How to remove retraction that happens at walls?

[sycamore361 0]

I have a 3 extended printer. So far I've tried to disable any retraction that is possible in Cura's settings, and it turns out that all the major retraction disappears. The only part I don't understand is retraction still happens at walls:

 

1. Filament is retracted a few mm back when printing an inner wall

2. After the inner wall is finished, filament is pushed forward a little before it prints the outer wall

3. After the outer wall is finished, filament is pushed forward a little again before it starts to print the infills

 

 

Note that my model has several loops of walls on the same layer, not sure if that has anything to do with the retraction. See image attached.

 

I'd rather have the filament not retracted at all despite the side effects that might cause. Any idea how I can disable it?

Do you have combing enabled?  Combing enabled will do fewer retractions.  Combing disabled will do more.

 

When you go to PREVIEW mode set the mode so it shows moves in blue.  Dark blue is non-retracting moves.  Light blue is retraction moves.  Are you seeing light blue moves?

i think i find the answer, by enabling coasting that tiny bit of retraction is gone

I was thinking of coasting but coasting doesn't retract so I didn't mention it.  It should have the dark blue line (no retraction).  It also doesn't extrude.  So instead I mentioned about the colors to see if it's really retracting (I think it wasn't retracting).

something weird about the Preview mode is that for some reason it only shows the model in translucent grey, but not the paths of printing... it used to not be like this. paths of printing only appears if i click the "play" button at the bottom

If you are in compatibility mode (the preview shows flat lines instead of 3D sausage shaped lines) then one of the visibility settings is "Top Layer Only".  That will leave a lot of the model gray as the slices just isn't being shown.

found out what the issue is... the layer was not turned on lol

 

thank you both for commenting!
