Very interesting.  I don't really have this issue, but I'm going to give it a try anyway.

If you did the epoxy/ship on the z plate I think it basically does the same thing. the additional mass makes the bed less likely to move back and forth for the wobble.

Re: DAVINCI 1.0 Z-AXIS Counter Weight - FIXES Z Friction

My rods got messed up over time. The Z axis would stick preventing micro travel on layer change.  Constant use for a year, caught my cat napping on the print bed more then once. I've also been some what rough with this printer. For the longest time I used acetone slurry and frequently had parts that needed excessive force to free. It may or may not have contributed to the wear.

Had way to much trouble trying to get stock parts re-aligned. I was starting to wonder if the rods were bent or the bushings were shot. I can see now how epoxy would help keep the bed from lifting out, didn't think of that. I duct taped random weight to the back so I could print new supports in a last ditch effort. It worked so well I opted to make a proper counter weight and left the stock supports as is.

Let me know if it helps anyone else, thanks.
