I have a P1S where suddenly the part fan stopped working. When examining the problem I als noticed that the hotend did not heat anymore. There was no immediate cause detectable.
I found in the forum that it might be caused by the FPC cable between the PCB’s of the hotend. This was replaced, but problem persisted.
In the mean time I have replaced both PCB’s (i.e. extruder connection and toolhead board), I have replaced the FPC cable between both boards, I tried multiple different nozzles, connected and reconnected every possible cable on the toolhead but the problem remains.
Does anyone have another Idea what might be the cause of this problem? I am out of idea’s.
