Description
This stepper motor with integrated lead screw serves as a critical motion component for the ELEGOO Mars 4 Ultra 3D printer’s Z-axis. Engineered around the high-performance 17HS4401 motor, it delivers precise vertical positioning crucial for layer accuracy. With a 1.8-degree step angle and 1.5A current per phase, this assembly provides consistent, controlled movement, further enhanced by its 4.2 KGCM holding torque to prevent layer shifting.
The included 304 stainless steel lead screw, measuring 8mm in diameter and 260mm in length, is designed for exceptional durability and smooth linear translation. Replacing a worn or damaged stepper motor and lead screw assembly is essential for maintaining your printer’s original performance, resolving issues like Z-wobble, layer lines, or incomplete prints, and ensuring the longevity of your machine. This unit ensures your printer continues to produce high-resolution, dimensionally accurate resin models.
