Some users may prefer to hide the position updates on the `LIGHTWEIGHT_UI` altogether. This leads to an even less cluttered display (it also saves on SPI traffic and one byte of RAM).
- This status screen uses the ST7920 character generator to greatly reduce SPI traffic and MCU load when updating the status screen.
- Has been tested with the RepRapDiscount Full Graphics Smart Controller but should work with any LCD that uses an ST7920 or fully compatible controller.
