Stuttering and vertical lines in print
-
Hey guys,
after solving nearly all my other problems, I'm coming to the next - and last - one I hope. When printing bigger parts, I was getting some vertical lines in print, first I thought that would be retract, but it wasn't. When printing longer straight moves, the printer is kind of stuttering. He stops very very short and continues the line. In the picture you can see, that he is doing this only on longer lines in solid bottom layers. In the corners with short ways there is no bloob and no problem. In the solid infill you can see the same patterns (where he stuttered) as in the outlines... I tried different jerks and ACC's, I also decreased the current dramatically...
Maybe someone can help me in here. Have a nice evening!!!

@Phaedrux I'm sorry, forget my config.g
Is there anything else you need for this problem?

Are you using mesh bed compensation? If so, then your very low Z jerk value (M566) is probably causing the stuttering.
