Stepper motor Creality CR-6 MAX 42-34 (MPN 4004100020) for 3D printers

Replacement stepper motor Creality CR-6 MAX 42-34 is designed for use in compatible 3D printers to drive linear axes or extruder mechanisms. It provides precise step control and stable rotary motion for positioning the print head or filament feed. The unit is intended for maintenance, repair or upgrade of motion components and helps restore or maintain print quality and printer functionality.

Advantages

This stepper motor delivers consistent stepping performance and smooth micro-step movement suitable for common FDM printers. It is engineered to match mechanical and electrical characteristics typically found in Creality-series machines, enabling straightforward replacement without extensive adjustments. The motor’s construction supports reliable thermal dissipation during regular printing cycles and reduces stalling risk under expected load conditions.

Suitable for

• Replacing a worn or damaged axis motor on compatible 3D printers
• Repairing or restoring extruder drive functionality
• Upgrading motion components to maintain print precision
• Spare-part stocking for maintenance of Creality-style printers

Key specifications

• Frame size: NEMA 17 (42 mm square)
• Length: approximately 34 mm (motor body)
• Step angle: typical 1.8° per full step (200 steps/rev)
• Rated current: compatible with common 3D printer stepper drivers (check driver current limits before installation)
• Shaft type: single solid shaft for coupling or gear/pulley attachment
• Connector: multi-pin cable connector compatible with Creality wiring harnesses
• Cooling: metal housing for passive heat dissipation

How to use

Power down the printer and disconnect it from mains before replacing the motor. Remove the mounting screws and carefully detach the existing motor from its bracket, noting the wiring orientation and connector type. Install the replacement motor in the same orientation, secure it with appropriate screws, and reconnect the cable to the controller taking care to match pin order. After mechanical installation, verify firmware stepper settings and motor current limits in the printer controller or driver software to ensure correct torque and prevent overheating. Perform manual axis movement checks and then run a test print to confirm proper operation and calibration.

Usage recommendations

Verify compatibility with your printer model and driver electronics before purchase. Use appropriate motor current settings on the stepper driver and ensure secure mechanical coupling to pulleys or gears. Avoid prolonged stall conditions and maintain adequate ventilation around the motor to extend service life.
