displacement y axis

I have a problem that with large prints, there are a few small displacements in the Y axis. The X axis is all right.

Thank you very much for your advice

RE: displacement y axis

There are artifacts that happen when the layer print time falls below certain thresholds.  This may be what's happening.  The effect may be a minor bulge, or a small wall shift, or just a texture change due to perimeter print speeds, or even a directional change.

Turning down one of the slice cooling options can help, as can reducing print perimeter speeds, or even adding a perimeter.  There are many reasons for the artifacts, and many solutions.  No single catch-all to be offered.

Here's a fairly deep dive into the subject: https://forum.prusa3d.com/forum/original-prusa-i3-mk3s-mk3-how-do-i-print-this-printing-help/buldge-when-print-reaches-solid-layers/

But, I came away with slowing perimeters to improve "sheen" consistency on glittery PLA, and reducing unexpected speed changes do to cooling settings.  I even went lower than 6 to get the best results on test cases, and set perimeters to 20 mm/s when I was using Prusament Mystic Brown.

Thanks for the tip. I will try. It's just weird that when I used GCODE directly from Prusa and they have it according to the photos have OK.

So if it's not something hardware

Close inspection of the post show the same artifacts on his parts.
