I have seem to recently developed some wobble along the Y-Axis. The bottom X+ side bearing on the bottom isn’t making contact with the support tube. This isn’t a new machine, and has made plenty of cuts before. Is there some bolt that I can tighten to help get it back in place? I don’t want to just indiscriminately start tightening/loosening things haha.
I think it is the vertical bolt, in the left side of your video, in the orange part. When that closes up, it should pull the bearings in closer to the tube.
Move it sparingly. Old plastic may crack under new tension. You just want it closed enough that the bearings all touch.
That helped, for a generous definition of sparingly. I tightened up other, similar joints to help tighten them up against the rails which did help and it’s about 95% of where it was originally.
If you’re still trying to firm things up, it might be worth taking a few areas apart and checking for hidden cracking. That’s been reported here in the forums in the past.
