Y Carriage Base - Bolt loose
I have been chasing a noise which I thought was a stepper motor failing, but the printer has low time. (that is relative I realize)
I found the left Y axis carriage (which mounts the Y axis to the bearing block) had a loose bolt that would rattle like crazy. The carriage is made from two parts, a top and a bottom. From looking at the CAD model, it seems there is a nut in the bottom part of the assembly which is inside a hexagon hole to keep it from turning. The cap screw comes from the top. It seems to me that this nut has come loose, but with the bearing installed you have no access to get to the nut. It is probably laying at the bottom, out of reach for the screw.
Does anyone have a solution? I had to admit it, but tipping the entire thing upside down has crossed my mind. I think I would rather attempt that vs taking the Core XY apart...
Thanks
