Noise from carriage

Did you try resetting it? I forget the button sequence now ( I'm at home now ) but you go through the sequence, manually bring the head to the far end and back to reset the position. Surely someone here knows what I mean. Also, I find while cleaning ( manual cleaning) if I happen to put any stress ( press back on the cable a bit by mistake ) I hear a similar squeal, probably from the cable pulling on the head but you may want to check that the cable is not slack. However, I think you would notice it in your print quality and also hear it slapping or ticking if that were the case.
I'm just curious, have you ever had any problems with ink dripping, a small deposit and the far end of the head travel?

 

I think it may have a bit to do with the tension of the cable. You need a tension meter to do it right. I tried to mess with mine to get rid of that noise and got a scary error after, so I set it back to where it was and the error quit..... thankfully. I would say don't mess with it unless you get an error. I know others have the same noise happen and we just deal with it and give it the touch some times.

 

Hi there!

What an annoying sound! You're right about it trying to get to park the head to the proper position. Besides and after adjusting the belt tension you should do an "Limit Initialize setup". This will basically recalibrate the printer's length and capping position.
PM me if you need help with this. You're in my neck of the woods... I visit Renton every now and again!
