Big grooves in all prints

Hi to all,

we just assembled our new K8400, but now we
have problems with grooves on all prints.

Attached you’ll find a picture of a bigger print.

Does anybody has an idea about this issue???

KR, Markus

Just looking at your project it appears that those part start in mid air.
You may need to print with supports.

I have tried it in the past but it was a pain

You’re experiencing a Z wobble. Check the [color=#408040]Wiki [/color]about this.


thx for the wiki-link -> it was really helpful. i read a lot about z wobbling, but didn’t know how to fix it with my k8400.
