    When we bought our ender 3 pro this limit switch was broken, causing the auto home to malfunction.

    We bought a replacement limit switch, but need a little help with instructions on how to best remove the left mount so we can replace the limit switch.

    Or, if there’s another way to replace this limit switch, any points in the right direction would be greatly appreciated 🙂



  • Hi,

    You need to remove the QR sticker to reveal 4 screws holding the plastic housing and stepper in place. Once removed you will find 2 screws holding the switch in place.
