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.
Solution
Update: rebuilt the bearing stack twice. Once with old, once with new bearings. No improvement. So took the whole damn corner apart, realigned everything, and still happened. The only thing I had not done was replace the stepper, so I got a replacement 2504ac, and that resolved it. Maybe the shaft had a little bit of play and it would allow for the belt to go at an angle through the stacks?
