 ### Custom G-code Header and Footer
 
 Add "header" and "footer" text files without extensions in your destination directory to add custom commands. Don't forget to add a new line at the end of these two files.
 
 If no files are detected the default values are :
-- Header : G90 ; Absolute positioning
+- Header : G90 ; Absolute positioningon the
+- Header : G0 Z0 ; Display path inside GRBL Control
 - Footer : G1 X0 Y0 ; Move to X0 Y0
