Belt grabber/adjuster broke. Replaced the adjuster but I have a new noise now.
So while printing, I noticed a layer shift so I stopped printing and inspected. It turns out the belt slipped out the adjuster. I removed the adjuster but in the process of putting the belt back in, I broke it.
I printed a new one on my other printer but now after retensioning the belts, I'm getting a noise coming from the gantry. It sounds like the teeth of the belt are hitting something but I can't see what.
I've tried loosening the belts but the noise is still there.
I've tried loosening the bearing stacks but the noise is still there.
If I pinch the front/top belt against the gantry the noise goes away.
This problem only came up after replacing the belt adjuster. It has been printing fine up until now with no noises.

sounds like your belt leaved the idler stack and is now grinding bc it sits on the flansh
The stack seems to be all tight together. The belt is running between the 2 flanges. Top and bottom belt.
check all iderls
So i reassembled the idlers on the gantry and the front of the printer. It seems to have gone away. Everything was still tight. Unsure what caused it, I was hoping not to spend time on it but I guess I had to. All fixed now. Thanks!
putting the belt back in the tensioner block...if not 'perfect' one edge of the belt can pull tighter than the other (top/bottom). May not be visible but just enough the make the belt want to walk up/down...sounded like the teeth were catching the bearing flange edge. A simple fiddle with the tension might have been all it took to fix it
