The first time I tried assembling the z-axis I was only able to get the bearing a few millimeters onto the lead screw before it was completely stuck. I could not hammer it on any further, or hammer it off for that matter. So I ordered another from amazon and tried again and the exact same thing happened. I even tried it a third time and used a little white lithium and it {still} got stuck.
I’m at a loss for what to do here, does anyone have some tips/tricks for this?
