I am pretty new to 3D-printing, and I have just finished assembling my Prusa i3 a few days ago.

I finished up basic calibrations, which went fine, but noticed my prints were coming out with a bunch of rough lines on the sides. I looked online, and saw some things about adjusting flow rate, so I took that down from 95 to 90. I am not really sure what else to try right now. I have messed with layer height, which is at 0.2 mm now.

I have double-checked belt tensions and messed around with it, but the belt status seems to be hovering around 267 pretty consistently. I did try loosening it a lot more, but got the around the same, ~270 at max, even when extremely loose. Not sure what the belt tension should be feeling like, but it seems to check out with the guides.

I would appreciate any help or advice.

This is called Layer shifting. You should check belts tension and motor pulleys. It looks like your problem occurs only on the X-axis.

It must have been something with the G-code, or how I was slicing it. I tried printing from the files that were already loaded on the SD card when I got it and it came out much better. I then modeled a cube and sliced it up carefully in PrusaSlicer and it also came out almost perfectly. Thanks to everyone who chimed in, really appreciate it and hope this can help someone else.
