First Service of Bambu Lab P1S — My Experience

I printed 30kg for PrintArmy and a couple of kg for myself. The printer is about 3 months old. I lubricated the Z-axis guides after about 15kg. I used the packets from the Bambu Lab kit. For the Z-axis, you need to use the Grease packet. For the 30kg, I decided to clean and lubricate everything necessary. Before that, I watched a few popular tutorials on YouTube. Specifically: Overall, they are decent videos, but there are nuances. For example, in one video, the author applies too much Grease. I followed his lead. Then, when lowering the bed, I realized that excess from the axis would be squeezed out and the extra lubrication needed to be discarded.

The miracle of assembly - I removed the excess lubrication. And for beginners (like me), it may seem that something went wrong.

In fact, everything is quite simple. We vacuum (need to remove debris so that nothing gets stuck during wiping), wipe with a dry cloth (lint-free), and vacuum again. After that, we start lubricating. Here is link to the official documentation (tutorial for the p1 series). We vacuum

We need to clean all fans (coolers) from dust and generally everything you see. After the first run - we wipe with a cloth and vacuum again. In P1S, the ventilation is stronger than in the open P1P (according to comments), so dust accumulates more intensively there. Especially on the rear and bottom coolers.

It's hard to reach with just a vacuum cleaner — next time I will definitely get a can of compressed air, because blowing it manually is not an option 😅 We lubricate

I started with the Idler Pulley. These holes are at the back of the printer. They pull the belts back and forth. Here is the translation of the official documentation:

In all videos, they say that Super Lube should not get on the belt. I used a syringe and applied a drop on the top and bottom of the bearing. My printer is in a separate room, and I don't mind squeaks or anything like that, but better safe than sorry. Z-axis Lead Screws

First, you need to wipe these screws. The cloth will have to be thrown away afterward. P1S has three lead screws. Left, right, and in the middle of the back wall.

Here is a visual example of what I would not recommend doing. You should lubricate with your finger in gloves just enough to leave some in the grooves of the thread. Otherwise, it will look like this:

I had to wipe off the excess and throw it away. Considering the price of the lubricant, it's not very pleasant. But experience is experience. I used this Grease:

Y-axis and Z-axis Linear Rods

These rods need to be wiped very carefully with a cloth with a drop of Super Lube 52004 on both sides. And that's it. The second time this will take me not much time. After that, I replaced the sock on the nozzle and installed an additional cleaner for it. But there will be a separate post about that.
