Should I lube my Mini?

What, if anything, should be lubed on my Mini and what should I use for lube?

Perfect, thank you.

Those bearings may be intended as self lubricating but unless you keep them scrupulously clean they will get contaminated and, ultimately, noisy. That seems to be a one-way road, too. The stainless shafts on our Mini apparently got some dust on them and despite repeated cleanings, they now “groan” when the position and speed are just right. I suspect some dust/whatever got into the bearings, and no amount of shaft cleaning is getting it back out.

Interesting. Both my lulzbots will make sea lion-type sounds under just the right conditions.
