I bought the same tube and I put a bunch in a syringe for easier application which was a good idea and then the tube sat unused for awhile and then next time I opened it a large amount of watery fluid poured out which was unexpected.

How often should you grease up the X, Y and Z axis?

I have been using the same grease, but I find it to be too sticky. Sometimes after cleaning the rods and then greasing them with this grease the stepper motor skips many times and the print goes out of registration. There must be a less sticky grease to do the job. Remember, these steppers are this quiet because they are basically powered to the irreducible minimum. I'm thinking a moly based Type II grease. That is what I am going to try on my next cleaning.

Only when you feel stuck when rods moving.

Thank you Vicky. After each set of prints I'll be checking the movement from now on :D

Well I had some White Lithium Grease (NLGI #2) from Lucas Oil Products in my shop. I am giving it a try. I cleaned off the old Super Lube PTFE grease and used my lithium grease. The very first thing I have noticed is how much easier it it to run the print head around on its tracks. This is not a grease for extreme stress situations, but more mild situations. I believe that is what we have with the printer. Heat is not extreme and pressure is very low. Now drag is low too. My first print is looking very good.

FWIW, I've been running both my N1 and N2 for a year now, both had all the grease of any kind wiped off the shafts from day one. No grease, no oil. Why?
Because the stock linear bushings specifically on the outer ring of rods is made with dry lube graphite inserts and never, ever, ever, ever meant to have grease or oil. The central crossing ones are prelubed ball linear bearings with wipers.

I have no skipped steps, no noises, nothing is wearing out, loose, grinding or any other problem.

Oil and grease defeats the entire purpose of the graphite self lube design. Ever wonder why your grease is black?? That's the graphite.

Again, your printer and everyone else here, this is what are in the XY slider blocks. They cannot be ball linear bearings because the shaft both rotates and the blocks slide on them. Linear ball bearings do not allow rotation.

Manufactures of linear bearings, like the ones we have in the printer head, recommends white lithium grease.
I think Super Lupe is a Brand meant for universal use in the consumer market, without clear specifications.

It would be interesting to hear from Raise3D why they recommend to apply oil/grease on the X/Y rods, when the slide bushings already contain graphite and are supposed to be self-lubricating.
Will oil potentially break down the graphite in the bearings and reduce their expected lifetime? The fact that the grease on the rods is black indicates that graphite is being dissolved by the grease.

FWIW I cleaned all the grease off my rods and its never squeaked (once I got the pulleys aligned)

Given what JetGuy has said, and what you have said, I'd say its worth more than a plug nickel<g>

Good information here. Dry lube graphite ....Makes sense.....Gonna hold off on the grease then 8-)
