Creality Official 42-40 Stepper Motor With Extruder Gear
The Creality 42-40 motor from Comgrow is designed for E-axis extrusion on several Ender and CR-10 models. It features a 1.8-degree step angle and a 0.4 N.m holding torque with 1 A per phase. The unit is marketed as an official Creality part, ensuring compatibility with Ender 3, Ender 5, CR-10, and related printers. It offers stable speed and reduced risk of missed steps during extrusion, alongside relatively low noise for standard printing cycles.
Key points: compatible with multiple Ender/CR-10 configurations, 1 A per phase, but note that the connecting cable is not included. This motor emphasizes extrusion stability and predictable performance for reliable prints.
Creality 3D Printer 42-40 Stepper Motor for CR-10 and Ender-3 Series
This KOYOFEI 42-40 motor targets Ender and CR-10 E-axis uses, offering a 1.8-degree step angle and 0.4 N.m holding torque with about 0.8 A per phase. It is described as a high-quality, low-noise motor designed to deliver smooth, consistent extrusion without step losses. The motor’s stability helps prevent under-extrusion or over-extrusion caused by driver irregularities, making it a solid option for those upgrading or replacing worn E-axis motors.
Highlights: broad compatibility with Ender-3/Pro and CR-10 series printers, reduced noise, and dependable extrusion control. Cable not included, so confirm wiring compatibility with your board before purchase.
Creality Official 42-40 Stepper Motor for X/Y Axis
Creality’s official 42-40 motor is presented as suitable for X, Y, and E axes in a range of CR-10 and Ender series printers. The unit uses a 1.8-degree step angle and 0.4 N.m holding torque with a 1 A per phase rating. It is promoted as low-noise and high-precision, designed to minimize step loss and irregular extrusion during movement. This makes it a practical all-round option when upgrading multiple axes or replacing worn motors across a printer.
Note: the description emphasizes quiet operation and stable extrusion, which can contribute to smoother layer transitions and reduced mechanical vibration during prints.
STEPPERONLINE Nema 17 Stepper Motor 59Ncm
The STEPPERONLINE Nema 17 motor offers a high holding torque of 59 Ncm (approximately 83.6 oz-in), making it suitable for demanding drive applications in 3D printers and CNC machines. With a standard NEMA 17 footprint, 4-wire, and 1.65″ square body, it provides strong torque with a 1.8-degree step angle. This motor is commonly used in extrusion drives, gantry motor moves, and other printer operations requiring robust torque and reliable performance under load.
Strengths include high torque delivery and compatibility with most NEMA 17-based electronics. Users should verify current ratings on their driver board to avoid overheating or missed steps if running near limits.
Creality 42-34 Z-Axis Stepper Motor
This Z-axis motor is described as Creality’s official 42-34 version, intended for multiple Z-axis configurations across Ender-3 Neo/Max, CR-10S Pro V2, CR-X series and more. It features a 1.8-degree step angle and 0.8 A per phase with a 0.4 N.m holding torque, designed to deliver steady vertical movement with minimal backlash and smooth micro-stepping. The product emphasizes low noise and efficient heat dissipation, helping maintain quiet operation during tall prints.
Practical note: ensure your controller can supply the current required by the 42-34 Z-axis motor, and remember that the connecting cable is often not included.
Buying Guide: Key Purchase Considerations And Comparisons
When selecting stepper motors for a 3D printer, consider torque, current requirements, compatibility with your control board, cable length, and noise level. Higher torque helps maintain extrusion pressure and axis movement on larger prints or with flexible filaments, but it can draw more current and generate more heat. Matching motor current to your driver’s capability prevents overheating and missed steps.
Compatibility matters: check that the motor’s form factor (usually NEMA 17 for most consumer printers) fits your hot end, bed, and frame. For E-axis and Z-axis upgrades, ensure the shaft length and connector types align with your existing cables and couplings. Cable length is easy to overlook; many motors ship without cables, so factor in additional wiring or adapters if needed.
Noise and heat: a motor advertised as low noise can improve the printing environment, especially in small labs or shared spaces. Efficient heat dissipation helps preserve motor life during long prints. If your printer uses a quiet stepper driver, you’ll further reduce audible noise and vibrations.
Reliability and origin: official Creality parts or well-reviewed third-party motors with documented performance characteristics are generally safer bets for long-term reliability. When upgrading, ensure firmware and drivers are configured to accommodate the motor’s current draw to avoid electrical issues.
Cost-to-benefit: higher torque motors may be overkill for compact builds, while very low-torque motors may fail to provide consistent extrusion for high-speed prints. Assess your typical print size, material, and speed to strike a balance between performance and durability.
