Igus Drylin Polymer Bearings on MK3S+ - Pitfalls, Worth it? How to avoid issues.

[@ivyr336]

Seen plenty use the plain bearings. You shouldn't do that. The polymer bearings are designed to be oversized and once they are in their metallic sleeves they reach the correct tolerances. It's because they are soft, any inconsistent load on them from something like a screw as you discovered will deform them. Really not worth using unless you also get sleeves.

Dude this noise on X axis is exactly what I have on my kit built mk4 - Drives me nuts, and everyone is complaining about it

[@jeftesantiago]

I have the same problem with my Mini. I try to replace the bearings to see if it did anything but nothing seems to work.

[@ivyr336]

The mk4 had a bad batch of motors, did you contact support regarding your machine? Could be that you got one of those.

[@montewestlund8195]

you need to use these. they have an aluminum case on the bearing material. makes it harder to compress the bearing. drylin R linear slide bearing RJUM-01

[@BH4x0r]

you can use the aluminium encased ones but they're expensive but those have the correct clamping force as they should be tight fully encased

I had the exact same issue with those on my lulzbot, kinda a big issue
