So I just got a used taz 3 and the solid polymer bearing on the bottom right size keeps sliding down and popping off the double bearing holder when moving the z axis. How do I fix this? Kind of new to 3d printing.
You may need to tighten or reprint the bearing holder. Post some pictures hear of the bearing, the bearing holder, and let us know how tightly things are secured on that axis. That’ll help us see what you’re seeing, and it’ll help us make sure we’re dealing with the same model.
