About 50% through a print, my Mini started to make some unusual noises. When I looked, I saw that the bed had stopped moving, the print head was only moving side-to-side (X-axis) and up (Z):
I cancelled the print in Cura and attempted to move the bed via the “Y->” and “Y home” buttons. I could hear the motor respond, but nothing was moving.
Throughout, there is also a rhythmical but intermittent clicking-sound audible. This sound continued whether the motors were engaged or not.
Please see the linked videos for reference.
I’ve had this printer since mid-August and have done at most 20 prints on it, most of them flawless.
