Hi,Bernd
I'm not sure if you've missed something...And have you tried to swap the driver module of the extruder motor with the driver module of the x or y axis motor?Cuz as you say,i guess there is insufficient driver ability to the extruder motor.Here is the driver module:

Yes , I have it Set to 1,15volts.

I swap one from the z axis with the one from the extruder Motor ! But is still the same problem.

Another question,does the motor of your extruder work when you plug the input of it into the motor port of x or y axis on the motherboard?If it doesn't work,maybe the motor of your extruder is broken?

No, everything was great. All engines are running well.
I can see the wheel, it rotates when try to print. I use a flashlight and also in the right direction.

Alright,then has the voltage between them been measured already?It is right?

If that is also correct,the reason i can think can only be the gap between Philip screw and gear,you can adjust the gap little by little until it is appropriate.

Yes the Voltage is right.
I can not unfortunately adapt because I can not get close to this Philip screw or set at all.

Hi,Bernd
I just looked the extruder as yours,and i tried to plug the filament into it,i found the gap was enough tight.So i think the pressure is sufficient to the filament to flow.
And you had better check if the extruder temperature has reached the lowest working temperature for your filament,if that is right,pleaser verify your nozzle is not clogged again.
Finally,if those are right,you can have a try to increase a little dirver voltage to 1.3~1.5V by adjusting the potentiometer screw below:

i did this and put on several volts 1,35 1,45 and 1.5v ... and now only buzzing the engine but nothing else happens. That just can not be right

Its so weird...Sorry to tell you that you had better check them above all carefully again,maybe you missed something indeed.Cuz there's no other problem about this.
