Gaps in Single Wall Tube

[Safety_Lucas 0]

I'm trying to print a small tube with only one wall. The wall and nozzle width are both 0.4mm. The print preview shows gaps and sporadic travels and filament deposition. Instead of laying down just a continuous circular line, the nozzle sporadically moves to different places on the circumference, depositing little bits of filament here and there. The travels between layers seem random and inefficient. and ignore me z-seam preference. When printed, the results look like the preview. I have tried toggling my coasting and z-seam alignment settings but neither affected the preview. Does any one know how to fix this?

I would reduce the line width to 0,32mm and see how Cura slices it.

You could also model it as a solid cylinder and then tell it to use a single wall, 0% infill, and 0 top layers (and 0 bottom if that is open too.
