I've never ever had a linear bearing get 'gummy' or lock up as I make sure they are oiled constantly, and I just use cheap sewing machine oil. My gripe with them is they do rust I have spent way too much on "stainless" ones but they also rust
Very interesting. What kind of impact does that rust have on the performance of the printer? (Maybe no more printing in the shower?)
