motor phase A may be disconnected + hotend failures

after a couple of months of break, I turned on my printer (caresian with Duet Wifi, f.w. 3.0) and I successfully printed for around one day without any issues. The day after (yesterday) I started having the following issues:
- motor phase A may be disconnected on driver 2 (my Z axis)
- random hotend failures
I unplugged the cable of my Z axis and checked, after a while I was able to print again. Then, another hotend failure. From that moment, I had a very strange behavior.
Driver 2 would fail (with the reported error message) making very bad squeaky sounds, then after a while of plugging/unplugging (of course with the duet turned off) I managed to home my printer, started a print and DANG: the extruder started giving the same issue of my Z axis: motor phase A may be disconnected on driver 4.
Should I just throw my Duet in the garbage?

first update to 3.1.1
second those message could also be caused by bad crimping making intermittent contact.
so if after 3.1.1 this persists, consider checking the cables under a microscope and recrimp if necessary.
