        • ESP_OLM3_V210_230223
        Download and unzip this file please
        Extract zip file into desktop.
        Inside it, you will see a ESP_OLM3_2010.bin file

        Now with your machine connected via USB to your computer.
        Tap the reset button once to turn off your ORTUR

        Then do this sequence carefully:

        PRESS and hold the reset button on the back of the motherboard. Do not release
        Count 3 seconds
        PRESS also and hold the power button. Do not release
        Count to 3 seconds
        Release Reset Button
        Count 1 second
        Release Power Button

        Now your computer will show an ORTUR UPDATE drive – almost as if you had inserted a USB thumb drive
        Copy the bin file we extracted earlier into the drive and allow the machine to do its update operation
        It will take 30-60 seconds and the machine will home again

        Reconnect to LightBurn or LaserGRBL – in the console type where it says (Type commands here) or (Type GCode here)
        The machine will respond with
        [MSG: restoring defaults]

        At this point, you should be ready to use the device.
        Note: your wifi settings if you had them will need to be done again
