M562 - Invert Stepper Motor Direction


If the Mini Delta is trying to home in the wrong direction then you may need to invert the XYZ motor direction

Extruder

M562 E                ;Inverts Extruder/Feeder Mechanism motor direction
M500                  ;Saves changes to EEPROM
Reboot printer to complete the process (turn off, then on)

XYZ

M562 XYZ              ;Inverts X, Y, and Z motor direction
M500                  ;Saves changes to EEPROM
Reboot printer to complete the process (turn off, then on)

M562 E

invert_extruder.gcode
; G-Code generated by Matthew Upp of GigDigit.com
;
; 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.)
; 
;
; BEGIN
M107 ; turn fan off in case it was already on

Each axis can be inverted separately if needed for whatever reason.

X-Axis

M562 X                ;Inverts X-Axis motor direction
M500                  ;Saves changes to EEPROM
Reboot printer to complete the process (turn off, then on)

Y-Axis

M562 Y                ;Inverts Y-Axis motor direction
M500                  ;Saves changes to EEPROM
Reboot printer to complete the process (turn off, then on)

Z-Axis

M562 Z                ;Inverts Z-Axis motor direction
M500                  ;Saves changes to EEPROM
Reboot printer to complete the process (turn off, then on)
