Thanks for the reply. Double checked that and messed around with it, but it 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.

@notkvnchn - Please add any additional information to your question, so that all of the information is in one place. Actually I have just added it for you, this time.

@notkvnchn Have you checked if the gear on X-axis motor is tightened correctly? Both grub screws need to be tight, one of them has to be tightened against the flat part of the motor shaft.

I tried following the steps, though most of it (like aligning the screw with the flat part of the shaft) was already done. Calibration cube is still printing out pretty bad though, not sure what else to try.

It looks like these are different issues now. It doesn't look like layer shifting anymore. Now, it has signs of under-extrusion and over-heating issues, according to the photo with calibration cube. What calibrations have you already made?

I redid xyz, lowered the tension screw for the extruded thing (not sure what the proper term is) and messed with belt tension a bit, but it’s basically where I started.

What material are you using? And with what temperature. Do extruder E-steps calibration first if you haven't already.

@kosteklvp the weirdest thing happened today. I clicked on some random gcode that was already on the sd card when I got it, and it magically printed out an almost perfect tree frog (minus a weak point on the legs.) I then printed out a benchy from that was also on the sd card, and it also almost went perfect, though it came off the printed in the final 15 minutes. Quality of these prints were completely opposite of what I had experienced before, with much less noticeable irregularities. I also modeled a 20mm cube, sliced it up in prusa again, and it worked perfect. will update original post.

Considered adding it as an answer, instead of an update to the question. It can help someone in the future.

# Prints coming out with jagged lines on the sides, rough edges

(Asked by: username_0 on 2023-01-01)

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](https://help.prusa3d.com/article/layer-shifting_2020)**. You should check belts tension and motor pulleys. It looks like your problem occurs only on the [X-axis](https://help.prusa3d.com/article/adjusting-belt-tension-mk3-s_112380#x-axis-belt).
