Surface marks on the outer layer

[asykesey 3]

Greetings- this has occurred a few times, but never this bad. it's caused from when the printhead moves from the second layer out to the first layer and back the other way, each time it leaves a small mark...is there a setting in cura to prevent this or to decide where the marks go? as the back of the print is coming out fine, but the front face which will be seen is having the issues.

(printed with 0.8 nozzle at 0.4 layer height- never printed at 0.4 before, possible cause? )

Hi and welcome to the forums.

Never printed with that combination either...

But you can place the Z-Seam manually or try to let cura hide it on the back of the model. Check out the "Z-Seam Alignment" option:

I was unaware of this feature, cheers! unfortunately though, i do not get the 'user specified' option, only 'back' 'shortest' and 'random' any idea why that may be?

If you select it, you can specify the x/y coordinates for the seam. But good luck finding the right coordinates. It is not intuitive at all (let alone documented).
