Ultimaker 2+ noise?

[gentlemancarrot 0]

Good day, everyone.

 

I purchased a used Ultimaker 2+, it seems to print great and accurate. Even with the stock settings the prints look fantastic. However, it is quite loud with an almost gridding noise. I have included a video link.

 

It doesn't look like anything is rubbing and I lubricated the guide rods.

 

The printer has just over 7000 hours on it and the belts have never been changed. 

 

I am new to 3D printing and only have experience on a much cheaper printer. Any advice would be appreciated.

 

Thanks

Hi, 

 

I had the same sounds (also on an Ultimaker 2+). After changing all the belts the problem was gone.

It's best to also change the glider blocks too, as they can break when you open them.

 

Follow the assembly manual instructions here: https://github.com/Ultimaker/Ultimaker2/blob/master/um2 assembly manual V1.1 _english.pdf

Hi @gentlemancarrot,

 

Welcome in here.

 

According to you video, this sounds like a belt climbing a pulley and looks like the X axis (left right).

 

You could move the head in X, Y or diagonally directions without power (or after a finished print) and observe the belts movement or find the source of this noise.

 

This may occur due to an offset pulley that's forcing a belt hard to one side if the pulley and making this noise.

Often we see black particle collected up in the bottom corner indicating where to look above..

 

Another way is to use a program Pronterface found here:

Use this program when connected to the printer in order to move the head in just one axis by the time, as a detection tools.

 

 

You might just try another com port, say com 6 or around this number and it should connect.

 

Hope this help.

 

Thanks
