Invert extruder motor direction?

claustro

I know it is a dumb question , and I could simply turn the motor connector 180 degree, but I would like to understand what I am doing wrong.
[c];M575 P1 B57600 S1 ; Comms parameters for PanelDue; Machine configuration
M569 P0 S0 ; Drive 0 goes forwards (change to S0 to reverse it)
M569 P1 S0 ; Drive 1 goes forwards. (Change if motor goes wrong way. Or just turn the motor connection 180 degrees around..)
M569 P2 S0 ; Drive 2 goes forwards
M569 P3 S1 ; Drive 3 goes forwards
M569 P4 S1 ; Drive 4 goes forwards
M574 X1 Y2 Z0 S0 ; set endstop configuration (X1 is at MIN end. Y2 is at MAX end. (active high switch = S1, active low switch= S0)
M667 S1 ; set CoreXY mode[/c]

I tryed to change M569 P0 S0 to M569 P0 S1 with no luck I tried changing "S " at all the drive with no luck.
Can someona tell me what I am missing?

So the drives are mapped like this by default:
0 = X
1 = Y
2 = Z
3 = E0
4 = E1 etc

Assuming you are referring to extruder 0, you should change the line:

[[language]]
M569 P3 S1

To

[[language]]
M569 P3 S0
