Problem with G1 command

Hello there
So the problem is as follows:
when I manually send a G1 command like (G1 F200 E1) the printer extrudes nice and slow but 'retracts' to the starting position very fast.
Anytime I extrude a certain length of filament, the extruder retracts the same length it seems.
What could be the cause and how can I stop that from happening?

For more Info on how I initialise the Printer:
M104 S230
M105
M109 S230
M82
G28
G92 E0
G1 F200 E3
G92 E0
G92 E0
G92 E0

There is nothing that should be able to cause this

Send a M114 before and after the G1 E move, see where the printer think it is afterwards

Good Idea,
I will answer when I'm done.

>>> M114
X:0.00 Y:0.00 Z:0.00 E:5.00 Count X:0 Y:0 Z:0

>>> G1 E1

>>> M114
X:0.00 Y:0.00 Z:0.00 E:5.00 Count X:0 Y:0 Z:0

So as you can see the extruder definetly drives back to that position...

What am I doing wrong?

EDIT: I found out that if I load a whole .gcode-file, the extruder will print normally. But if I stop it, it will revert back to position E5. Is this some preset where the printer will drive back to a 'start' position, when he thinks hes done?

What firmware does your printer use?

---

Large delta printer [miscsolutions.wordpress.com], E3D tool changer, Robotdigg SCARA printer, Crane Quad and Ormerod

Disclosure: I design Duet electronics and work on RepRapFirmware, [duet3d.com].

So I have a Ramps1.4 on top of Arduino Mega. The firmware is Marlin 2.0.x.
On my PC I use python with the pyserial-library.

With the ramps-board I controll the Extruder and a fan and the temerature. No x,y,z-axis. Could that be part of the problem?

On further testing I somewhat replicated the problem: When I send consecutive G1 E.. commands the extruder works just fine. But as soon as I stop sending the G1 commands it retracts to the position E5..
Is this a "the print is finished, revert to home position" kind of deal?

Does anybody have an answer?

please attach your config files.

Here they are

Using your configs, I cannot replicate this issue

First I M302 P1 , as im testing without a hotend
and this allows cold extrusion

M114
> X:0.00 Y:0.00 Z:0.00 E:0.00 Count X:0 Y:0 Z:0

G1 E1
M114
> X:0.00 Y:0.00 Z:0.00 E:1.00 Count X:0 Y:0 Z:0

G1 E1
M114
> X:0.00 Y:0.00 Z:0.00 E:1.00 Count X:0 Y:0 Z:0

So Extruder is in absolute position mode, so G1 E1 means go to absolute position E1, which is fine

G91 set to relative mode

G1 E1
M114
> X:0.00 Y:0.00 Z:0.00 E:2.00 Count X:0 Y:0 Z:0

G1 E1
M114
> X:0.00 Y:0.00 Z:0.00 E:3.00 Count X:0 Y:0 Z:0
