Where to buy more lubricant oil?

Yes, that is absolutely the best possible way to destroy your expensive printer. :bomb:

The answers are in the maintenance wiki.

Carbon Fiber Rods should NEVER be lubricated ! ! !

Properly maintaining carbon fiber rods is straightforward. You can use isopropyl alcohol along with either a lint-free microfiber cloth or lint-free paper towel. In the US, Bounty brand paper towels are in my experience the most lint free. In my earlier career we used it to clean optics. But you can also find blue shop towels with lint-free properties. While the emphasis on lint-free may be excessive, it can be worth it for those who are particularly meticulous. :grin: The most crucial aspect of cleaning carbon fiber is eliminating dust from the shedding fibers and removing any oils or contaminants that could attract carbon fiber dust. That’s why isopropyl alcohol is used; otherwise, water is better than nothing.

If you take nothing away from this thread but this; “Less lube is better than more lube” you will have walked away with some powerful knowledge. This is not a Chevy, this is a piece of precision equipment. Whereas the drive pulleys do not like to be dry, they also deteriorate much faster when they get gunked up with old lube that’s been contaminated by filament dust and the inevitable metal particles from normal wear. That’s why cleaning is more important than lube.
