Creaking Sound Ultimaker 2?

[ihackstuff 5]

My printer has been an absolute workhorse! I've literally travelled all over the world and wow.. this printer is amazing. But recently it's started making a creaking noise and I can't figure out where it's coming from or how to fix it. Any ideas? I've oiled the rods, and that didn't seem to help. 

 

Here's a link to a video of the sound: 

 

 

Thanks for any help you can offer!

Hi,

I've no experience with the UM2 (only UM3), but it sounds like a linear bearing of the printhead being the culprit.

Hi @ihackstuff,

 

The video contained a combined x/y movement, -would be much better to hear how it sound doing the full square all four sides only. Then it will be easier to hear if it is X or Y as well.. 😉

 

Thanks (have an UM2E+)

This issue is common on UltiMakers with a lot of love (hours) on them.
Its almost never related to bearings.

The belts are getting worn-out. While it generally does not impact print quality, it does produce this creaking noise.
To fully resolve the issue.. replace all 6 drive belts.

Thanks for the advice! I’ve been shopping for parts since I made the original parts and I’ve only had luck on Ali express (where I found bearings and much more) but there are too many belt options and I’m not sure which ones to get. Can you tell me if these are the right belts? 
 

thank you so much!

Hi @ihackstuff,

 

The four long belts are 2GT610-6.5 (610 is length)

The two short are 2GT200

 

I'll see that this site sell 6 mm wide belts and I tough that the 6.5 meant mm, but they are ONLY 6 mm wide. Just measure mine to be sure..

I'm having a heck of a time finding these belts in 6.5mm width. There are lots of 2GT 610/200 length belts that are 6mm like these and this 2GT 610 search. Does that really matter? I found these 6.5mm 2GT-610-6.5 belts on amazon and they seem like they will work. It seems like all the 3D printer vendors that sell them are charging a fortune because of scarcity, so I'd like to avoid those vendors if it's not really a necessity.

I bought some spare parts from "Robot Digg".

They have all kind of pulleys and lots of standard parts used in UM2 types.

I've got those marked with 6.5 mm, but they really are more close to 6 mm.

6.5 mm is absolutely max width in those pulleys.

 

Well, they are here:
