The extruder motor moves from side to side (like vibrating) but doesn't turn fully.

The step stick is fine and the motor is fine.

It is a geared extruder and hasn't printed anything yet.

I am using marlin and have included my config file.

Help appreciated

Take a look at this thread: [forums.reprap.org]

How do you know the stepper is fine? Does it work on a different port?
If so, then try to run the stepper without the gear for test. If it spins, then:
the friction of the gears is to high or
the current setting ( Vref) is to low or
the jumpers on the extruder port have bad contact.
