Ender 3 Y Layer Shifting

4

My school started a robotics club this year and one of the teachers gave us an Ender 3 printer to use, they assembled it the year before but never actually used it so it was sitting in their garage, I attempted to print several different objects but all of the larger ones seem to suffer from layer shifting on what seems like the Y axis. I've looked at other threads and tried stuff such as changing the binder clips (add adding more), leveling the bed (again), tightening the belts, moving the print position to a corner, using a different slicer, and reslicing the models which all fail, when I print smaller objects, it prints fine. What could the problem be and what can I do to resolve this? I'm using Cura 4.4 currently.

Failed print:

What it should look like:

Successful print (smaller object):

Edit: I'm also using OctoPrint on a Raspberry Pi for remote control but the issue still occurs when printing from an SD card.

Is the Y belt tight? What are your jerk and acceleration limits set in the slicer? – R.. GitHub STOP HELPING ICE – 2020-01-25T22:39:45.047

@R..GitHubSTOPHELPINGICE Yes, I tightened both the X and Y belt, print jerk is 20mm/s and acceleration is 500mm/s

I'm using the Magic0.20 profile from https://www.chepclub.com/cura-profiles.html (had the same issue with the default profile)

Do the cables of the bed get caught on something? Does the bed run smoothly without the belt? What is the print speed? – 0scar – 2020-01-27T10:54:11.277

Fixed it finally, seems that the X axis was not level. Thank you to everyone who commented.

2Do you have an understanding of how that caused the Y shifting? It would be interesting to hear more – R.. GitHub STOP HELPING ICE – 2020-01-27T22:45:55.470

The entire issue was on the x axis, it didn’t have anything to do with the y axis, the x axis was lower on the right side. My bad for confusing the x and y axis :) – Puyodead1 – 2020-01-28T00:52:59.193
