Hi;

My extruder stepper motor is not working. Its just making sound and vibrating. I used different drivers A4988, DRV8825 but result is same. just vibrating. I used the motor in Z axis, its working. I tried different motor with different driver in extruder it made same thing also.

What could be the problem?

... not enough current ... much too high speed ... or motor wires not properly connected ...

... not enough current - Should I adjust the current from the driver?

... much too high speed - Can it be adjusted from the marlin ?

or motor wires not properly connected - Motor is working fine when I plug it to x axis, so this is not the problem?

... you can change the current with the driver, if it has capacities and doesn't overheat.

And yes, you can (should) change the extruder speed or steps/mm ratio in Marlin ...
