Open the Download / stream menu and pick USB or Wi-Fi. For USB, use a Chromium browser (Chrome/Edge/Opera/Arc/Brave — Firefox/Safari lack WebSerial), plug in the ESP32, choose the serial port, and the tool streams the G-code line by line. For Wi-Fi, connect to your FluidNC controller's WebSocket over your network and stream wirelessly.
Make sure your G-code profile/axis mapping matches your firmware first (the output letters must match your config). Both transports are in beta and carry a BETA badge until bench-tested against more hardware, so for first runs, watch the machine closely and keep your E-stop handy. Prefer offline? Just download the G-code and run it from an SD card.
