Is your photo showing only the first layer of the print, or a subsequent one? With photos like this it's always hard to tell what is what, what is expected, etc. so writing that out clearly, and/or showing the model and slicing preview, might help.

@R..GitHubSTOPHELPINGICE Sorry for the poor explanation. I've edited my post with more info and all the pictures are showing the first layer of the print, no further than the first outer wall being printed.

I'm coming back to printing after almost a year of hiatus. Sliced a new model with the latest Cura 5.

I noticed my brim lines are thinning out or under extruding or Z height lowering near the starting point of the print.

It is only happening at this side which is where it finishes a wall/line and proceeds to the next inner wall/line.

At first I thought my bed was massively warped there but I noticed that the first line of the actual body print (outer wall) is totally fine as shown in the picture. I also tried shifting the print to the right but the issue presents itself again.

Does anyone know why this is happening? The Cura flow preview doesn't show any change in flow at this side. And looking at the G-code (labelled as skirt) section.
