Have you raised the temerature of extruder?
Is the extruder motor moving with no filament when it's connect to extruder mtor slot?

Dear friends
please try the following ways to solve the problem.
1.the extruder will move until the temperature was raise to 180 degrees for PLS,240 degrees ABS.Please check whether the extruder is heated up.
2.please swap the driver board with x-axis,if x-axis is working,the driver board is good.
3.please connnect the motor wire of the extruder to x-axis .if working,the stepper motor is good.
4.please re=download the firmware.Please refer to attachment.
If all above methods do not work,please contact the customer service.
