Yesterday, the right heating assembly failed completely with no obvious damage - it just died without warning. The failure occurred mid-print; the print continued but at reduced temperature, resulting in complete failure of the model. The replacement part has a delivery date of January 2nd.
I’ve checked the connection to the board, inspected all the cables, and found nothing visibly wrong. The TH board itself is brand new.
Bambu Lab really makes some rock-solid hardware.
