Knocking noise when printing

Recommended Posts

Dear Ultimakers,

 

I just bought a new UM2E+, on 1st prints  knocking noise was coming out from the printer. I tried to sense the culprit through touching various part during knocking, but no use. Checked all the belt and there was X axis belt lose & I tighten up, but still knocking sound there.

 

Knocking sound does not appear coming from the feeder.

 

It is definitely coming from the X axis, as I just switched the printer off, and moved the head fast on both X & Y axis's, Y no knocking, while the X showing the same knocking sound when it prints, with knocking specifically been heard at 2 positions.

 

If you divide the X axis to half the sound will be heard on the middle of the right & the left halves. 

 

 

 

Thanks in advance for the help.

Ultimaker UK support suggested this

 

Looks like the print head axis is catching on the 2x Z shafts at the back of the machine. 

 
Please check this by moving the print head left to right and check if the print head axis hits them both.
 
All you need to do is move the print head axis forward so it is not catching. You may need to pop it out of the black sliding blocks to do this. 
 
Unfortunately without a video or guided photos (which I asked the supporter about, said unfortunately he do not have)  its mambo jambo to me.
 
I tried to look online about any demo about fixing the problem, no luck.
 
I am disappointed with Ultimaker support, it should be better than this. (Zortrax is with the best support ever, but their machine not as good as Ultimaker, so I had to let go of Zortrax).

I've got a video for reseating the blocks/printhead shafts: https://ultimakernasupport.zendesk.com/hc/en-us/articles/115004168803-Reseating-Your-Sliding-Blocks 

 

When you reseat them, make sure the Y printhead shaft that runs front to back isn't sticking out beyond the back of the rear sliding block (it will stick out the front; that's fine). The X printhead shaft (that triggers the Y-stop) should be seated far enough to the left that it fully triggers the endstop, but not so far to the left that it scrapes the left panel; I like to leave about a fingernail's width.

    • Taking Advantage of DfAM
      This is a statement that’s often made about AM/3DP. I'll focus on the way DfAM can take advantage of some of the unique capabilities that AM and 3DP have to offer. I personally think that the use of AM/3DP for light-weighting is one of it’s most exciting possibilities and one that could play a key part in the sustainability of design and manufacturing in the future.
