Creality 3D Stepper Motor 3204120126 for K1 3D Printer

The Creality 3D 3204120126 stepper motor is a replacement part engineered for the K1 3D printer. This stepper motor features a 1.8° step angle, a circular D5 shaft and is compatible with 2GT-20 timing pulleys, providing the precise, repeatable motion required for 3D printing axes.

Advantages

The motor delivers consistent positional accuracy and smooth operation suitable for layer-to-layer motion control. Its compact design and standard shaft diameter make it compatible with common pulleys and couplings used in Creality printers. The unit's black finish and OEM-compatible form factor allow straightforward installation as a spare or replacement part.

Suitable for

• Replacement of a faulty or worn stepper motor in Creality K1 printers
• Use in X, Y or Z axis drive applications that require a 1.8° step angle
• Integration with 2GT-20 synchronous belts and pulleys

How to use

Power down the printer and remove any panels necessary to access the existing motor. Detach the motor from its mount and disconnect the wiring harness, noting pin orientation. Mount the Creality 3204120126 motor in the original position, secure the fasteners, and reconnect the wiring using the same connector orientation. If required, fit a 2GT-20 pulley to the 5 mm shaft and ensure proper belt tension and alignment before restoring power and testing axis movement.

Recommendations

Use this stepper motor with firmware and driver settings that match a 1.8° step angle. Verify mechanical alignment and belt tension after installation to prevent skipped steps; if replacing a motor, confirm wiring compatibility with the printer control board to avoid damage.
