Help needed: layer shifting

[Roberts_Clif]

Aha ok I'm not surprised by this suggestion. Something I forgot to mention is that the bearings also make various horrible sounds whenever the printer moves left of the midway point along the x axis. You could very well be onto something here. I'll have to get one of these ultrasonic cleaner things though. Will any work? they seem to vary in price quite a bit.Ughhh not looking forward to removing the bearings again, its a big job.... but needs must.

You can clean the bearing in any solvent or using plain alcohol, alcohol is what I use to clean my bearings in a shallow dish.

I also use canned solvent or de-greaser.
