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?
