If you have purchased this motor from a non-reputable seller, use the following verification steps.

A: Yes, but torque will be approximately 0.12 N·m (57% of rated). You risk missed steps under any load. Use a 24V or 26V supply for verified performance.

BJ42D15-26V10 NEMA 17 hybrid stepper motor primarily manufactured by Keli Motor Group and is widely used as a stock component in Creality 3D printers

Using a multimeter, continuity between Black and Green (≈26Ω) confirms Phase A. Red and Blue (≈26Ω) confirms Phase B. No continuity exists between color groups.

A: Yes, but set the current limit resistor correctly: Vref = 1.0A * (Rsense typical 0.1Ω) * 8 = 0.8V. Many users forget this and fry the motor.
