Hi everyone,
I've a Geeetech i3, and I had to change the extruder fan today. I just unmounted the fan and replaced it, nothing more than that, but when I turned on my 3d printer I realized that the step motor was not working anymore.
Since I have an oscilloscope at home I did a few measurements and it turned out that the motherboard doesn't send any signal to the driver. The microcontroller IO aren't floating, and they have the same impedance as those which are working.
It blowing my mind, it's behaving as if the microcontroller was just not sending orders to the drivers without any reason.
If anyone has an idea...

Hello.
If possible, change the output pin to an unused one.

On the forum I help to use the rod, I don't give fish.
