I am following this video series to add auto-leveling to my Prusa i3. https://youtu.be/awsI9bMndJA
I have printed the parts I need and have the servo and ss-5 endstop in my cart at Amazon. What I need to know is what wiring I need to connect the endstop to the RAMPs board? I bought this printer as a kit and all parts were included so I am learning slowly.
You just need some wires, nothing special about them. You can use any wire that's flexible enough. For the endstop you'll need 2 wires, for the servo (if you need to extend the cable) 3. The connectors on the end are known as dupont connectors.
