Print Ridges and Imperfection Cleanup
I am printing a large object for 2 days now. Im noticing some large ridges and noticeable imperfections. Curious what settings i should be looking at to ensure these are removed? Is there something obvious Im missing?

Here is the file for reference.

Ive actually got multiple issues with the print. Im just uncertain as to what to improve.
Printed on Prusa XL.
First check, and, if necessary, adjust the belt tensions; https://help.prusa3d.com/article/adjusting-belt-tension-xl_401793
If this doesn't help and especially if your part has a narrow foot print save your project as a .3mf file
Files > Save Project as
Zip the .3mf and post it here. It will contain both your part and your settings for us to diagnose.
Cheerio,

Here is a link to the file. Even compressed its over 10mb.

I tested the frequency app to check tightness. The left side was a little tight. So i loosened it to the correct frequency. I also ran the homing test in that article.
I stopped after about an hr because i saw this massive layer shift.
Your file is locked behind a log-in wall - we probably don't need the whole file, just the section with issues; attach it to your post and it should arrive OK.
The picture is a little out of focus; are the walls very thin? Less than four perimeters thick doesn't offer much stability.
A useful test is to reprint and note whether another layer shift occurs and whether it occurs at the same height.
Cheerio,

Try this. I got it smaller.

Oddly enough, I printed the homing tower again. Everything came out great. But it was immediately after the first print of the homing tower and no changes were made.
why the discrepancy between prints?
40° is too low for the bed temperature, try 60° - 70°.
Grid infill is unlikely to be the best choice, lightening fill will print faster and use less filament or, if you need the stiffness, try cubic.
You have curtailed the curves at the base of the walls, good, but it would still print better with chamfers.
It is rather tall for organic supports - I would be inclined to cut the model at the narrow overhang in the top section and print separately, assemble with a little glue.

Layer shifts like those are usually a result of warping, poor bed adhesion or both - that's why I paid most attention to the base of the model and the print sheet temperature.
Cheerio,
