; If downloading this file from the "wiki" page you may 
;  need to rename the file to remove the .txt file extension.
; The file extension needs to end with .gcode instead of .txt
;
; Invert Y-Axis 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 Select Mini
;
; This file is much longer than it needs to be but is like this to 
;  show what is going on.
;
; Lines with only a semicolon are for making line separations only.
;
; 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.
;
;
; BEGIN
M107 ; turn fan off in case it was already on
