layer barcode :)

Hi all,
these were printed no infill, vertically and with 2 shells
Speed was 25mm/sec I think

What would you make of these layer shifts? They should not be from ringing, since I also notice slight ringing besides…
Maybe something mechanical?

…aaaand here’s a sexy picture like one of your french girls :slight_smile:

That looks like z wobble to me. You might want to check out the anti wobble project.
