Extruder E0 changes direction on Speed change

[SetraX]

Hello,

this is my load MACRO....
and it changes direction just because of ???

; Load filament
T0
M109 S200 ; set heater/nozzle target temperatuer and wait until reached
M116 ; Wait for the temperatures to be reached

G1 E10 F600 ; Feed 10mm of filament at 600mm/min
G1 E100 F3000 ; Feed 120mm of filament at 3000mm/min
G4 P2000 ; Wait one second

!!! Crazyness starts here... changes direction here and does other crazy stuff so that my filament just lands where it started 1mm after extruder E0 motor

And the best part of it... it started when I tried to adjust the command to 20mm....

G1 E20 F300 ; Feed 20mm of filament at 300mm/min
G1 E5 F150 ; Feed 20mm of filament at 300mm/min
M400 ; Wait for moves to complete
G1 E-2 F300 ; Retract 2mm of filament at 1800mm/min

;M292 ; Hide the message
;M106 S0 ; turn off cooling fan
M104 S0 ; set extruder temperature to 0C
;M140 S0 ; set bed temperature to 0C

Anybody any ideas what I do wrong?

All the best

@SetraX Well done !!! I screwed up with relative and absolute positioning.
M82 ... I figured out from some partfiles sets to absolute positioning
M83 ... sets the relative position as I need it ...SOLVED
