USB cable +5v Pin-1 isolator https://youtu.be/BQaaRvf3zdA Why I made this: I upgraded my Ender-3 board to BIGTREETECH SKR_Mini_E3_V1.2 board. To use OctoPrint with Raspberry-Pi, it is recommended that the +5v on Pin-1 of USB cable should be isolated before connecting Raspberry-Pi to the Printer. Insert Tool: Use the Insert Tool to guide the Isolator into place as shown in photo and wedge it in place if possible (works sometime).
