No extrusion at last part of layer

[AndersK 59]

Material flow stops close to layer end and I cant find settings in Cura that might do this.

Looks like excessive coasting but that is not enabled.

Width are roughly 4-5 mm

Smart Z-seam hiding is enabled so I get this at mixed locations, both inner and outer wall

 

Any hints?

What does the g-code look like? At first glance i would also blame coasting.

Looking at second picture and third layer (Z1,9) it seem to start at X75,762 and end at the same if I read the file correct. Gap is in the X-axis

I assume the last G0 movement is wiping the outer wall

Same part but arc welder enabled makes the code easier to read to me, knowing what is circular and straight motion.

However, I did not save this as a 3mf file and might have moved the model so X and Y positions cant be compared but it seems to do the same:
