    Burned Ender3 Crimped Power Connection

    If you've been watching the 3D Printing news on YouTube I'm sure you've heard the news about the Creality Ender3 XT60 power connector issue.

    A batch of the XT60 connectors used between the Power Supply and the Main board have been burning up.
    Seems someone did a very poor job wiring these connectors and its starting to cause some problems for the end users.

    You can see in the attached photo how the connections are crimped on the XT60 from my Ender3.
    What you can't tell in the photo is the both wires on the left side (where the burn spot is starting show) both wires are actually loose in the connectors. You can even see the crimping was done a bit differently on the left side than the right side.

    Just a few days ago I noticed the XT60 connector from the Power Supply to the Main Board on my Ender3 was getting warm after printing for several hours and the following day I noticed the discolored spot on the connector that you can see circled and the connection was even hotter after just a short time printing. I shut off my Ender3 right away and unplugged it just to be safe while I waited for a set of replacement XT60 connectors to arrive.

    If you need to replace the connector you can find them very easily on Amazon if you just search for "XT60 Connector". If you don't have heat shrink tubing make sure you order some with the replacement plugs because you will need it.

    Because these connections are kind of thick and heavy duty I recommend getting a soldering gun to make the replacement. A 100 watt soldering gun (less than $15.00) will quickly heat up the wire and connectors and you won't need to spend minutes with just a small (20 to 25watt) soldering iron trying to get the connections to heat up for a good soldier joint.

    Please make sure to check your Ender3 if you own one.

    If these are “crimped” connection I believe you do NOT want to solder / tin the wires before crimping. Same goes for screw terminals.


      The replacement connectors were meant to be soldered, the original connector was crimped.


        2¢: For high-current connections, crimp and then finish by flowing the wire seat with silver solder.

        It's the twofold approach which I use across the board to prevent interfacial wire/connector resistance increases over time...
