I’ve had to do the x-belt retention thing several times lately and I’m still getting the warning message that it needs tightening. I’ve followed the Bambu guide to do it, including winding the locking bolt out a bit further than they state. (one turn)
The machine has over 2,600 hours on it, does it need a new belt? I also only recently noticed that the belt has no teeth on it, which I’ve not seen before.
