I am using corexy setup with 2mm thick m.s plate. When moving X and Y, it us creating a lot of sound. I am using IGUS 12mm linear guides. When moving with hand, sound is some what less, but with motors, it is giving huge noise. How to solve this issue
That sounds like resonance of the stepper motors. I suggest to use finer microstepping or TMC2100 based drivers. Eventually you should decoupple the steppermotors from the frame by rubber buffers.
The bullets roar in the bearing, they must grease them.
What microstep size are you using?

@Jakab_Gipsz i hope greasing is not required for IGUS linear guides
Greasing is not require only for Igus polymer bearings. But it is also recommended if it is possible aka not problematical as in food and packaging industry were you can have grease contamination on the product.
@Tech_World what microstep size? Full step, half step, quarter step; 1/8, or 1/16? You would need to know this to calculate steps/mm.
@George_Novtekov best thing to do is check the datasheet. A lot of igus products are intended to run dry, and lube gives up some of the benefits.
@Tech_World once again I say it needs to be greasy.
The balls are loud without lubricating. vibrating, resonating.
Metal on the metal without lubrication is not good …
Believe me, I’m over this!
@Jakab_Gipsz You are wrong! He uses Igus T-Rails with Drylin guiding carriages. They do not contain balls and are made for dry run!
The sound we hear is comming from the stepper motors that are screwed to the metalsheet frame, which is a big resonator.
@Ryan_Carlyle We use 1/16 and we changed the steps/mm as per the calculation. THis IGUS is intended to run dry only.
@cprezzi HOw to avoid the resonation? Any idea?
@Tech_World I hear two kinds of noise:
- The stepping of stepper motors
- Resonance of other unresolved things
The first is to set microstep to 64 (if supported by the mainboard)
the second should be secured to all loose parts, loose screw, and tighten the belts.
At the beginning you can hear the linear rail of the x axis. As I have already said, this is caused by the resonance of the ball bearings and by passing lubrication.
It also makes a big difference if you put a flexible (sound absorbing) material around the entire printer:
- plastic foam
- Felt Discs
- bubble film in several layers
@Tech_World I see two ways to reduce the noise: mechanical and stepper drivers.
Silent stepper drivers like the TMC2100 would probably be the easyer way. They produce much less noice because the produce soft transitions between stepps.

The mechanical solution takes more effort. You could try to attenuate the oscilation of the top plate by stiffing it and decouple the motors from the plate. See https://www.aliexpress.com/item/5Pcs-Stepper-Motor-Vibration-Damper-Shock-Absorber-For-Nema-17-3D-Printer/32843679594.html

@Jakab_Gipsz there are no ball bearings. He’s using dry sliding polymer bearings.
I agree with @cprezzi — you should consider stepper damper mounts or a driver chip that can run finer microstepping or a quiet running mode
@Ryan_Carlyle You’ve seen this:
Because I see in the video!
This is called a linear rail, and is full of tiny metal balls that resonate dryly

@Jakab_Gipsz https://www.igus.com/drylin/rail-guide The poster said multiple times that he is using igus rails, which means POLYMER BUSHINGS… igus sells several kinds of linear rails with sliding bearings, no ball bearings.
@Ryan_Carlyle Then I misunderstood. Sorry for this…
