Чести проблеми и решения

Stringing

Characterized by thin web-like plastic strings appearing between separate parts of the print due to filament moisture or poor retraction tuning. Solution: Dry the filament for 4-6 hours at 50-70°C, increase retraction distance by 1-2 mm, reduce nozzle temperature by 5°C, and increase non-print travel speed to 200 mm/s to break the ooze effectively. Решение:

Warping

Corners or edges of the print detach from the platform and curl upwards due to rapid, uneven cooling and thermal stress. This is common with ABS or ASA. Solution: Increase bed temperature by 5°C, add a 5-10 mm Brim to increase surface area, use a closed enclosure to trap ambient heat, apply adhesive (like glue stick or PEI sheet), and reduce part cooling fan to 30% for the first 5 layers. Решение:

Under-extrusion

The printer fails to supply enough plastic volumetrically, resulting in thin, brittle walls, gaps, and severe structural weakness. Solution: Perform a ‘Cold pull’ procedure to clear partial nozzle clogs, calibrate E-steps with the M92 command, increase nozzle temperature by 5°C to lower melt viscosity, and check the extruder gear tension against the filament path.
