## Printer firmware layer data adquisiton
1. On gcode, when machine firmware detects M6054, it goes to the layer table at layer x index given by the command and gets the layer data to buffer the image
1. Machine firmware detects `M6054 i` gcode command
2. Goes to the layer definition table at the `i` index given by the `M6054` command
3. Gets the image address and jumps to it
4. Start to read and buffer the image to the LCD
**Note:** Printer only continue to execute the next gcode command after the image is displayed/buffered.
When using a sencond board to display the image, it must send a OK back in order to resume the gcode execution.
