how to get rid of artifact on top surface

[str0gg]

Hello,
I am trying to finish setup of V0, I don't know if this is retraction setting or something else.

orbiter v2
Filament prusament asa natural
[firmware_retraction]
24 │ retract_length: 0.6
25 │ retract_speed: 45

After print is being finished this string artifact always appear.

How much tuning have you done? Looks like you have some gaps and first layer is too close.

Have you gone through the Ellis guide?

Yes I did.
First layer is perfect and air tight.


max flow 24mm3/s with 0.4 max out round 25.5.
Travel 450
Accel 9000
Skew 0.12 with correction in place (califlower).
Input shaping calibration done.
advance pressure 0.025

orca slicer
wipe while retracting
retract on layer change
wipe distance 2
retract amount of wipe 100%
nozzle 0.4
I've tuned for this filament. Dimensional correction x100.52 y100.3, temp 250, flow limit 17mm3/s

I've notice that second layer is squish to much but if I change offset then first layer is no longer that ideal.

edit made mistake and use offset for other plate.... First, second and so on is correct on top. Getting back to stringing when print finish nozzle stays in place for a while before getting lifted and move to safe space. Any idea how to get rid of the delay?

flow rate ?

I know what you are looking for but I am not sure I know the answer.
One thing I can think of is have it to a circle Z hop at the end of the print. Might have to manually inject the Gcode for that.
