Чести проблеми и решения

Stringing

Thin, web-like strands of plastic appearing between separate parts of the printed object. Решение: Dry the filament for 4-6 hours (50°C for PLA, 70°C for Nylon), increase retraction distance by 1-2 mm, lower the nozzle temperature by 5°C, and increase travel speed to 200 mm/s.

Warping

The corners or edges of the printed part detach from the build plate and curl upwards due to thermal contraction and uneven cooling. Решение: Increase the bed temperature by 5°C, add a 5-10 mm brim, use an enclosure (especially for ABS or Nylon), apply an adhesive like a glue stick, and reduce part cooling fan speed to 30% for the first 5 layers.

Under-extrusion

The printed part has thin, fragile walls and structural gaps because not enough plastic is being extruded. Решение: Perform a ‘cold pull’ to clear partial nozzle clogs, calibrate the extruder E-steps (M92 command), increase nozzle temperature by 5°C, and check the gear tension in the extruder.

Layer Shift

Sudden horizontal displacement of the upper layers relative to the lower layers, ruining the geometry. Решение: Tighten the drive belts along the axes, reduce print speed by 20%, verify the tightness of pulley grub screws, and check the condition of the linear bearings.
