Hi Dan,Thanks for the reply and the explanation on this! I didn't post the photo you mentioned but understand now what to look for.
Do you feel it might help by trying to get the tray to sit a little flatter? I was thinking of taking off the tray and clamping it to sit flat for a while hoping the plastic tray will reset to have both of the cam followers sit flat. It's out quite a bit (About an 1/8" ) from the other side. see photo. Thanks again!
