Hi, why you dont use plastic-bushings? With bronze, you need to use oil. Some plastic bushing are mentenance-free and works dry. Like this: Igus Gleitlager DryLin® R - RJ4JP 01-08 (just found on a great internet warehouse with an "A" ;)

No oil needed, the graphite does the self lubrificating job, it's the same that comes with ultimaker, no noise and very smooth.

I was talking to one of my co-workers about this today . He is a millwright , he sugested that you should only use these bushings on chromed rods because of the wear rate of the bushings .

Good to know. I will get PTFE lined sleeve bearings then.

Do you have a link to the correct PTFE lined ones.

Everything you need to know I have posted here:

Just be careful to not short your thermocouples. Mine have been broken and resulted in tool 0 failure (it could have happened from a lot of use though), and during my troubleshooting steps I blew the Max6675 ADC for the thermocouple. Test to make sure thermocouple wires are isolated from heater block after installation using multimeter

Bronze Bushing Upgrade (w/ PTFE) for FF Creator

All info including where to buy bearings is on the instructions page

Yes, where did you get the bearings?

Where did you get the bearings?

Great job on the project remix!! They sure make a difference don't they?

Thank you sir! They really do, can't believe how much "tighter" and quieter the movements are compared to the old bearings. Shot a before/after video demonstrating the noise decrease and its night and day.

Happy Making!

Where is that video you mentioned? Considering making this.

One thing to note is that in the stock bearing video the bearings are installed in the black plastic y-axis holder, while in the bronze comparison video its just one bronze bushing sliding up and down.

Once I installed the bronze bushings into the y-axis holder they did make a little noise but still much less than the stock bearings. I think that this was due to them not being 100% "seated" /aligned with the rod and they were probably binding just a little bit initially. I think that now, after running several prints, if I were to re-test the noise would be much less (pretty sure the bushings have positioned themselves to not bind with the rod).
