; Invert Extruder Motor Direction
;
; This gcode file will work with the following 3D printers:
; Malyan - M100, M200, M300, M310, M320, MA10, MA10 Mini
; Monoprice - MP10, MP10 Mini, MP Mini Delta, MP Select Mini
;
;
; This file is much longer than it needs to be but is like this to 
; show what is going on.
;
; If when "printing" this file it does not show as completed on the 
; display but the fan pulsed on and off a few times then the invert 
; command was successfully ran and saved. You can turn the printer 
; off and on to make sure the setting was saved.
;
; Lines with only a semicolon are for making line separations only.
; Please add a blank line to the end of the file while editing.
; DokuWiki Code Blocks deletes blank lines at the end of the block but 
; g-code files typically end with a single blank line at the end. 
; (It is not a big deal if you don't add the blank line.)
