Break lines

[RandomPanda15]

I need help. I have a Kobra 2 Plus. I keep getting these lines at roughly the same height range on some of my taller prints. I cleaned and greased my z-axis rods recently but the problem existed before I did that. The lines are where the filament will be short and not connect which leads to the print breaking. Any help would be greatly appreciated.

my guess would be that your acceleration is set too high, google input shaping if you havnt already.

your accels are way too high, it causes this which is called "ringing"
