How I Wired My CNC E Stop Wrong And How to Avoid It! 🛑

Wiring a CNC Emergency Stop (E-Stop) and Limit Switches can be tricky, and one wrong move can instantly fry your controller board! In this video, I’ll show you exactly how to wire your NC (Normally Closed) E-Stop switch safely, keeping your 5V logic completely isolated from high-voltage components.

We will cover the correct wiring diagrams, how to use a multimeter to double-check your connections before powering up, and how to ensure your CNC chassis is safely grounded. No more "magic smoke"!
