1. Drive mismatch
The stepper motor needs to be matched with the corresponding driver for use. If the driver used does not match the motor, it may cause the motor to shake. For example, if the driver used cannot provide sufficient current, the motor cannot function properly and is prone to vibration.

2. Excessive motor load
The stepper motor has a maximum load capacity, and if the load capacity is exceeded, the motor will experience shaking. For example, in the case of low speed and high torque, if the torque output by the motor exceeds the range it can withstand, it is easy to experience shaking.

3. The power supply voltage of the stepper motor is unstable
The stepper motor requires a stable power supply, and if the power voltage is unstable, it can cause the motor to shake. For example, if a low-quality power supply is used, significant voltage fluctuations can affect the normal operation of the motor.

4. The problem with the stepper motor itself
If there are problems such as damage and aging in the stepper motor, it is also easy to experience shaking.

5. The driving voltage of the stepper motor is too low
If the driving voltage of the stepper motor is insufficient, it will not be able to provide sufficient power to stabilize rotation, resulting in shaking or stalling.

6. The driving current of the stepper motor is too small
Insufficient driving current of the stepper motor can also cause the stepper motor to shake or stall.

7. The stepper motor does not match the load
If the stepper motor does not match its driving load, such as excessive load inertia or friction, the stepper motor will not be able to provide sufficient torque to stabilize rotation, resulting in shaking or stalling.

8. Stepper motor driver issue
The stepper motor driver may have faults or poor connections, such as loose wiring, damaged driver, etc., which may also cause the stepper motor to shake or stall.

9. The problem with the stepper motor itself
The stepper motor itself may have faults or damage, such as rotor eccentricity, poor coil contact, etc., which may also cause the stepper motor to shake or stall.

Some possible reasons:
Unstable driving signal: The motion of the stepper motor needs to be controlled through a series of pulse signals. If the driving signal is unstable, it will cause the motor to shake.
Inappropriate subdivision setting for stepper motor driver: The higher the subdivision of stepper motor driver, the smoother the motor rotation, but it also requires more computation. When the subdivision setting is not appropriate, it can cause motor motion jitter. The parameters of the drive and motor are not matched; Pulse count and step angle, load value, etc.
Excessive motor load: If the motor load is too large, it needs to consume more energy to rotate, which can easily lead to motor motion jitter.
Mechanical structure problem of stepper motor: Mechanical structure problem of stepper motor may also cause motor motion jitter.
