Snapmaker 2.0 A350T lead screw greasing to reduce the squeaking noise in Y-axis movement

Snapmaker 2.0

Hello Everyone,
Appreciate your time in helping us out!
We have a Snapmaker 2.0 A350T which is 2 years old.
This year we have added a Dual extrusion module and a quick swap kit to our machine.

We have been using this machine regularly for short(6hrs) and long (24hrs) prints. After using it for 2 months continuously we observed that there,

  1. Is a loud squeaking sound from the Y-axis movement as it goes backwards during print

  2. But when we move the bed in Jog mode there is none.

  3. So we have been lubricating all the lead screws after every 2 to 3 months using a lithium-based grease, (picture uploaded in the post)

  4. But we have observed that once the machine completed 1 year it has been making the loud squeaking sound frequently even after lubricating the sounds reappear within a month.

Can anyone please help us out,

Whether we are using the right type and quality of grease
Also what is the ideal time to grease all the lead screws also can anyone share a reference video about greasing the Snapmaker A350T

Thank you : )

Have a look here:

Is it squeeking at any speed (-change/reverse move, I guess)?

Did you check your sliders? If not, do so: https://support.snapmaker.com/hc/en-us/articles/1500000110341-What-should-I-do-when-the-slider-of-the-Linear-Module-comes-loose

Watch the end stop switches - they can easily be damaged when re-assembilng the module.

Could just be dirty dust covers (the metal strips on the linear modules).

  1. yes, the loud sound is at all the speeds and mostly when the bed moves backwards.
  2. Also an important thing to note is that when the bed moves to the home position towards the user side there is no sound.
  3. Also there isn’t any sound when home all axes

  1. I have been greasing the lead screws by opening up the entire linear module getting the lead screw out and putting it back in that process I reassemble the sliders(steel flexible strip) carefully but after 2 years the strip doesn’t sit that flush on to the assembly.

  2. But I am sure the sound is from the movement of the slider assembly on the lead screw.

  1. Nope the sound is too loud and its from the lead screw only.
  2. From my observation I feel that the grease gets pushed onto one side hence there is squeaking sound when the bed moves in the opposite side of the viewer
  3. Funny thing is that when the bed moves towards the user there isn’t any sound, when I home the machine there is no sound since the bed moves towards the user.
  4. But while printing there is sound even at slow speeds when the bed moves backwards.

  1. I Checked the reference link that you shared it says to use a plastic gear grease for noise cancellation and belongs to a specific brand named Japan’s Maeda NIKI FG-107M
  2. Can you please suggest a more generic brand name along with the specifications to source the product locally with similar specs?
  3. We are based in Mumbai, India.

Appreciate all your help and feedback Chris!

If you scroll through the linked post, another user wrote any lithium grease would fit the purpose.
