I adjusted the bottom stop and things looked good, but then I found that the bed was not level.
I did try the plastic postal tape and it worked ok, but the ejector caught on it and ripped it up. That problem should go away.
I also noticed that the heated bed started making bubbles under the plastic tape. I am not sure if it was due to the heat interacting with the glue, residual moisture, or just the tape itself.
I will retry the plastic tape after get the bed leveled.
