X-axis goes up at the far right
This is my first personal 3D printer. My only other 3D printer knowledge is all online and using a Ender 3 V3 SE that a family member owns. I bought it off someone on FB marketplace as a working unit, so it was not assembled by me.
Everything works from what I can tell. All 3 axis move, filament goes through and melts just fine, and the bed heats. I put a new tip on (the one that came with it was too clogged), and started leveling the bed. After checking the results, I did notice that it was still off even after messing with it for 30+ minutes. I decided to use the move controls to see what was wrong.
I noticed that when it gets closer to the right side of the X-axis, it suddenly goes up higher than normal. This made the bed not able to be leveled correctly. I did mess with the tension, and it doesn't seem to help? I didn't tension it too much, since it felt like it was gonna break before getting to the half way point.
I don't see anything that could be wrong, but I could also be missing something as I wouldn't call myself very knowledgeable.
