How It Works

E-steps calibration: mark filament 120mm above the extruder, extrude 100mm, measure remaining distance. New E-steps = current E-steps x (requested / measured). Formula: E_steps_new = E_steps_old * (100 / measured_mm). Save with M500 after M92. Recalibrate after changing extruder gear or motor.
