UPDATE: Another way to fix this in Cura is turning the "Combing Mode" off but that increase the time speed over 30%

This video is about a common problem with the infill (As well on the wall but usually not noticeable) on FDM 3D printed objects. And how it can be solved or at least minimized.
The problem can be described as that the infill lines do not attach to the walls at the printing starting point of the line. That can cause some structural problems in some pieces.
In this video I describe a way to set up the slicer in order to minimize this issue.

There is a plugin for Cura that fix this issue; "Scalable Extra Prime" https://github.com/Pheneeny/CuraPlugin-ScalableExtraPrime
It linearly scales the amount of extra prime after a travel based on the distance that was traveled.
I think it should be added to every slicer. Because this problem becomes really serious when using leaking volcano hotends and printing big parts that the head has to make big travel distances.
But that plugin is not updated (as for 4/25/2020) to actual Cura versions so can not be used.
