Our Review
For $20.39 CAD, the 4-Lead Nema 17 Stepper Motor 24mm / 40mm 42 for Sidewinderx1 & / Extruder X Z-axis 3D packs respectable specs: Step Angle: 1.8 degrees (200 steps/rev), Rated Current: 0.4A per phase, Holding Torque: 45 Ncm. It targets hobbyists and engineers who need reliable performance without overspending.
Mechanical performance was consistent in our testing. Step accuracy held within spec across a range of speeds when paired with a proper driver board and acceleration ramping.
Wiring was straightforward. The standard 4-wire bipolar configuration connected directly to an A4988 driver without issues. Color codes matched common pinout charts.
Overall, the 4-Lead Nema 17 Stepper Motor 24mm / 40mm 42 for Sidewinderx1 & / Extruder X Z-axis 3D fills its role well. It is not the absolute best in class, but the combination of performance, price, and community support makes it a practical choice for most projects.
What We Like
