Super Lube 92003 Silicone Lubricating Grease with PTFE, 3 oz Tube, Translucent White

Bambu’s wiki pages say 52004 for the oil applications and 92003 for the grease ones. https://a.co/d/0eqV4K2Yhttps://a.co/d/08ykz8IV

I just did a ton of research on this... For the grease it's straight from Bambu's Recommendations 92003https://www.amazon.com/Super-Lube-92003-Lubricating-Translucent/dp/B0081JE0OO/ref=sr_1_3 Also for grease, they recommend LucasOil White Lithium NLGI #2:https://www.amazon.com/gp/product/B06XY6QKS7/ref=ewc_pr_img_1?smid=A17BZOLZKLWVN9&psc=1 For the Oil, I went with 52004. For me the difference was that 52004 doesn't have PTFE, and is actually mentioned in earlier bambu documentation as a higher quality oil on this page: https://wiki.bambulab.com/en/x1/maintenance/basic-maintenance it's harder to find 52004, but place like Grainger carries it (I picked it up in store locally! but you can order it too)https://www.grainger.com/product/SUPER-LUBE-Hydraulic-Oil-Synthetic-Lightweight-45NA65 Also it's on amazon but you have to click "all buying options":https://www.amazon.com/Super-Lube-52004-Lightweight-Translucent/dp/B00175VGUA/ref=sr_1_2

The X-axis rods have graphite bearings, so they don't need grease. In fact, the grease actually damages them. The residue you are seeing is the graphite wearing off the bearings. I do find that lubricating the X-axis rods helps, but I do not use grease. I use Super Lube No. 51004. It is a thin oil with syncolon suspended in it. It will NOT damage the graphite bearings, but it will lubricate the rods and smooth out the movement. Edit: To fix you issues, you should thoroughly clean the rods with IPA, then apply a thin layer of the Super Lube No. 51004. After application, you should rerun the input shaper calibration. Also, for the Y-axis and Z-axis I use Super Lube No. 92003. It is a thicker grease with the same Syncolon particles, and it works great for the non-graphite bearings.
