Чести проблеми и решения

Warping

Corners or edges of the print lift from the build plate due to uneven cooling and thermal residual stress, particularly with high-temperature materials. Решение: Increase bed temperature by 5 °C, use a 5-10 mm brim, utilize a heated enclosure, and apply bed adhesives like glue stick or Magigoo.

Stringing

Thin, web-like strands of plastic appear between separate parts of the print, primarily caused by the filament absorbing ambient moisture. Решение: Dry the filament for 4-6 hours (e.g., 50 °C for PLA, 70 °C for Nylon), increase retraction distance by 1-2 mm, and decrease nozzle temperature by 5 °C.

Under-extrusion

The system fails to extrude enough plastic, resulting in thin, brittle walls and structural gaps across the layers. Решение: Perform 3 to 5 consecutive ‘Cold pull’ procedures to clear nozzle clogs, calibrate E-steps via the M92 command, and check the extruder gear tension.
