Your bed mounting screws are loose.
I am sure you are right, I am just pointing out it can be a problem when they are pretty tight but not tight enough. They are not loose enough to cause print quality problems so I haven’t messed with yet.
Hey. I’ve fixed my issue going through all of the steps in the video and it worked the first time and the second time. Both times for a few weeks. Now it’s happening again and I fixed it again with the video. I just replaced the tape and cleaned everything back there. Now it’s happening again. What could be the issue now?
