The bearing that is in my heat bed that my back z axis lead screw goes into is bad. Bambu sent me the lead screw and the bearing but they don’t have a wiki on how to get the lead screw out as it’s not a common part. Ive tried googling removing the lead screw but can’t find anything on how to do it.
I was able to pull the pulley at the bottom however the bearing at the bottom of the lead screw will only push up, so it seems I can’t pull the lead screw from the bottom.
Looks like if that top covering that goes over the top of the z screw would come off I could easily pull the lead screw and replace it. The bad thing is it looks like that covering has everything in the machine attached to it. Is that the only way to get to the back z screw to pull it and replace it?
