filament fast enough to keep up with the printer’s high volumetric flow demands. Решение: Perform a cold pull to clear the nozzle, calibrate E-steps (M92), increase the nozzle temperature by 5-10°C to improve polymer melt flow, and check extruder gear tension.
