Upper belt binding.

[old escarp]

My printer has been working perfectly fine. All of a sudden I notice a layer shift so I move the tool head around and notice excessive force to move the upper belt. I checked the set screw on the motor and they’re screwed all the way. Is there anything else that could cause the upper belt to bind?

Does it bind at all positions?

I should mention I’m moving it by hand. But when moving diagonally so the bottom belt+hybrids it moves freely. But when moving in the x or y direction the top belt binds consistently

Here’s a video of what’s currently happening

I do print in an enclosure so I’m not sure if one of the bearings went bad because the heat.

Yeah, time to release the belts and see what isn't smoothly turning :/

For sure I have ceramic bearings ready to drop in but I was waiting for more parts to arrive lol. Thanks though!
