I attempted to fix it, but there just isn't much left to work with. I think the issue is the result of several of the nuts being missing. The result was holes stretching out. I was watching a video online and noticed that other people had nuts holding the extruder to the bushing assembly. My printer is less than a week old, but already I've found a couple of set screws floating around the bottom. In addition to several missing nuts I didn't find as many set screws as it would take to fill every retaining collar. Is there any chance that some of those aren't necessary, therefore not included?
Also, it appears this part melted and is halfway stuck to the bottom of the motor. Is there any reason why it would be gummy at room temperature?
It seems like the sliders are 8mm. I do happen to have a 8mm pillow block style linear bearing. Is there a better option than completely rebuilding the bearing assembly?
Is there someplace to look to find out more about the glued in slide rods? I haven't been able to find any complete conversation pointing to advantages of going to bearing sliders, but I assume there should be some benefit.
