I am at an absolute loss. Scratching noise coming from rear motor motor/bearings, V-Core 3.1
So, to troubleshoot this I've:
-Replaced bearing stacks
-Rebuilt and realigned the entire top of the printer. Like completely removed the whole top, resquared it separate from the printer, and replaced.
-Verified spacer shims
-Belts are tensioned to an 85hz strum.
The only thing I haven't replaced, but these are LDO motors that are like... 6 months old? Maybe 8. But I haven't had motors really fail with this noise before.
But yeah, I have no idea what's causing this noise, but the motors are only thing I haven't replaced. Does anyone recognize this noise? If replacing the motors doesn't resolve it I think I'll go crazy 😖

The hell is this clicking?
30 day old bearings (3->3.1 upgrade). Frame is squared to 0.1mm total variance on bed levelling. My theory is that either the belt has some variance that causes it to push up then click off the pulley, or the frame is somehow not square and the belt is not travelling through the motor cage in a linear fashion. Or something. I've spent way too long trying to iron this out.

Clicking noise on x/y axis travel
So, I'm new to Ratrig/Vcore, as I recently picked up a Vcore 3 for a very reasonable price.
I'll start this weekend with really sitting down and making sure the printer is fully squared, then making sure everything's nice and clean and properly set.
Anyways, in my initial testing of the unit, I've noticed this clicking during some movements, and it appears to be coming from the vicinity of the back right motor/roller assembly. My gut tells me bearing, but on a printer I'm not fully knowledgeable in, it could also be many super specific corner cases.
Anyways, attached video of z tilt calibration. You can hear one click right at the beginning, then several clicks in rhythmic order a bit after that as the carriage moves from the second z tilt properly spot.
I'd assume bearing or something wrong with the internals of the back right belt loop madness, but I'm hoping someone here could either confirm that, or point me in a more appropriate direction. Or, tell me I'm being insane and it's not a concern.
