For standard A4988 or TMC2208/2225 drivers on Creality boards, a Vref of roughly 0.58V to 0.6V is often recommended to target ~0.8A current safely.
This technical guide provides the full architectural data, electrical limits, mechanical pinouts, and custom driver calibration requirements for the BJ42D15-26V10 motor. Technical Specification Matrix Practical Applications This motor is a standard "workhorse"
The BJ42D15 26V10 stepper motor has a high holding torque of 4.5N.cm, making it suitable for applications that require high torque and precise positioning. The motor also has a low detent torque of 1.5N.cm, which ensures smooth and precise movement.
The "D15" designation creates a body length of approximately 40mm . Excluding the rear protrusion, the total motor depth is roughly 48mm. This is shorter than a standard "D20" or "D25" stack, making the BJ42D15 ideal for space-constrained designs where torque requirements are moderate.
