  1. Hello,

     

    The Problem:

    I recently had this problem where the UM2+ would not start because of the bed not heating up.

    So i ended up unscrewing the heat bed had found this on the connection terminal (See attached photo).

    The UM2+ has a uptime of 7080h where 3078h printing, with 2258m of fillament that has gone thru, over 5 years of use.

    Could this be thermal fatigue of the solder?

    It could be when the solder broke there was still a connection but with higher resistance creating heat that melted the wire issulation?

     

    How to resolve?:

    Would it be as simple to recrimp the cable and resolder the terminal?

    Or is there a place to only purchase the terminal?
