1. Intermittent connection to hot end. Where did you measure the voltage when you found "From the board no voltage when set temperature"? Depending on the answer, there could be a problem in the 6-pin hot end connector, or with one of the crimp connections at either end of the hot end loom, or with the Duet board. Somebody recently reported a badly-soldered joint on one of the header pins on the Duet.

2. Jammed extruder or intermittent drive to the extruder stepper. Remove the Bowden cable from the extruder. With the power off and no filament in the extruder, does the stepper motor shaft turn freely? If not, does it turn freely if you remove the large gear? If it does turn freely even when there is filament in the extruder, then look at the crimp connections on the extruder wiring loom, and the soldered joints on the extruder connection pins on the back of the Duet. You could also temporarily swap the X axis stepper and extruder stepper connections on the Duet board, then whether then extruder moves properly when you command X axis movements, and vice versa. [Remove power before connecting/disconnecting anything.]
