Due to my Linear Bearings wearing out, my X carriage is doing the rocking back and forth motion.
I started to look around for solutions and came across Printable Linear Bearings on Thingiverse . Which brings me to asking if any one has given this a shot? They say to use White Lithium Grease to reduce the friction and to also print the Linear Bearings with PLA.
I was also thinking about giving this other idea a shot.

But was thinking that from the Pulleys, that maybe the Pulleys would wear out the smooth rods like metal ball bearings.
So, if any one could give a shout out about either one or maybe came across something better to use as a Linear Bearing. Any helpful info would be appreciated.
Love it! That second idea, using the metal bearings…VERY VERY VERY COOL. All signs point to it working man, and sure it will wear over time but not as quickly as plastic!! thanks for sharing, this has me thinking now…
The IGUS bearings take a while to wear- don’t get me wrong they are designed to wear, but that wear occurs when the bearings wear onto the rods to reduce friction: http://www.igus.com/wpck/3549/drylin_intro
If there’s a bit of movement on an axis you can move the bearing holders closer together to take up any extra room, just loosen the screws holding the bearing holders, move the bearing holder closer to the midline of that axis and tighten back down. As long as movement is still easy and smooth it should be all that’s required.
