Are the wheels on the Y-Axis supposed to be tight enough that they grip the horizontal bar? I'm having issues with the layers of my prints shifting, sometimes significantly. I was having significant issues with layer shifting, but I tightened my wheels on the Y-Axis and the issue has lessened significantly (at least after the first few layers). Has anyone else had issues like this? I'm certain that my flex-plate is not shifting, as I put down a piece of tape underneath and marked the tape so I could check if the flex-plate moved (which it didn't).
Sometimes my Y-Axis will have trouble moving, and I'm not sure if the eccentric nuts are too tight, or if the belt is too tight, or what.
(P.S. I'm not having issues with the X-Axis moving too much or too little as the layers are only shifted in the Y-Direction.)
