Build table vibration

My Taz4 has developed a vibration when the build table moves away from the operator. It’s bad enough I feel it in the work table. I’m suspecting a bushing issue. Is there a recommended lube or fix?

I assume you mean the Y-axis?

You don’t want to lubricate the bearings as they are self-lubricating. Lube will just attract debris and could make your problem worse.

You could try just wiping the shafts with a clean, dry, lint-free cloth and see if that helps. If it is only happening when it moves away from you (in only one direction on the y-axis. I would suspect you have accumulated dirt, dust, debris, maybe even a chuck or string of plastic on one side of your bearings. Give it a good clean.
