Extruder werkt niet meer - Extruder Stopped functioning

[simmosam 0]

Dear,

today experienced a strange phenomenon with my Original: The extruder motor stopped working: nor when running a print, nor when jogging.

First thought was that the motor was broken, but it's not. Please find beneath what i've tried:

- X motor coupled to the extruder connector: nothing is happening (jogging)

- extruder motor connected to the X connector: motor is functioning

- stepper driver exchanged: no result

- complete electronics board changed (i had a new spare one) => extruder doesn't work

- software and firmware download V12.10 => no result

- firmware download 15.02.1 => when starting the machine makes a sound and all the motors are blocked, even the extruder motor. the download is succesfull and after that you can turn all motors again, jogging the extruder still doesn't work

does anyone has an idea what might be wrong?

gr Sam
