In this video, we will take you through the process of adding limit switches to the Scuplfun S9 (or similar diode laser). We will cover the physical installation, wiring, and configuring with GRBL firmware. We will also cover how to set up a macro to easily enable the limit switches each time you connect to LightBurn. In a followup video, we will cover the process of flashing clean GRBL onto the controller for a more permanent solution.
