Troubleshooting checklist

• Motor not moving: Verify driver enabled, supply voltage present, and coil continuity.
• Overheating: Reduce driver current, improve cooling, or use intermittent duty cycle.
• Missed steps: Lower acceleration, increase drive current (within spec), or reduce load.
• Noise/resonance: Enable microstepping, add mechanical damping, or change acceleration profile.

In a 3D Printer (e.g., Ender 3, Prusa)

Here, the motor works as an actuator for the extruder or Z-axis. When the printer’s G-code commands a 1mm filament feed, the controller calculates that this equals 100 steps. The motor rotates exactly 100 steps, pushing filament through the hotend. If the motor skipped a step, the print would have a layer shift. The Bachin 424015A is a common NEMA 17
