All was fine yesterday and now i get no response out of my machine. Connect to GRBL and the USB LED starts flashing red. Any ideas of what it could be?
Mine flashes red when its connected. What does the serial console say? Any errors? Do your motors have power? It doesnt look like it.
On the board, there are LEDS next to each axis. They are usually on when there is power to the motors. Based on your picture, it looks like there is no power to your motors, which would explain why the machine isnt moving. Do your motors have power? The screenshot is really hard to see, but it appears that grbl panel is connected and idle. Look for error messages in the Status box (the box under the green box that says IDLE)
