Stepper motor Positioning inaccurate
 

Hello everyone,

I recently made an A-axis using a stepper motor (OYOSTEPPER)with a worm gear. Each time it moves a fixed angle, after the motor stops, the indexing plate bounces back slightly, about 0.05 degrees.

The acceleration and deceleration curves are set very gently, and the driver's enable hold is also on. I suspect the worm gear's backlash is being elastically released when it stops.

Is there a way to use the driver's "pulse disable" function to lock it immediately after it reaches the desired position? I hope someone can help me.
