Hi digitmakers
You can check if the nozzle's temperature is too low so that the felament didn't melt,
or the diver gear is too tight and trapped with the wheel, just take apart the fan and fix it.

Have watched. Is the motor too hot to run?
There is no heat sink and cooling fan on the motor.

The motor is not hot . The fan placed on the back of the extruder for the me creator model. Please list possible root causes to the problem and I will verify one by one.

Hi
It seems like the extruder motor run too fast, and too much filament came out.
So you can set the esteps in the LCD screen: Control -> Motion -> Esteps
Set it to 95~100, was it much larger than 100 before?

Or you can tighten a little the screw.

Harry ,

After many diagnosis I found the problem it was bad wiring connection to the extruder that make the extruder stepper acting the way shown in the video , after taking the cable wire off the printer and fixing the connection , the printer is working properly .

thanks

If the wiring is ok you will need to adjust the stepper motor controller rheostat to above 1.2 volts .
