    Sorry for my late reply! I often don't get a notification when a question is asked ?!
    I did that with my CNC machine ;) For the display I used a 45-degree bit to get a nice bevel.

    I bought a Meanwell 5V power supply. I NEVER mess with chinese power supplies because they are dangerous. This power supply has the advantage that you can set the voltage a bit so I set it to 5.1V to count for loss in the 7m wire.

    Great idea to add a LCD display! I'm not much of a programmer so I'd have to dive in and try this but my time does no allow for that...

    Did you try to update the display before/after the button action?

    As you have seen, there is a keyboard.begin and keyboard.release. DO NOT put any other code in between those. So I would expect not any problem if you perform other actions before keyboard.begin or after keyboard.release?!

    void press_F2()
    {
    Keyboard.begin();
    Keyboard.press(KEY_F2);
    delay(100);
    Keyboard.releaseAll();

    Other than that I cannot come up with any suggestions...
    I think other more experienced programmers on the Arduino forum CAN help you out...

    I do hope you'll succeed, don't give up on this! ;) I spent 95% of my time getting rid of errors but at the end it did work...
