Low noise driving motors

Support & Solutions Hardware Issues

I had an idea of swapping out the old loud whining drive motors to the new low noise ones.

Would they just work if I buy the motors and swap them out or I need to buy also now encoders especially made for the low noise units?

Or maybe encoders are the same and swapping the motors will be as easy as plug and play?

How big is the difference on sound?

Would work. They send these out as replacements currently. It’s noticeably quieter.

@merkswood - who’s your parts supplier?

I asked the local dealer if he can provide the motors and he said that he has the possibility to order them. About 320 euros per one…

Someone has posted a link of a website of Denmark’s dealer. He I believe only ships to nordic countries. But you will get the rough idea what are the current prices of the Yarbo parts.

Here’s the post:

It might not be the motors.

The steppers on the O.G. Ender3 3D printer were loud as heck, sounded like a dot matrix printer from the 80s. The fix was the drivers, not the motors.

Someone else mentioned the cut of the Yarbo’s gears was where the noise came from. You’ll prove that to be true or false if you pull a motor and see what the drive train sounds like, without it. Use a power drill or whatever.

Whatever you find, post back!!!

  1. Original setup: Early Ender 3 printers (and similar Creality models) used basic A4988 stepper drivers. These operate in a mode that causes high-frequency whining, buzzing, or humming from the motors, especially during movement.
  2. The fix: People replaced the drivers or swapped the mainboard for a “silent board” with Trinamic TMC2208/TMC2209 (or similar) drivers. These support StealthChop (or SpreadCycle/StealthChop modes), which uses smoother current control and microstepping for much quieter operation—often making the motors nearly silent.

The gear reduction whine is present when rotating the tracks manually with the unit powered down.

Did this to my ender 3.

Sleeping was a lot less interrupted after that!
