hidden quest
As you can see from the picture, the belt shaving appear only on the B motor. I've adjusted the gear and locktited but after a 12 hour print the problem persists...
I have double check the belt is not rubbing the panel on the back side, and I have adjusted the gear with the alignment tool and loctite grub screws. Im stumped as to what could be causing the belts to rub the wrong way.
Has anyone else encountered similar problems?

I have had this on a micron 180 before for two seperate (but they ended up linked) reasons
Essentially the back panel was pushing onto the belt path, and also by extension pushing the foam tape into the path of said belts.
This caused belt wear, but also a tonne of little foam shavings which would cling to the XY belts and be seen as far forward as the idler on one side.
I fixed it by using deeper wall panel clips along with taller rubber weather strips which did not get pushed into the belt path.
It might not be the same in your case, but I thought I’d mention it just on the off chance it is.
Tl;dr check that the belts aren’t biting into the foam strips on that side during movement.

Can you tell if the shavings are from the top, bottom or inside (teeth) are wearing? It could be a belt riding slightly off and it's not riding in the center of the GT2 pulley. Try slowly moving your X beam front to back looking for any binding or something causing it to be off center on the pulley. Could be one of the adjacent pullys cause it to be misaligned.

Those kinds of issues are often a bit hard to troubleshoot. The "belt dust" will end up in one or two spots, but the actual problem can be one or two pulleys/idlers over, causing the belt to be misaligned and riding up on the edge of some idler or rubbing.
