One of the bed linear bearings (y axis?) is failing on one of my printers. It makes a bad grinding noise, and leaving dark streaks on the steel rod. So for now I've stopped using it because I don't want to mar the rod. Anycubic customer service is great and they are sending me new parts.
But, I also looked into getting the Igus polymer bearings, and seeing a lot of mixed reviews. Have any of you guys used the Igus bearings on your printer? Success? Too much play? I'd like to try them out because the linear ball bearings are noisy and sound kinda gritty.
I tried them on my i3 clone (wanhao) and didn't like them because they did seem to allow a little play, though I didn't see any artifacts. Your rods also have to be perfectly parallel or they drag. I'd suggest splurging a bit on the misumi brand bearings... they cut my noise down a good bit and got rid of some small artifacts from the cheapo brand ones that came on the printer. I'm not sure exactly what printer you have, but oddly when I switched to longer bearings it actually ran quieter too.
They seem to be one of those things that people either love or hate, with little middle ground.
Fwiw, I just tossed some cheap lm8luu bearings on my Y axis (Wanhao Di3) when it started to make noise. It's now making a *different* noise (two years later) but prints fine.
It's for my anycubic i3 mega, an i3 clone.
I went ahead and grabbed some of the Igus bearings, $10 for 10 on Amazon was hard to argue with. We'll see how it goes.
If they don't work out I'll just bite the bullet and get the nice misumi ones. Thanks for the input fellas!
Did you do anything with this, yet?
I've got the igus bearings now, came in the mail the other day. I'll post up when I get around to trying them out.
