I write you as I have a new problem with my Felix 3.0.
The Extruder motor suddendly stopped working after 3 years of activity, this happened after the filament got stuck while I was away, thing already happened in the past some times.
I noticed the motor wasn't working anymore, so I tried to replace it with a new one, but it still doesn't work. I also replaced the whole mother board with a new one, and the motor (only this one) still doesn't work on manual control.
If I launch a print, while printing the pinion run, so the motor is working, but on manual control there is no way to make it move (eg for filament change or so).
Anyone can help me?
