    • Use a small flat-headed screwdriver, spudger, or similar to pry open the lid enough to be able to get a grip of it and pull straight back and then fold down.

    • The back of the lid has a PCB with cables connecting it to the motherboard inside the unit. While not particularly fragile, do take care so you do not damage the connectors.

  4. Elegoo Mars 3 Limit Switch Replacement, Unplug the cable for the limit switch: étape 3, image 1 de 1

    • In my case the replacement limit switch was delivered already connected to a cable. If you are only replacing the actual switch you can skip this step and instead unplug the opposing end on the switch itself later..

    • Remove the limit switch cable connector in the bottom right corner by pulling it straight out.

    • Be sure to pull the connector, and not the cables!

I've looked everywhere and can't seem to find a place to buy a replacement limit switch. Any suggestions?

I got my replacement directly from Elegoo support. Send them an email, they are very helpful.
