Anet A8 - Gaps at circles

[Jan19998]

Found out that the gaps only appear on the right of the circles and only at a height of up to 5mm. Otherwise they aren't a thing.

different filament ?
could be caused by inconsistent thickness in the filament I suppose.

You really don't see that very often these days - but it's possible.

Yes, I've tried different filament. I did a E steps calibration. Although I could not get it to extrude 100 mm, Somehow it improved the undextrusion issue. Just printed a calibration cube with zero gaps. But now the cube is .5 mm off in the dimensions. I might have slight overextrusion now. But at least the gap/holes are gone!

But the problem isn't gone.

The holes problem is gone as far as I can tell. Despite the overextrusion, I am much happier about my prints.

I mean the problem i have with my prints.

I think it's a mechanical problem but i have no idea what it could be.

Maybe someone has an idea?

Looks like that at the moment.
