Чести проблеми и решения

Layer Shift

Horizontal shifting of upper layers is often induced by loose belts or skipped motor steps under heavy acceleration. The CoreXY kinematics require precise belt tensioning. Tighten drive belts symmetrically, reduce print speed by 20%, and inspect the grub screws on the stepper motor pulleys. Решение:

Stringing

Thin web-like plastic strands between printed parts typically point to hygroscopic filament or suboptimal retraction. Dry filament at the appropriate temperature (e.g., 50°C for PLA), increase retraction distance by 1-2 mm, and decrease nozzle temperature by 5°C. Решение:

Ghosting / Ringing

Repeating echo-like lines on part walls post-cornering arise from mechanical vibrations. Reduce print speed to 60 mm/s, ensure belt tension is optimal, and enable resonance compensation (Input Shaper in Klipper or Marlin). Решение:

Under-extrusion

Thin, brittle walls indicating starvation of flow. Execute a ‘Cold pull’ procedure to clear partial clogs, calibrate E-steps with the M92 command, and verify extruder gear tension. Решение:
