Prusa MK3S+ Maintenance / Service for 3D Printing Farm 

Sponge, I purchased them from amazon.

@@mariuschirita2017 thanks what kind of sponge? The ones I have tries have degraded over time.

@@renk872 Never changed them, I try to turn them around a few times. I just replace the whole filter when they are done.

Ideally monthly, but I don't really have the time to do it monthly, sometimes every 2 months. Cleaning and lubricating the rods is quite important and this can be done more often.

I use the lubricant that comes in the box with Prusa printers. Probably any lube would do it . I did read good things about lithium lube but never tried it. The cleaning filament is not very good for cold pulls , it sticks to well on the nozzle and it breaks when you try to pull it out. I found PLA+ does the best job for me. Some people do it with nylon but I never tried it.

@@mariuschirita2017 My Prusa original MK3 didn’t come with any Lube. Been using 3 in 1 oil

@@partsdave8943 I prefer thicker grease, I think it holds for longer. Just my opinion. There are many videos on youtube about grease for 3d printers.

I tried PETG but found PLA+ better. I found PLA+ works very well with the cleaning filament and always had successful cold pulls with it.

Yes, it is pushing some lube to the ends, but if you evenly spread the grease along the rod, the balls inside the bearings are definitely collecting a lot. The barrel ends diameter is higher than the rod's. That is the reason I keep spreading the grease a few times while moving the bed and the hotend. This worked very well for me. Some of my printers are almost 3 years old, printing 24/7 and they print like day 1.

@@mariuschirita2017 certainly that bed sheet looks like new!

@@NigelTolley that is the newest printer, a few months old. The older printers are on the bottom row. Old down, new up 😉
