It has been pretty quite since then
I'm having the same issue with the acrylic top piece as well. It bows inward and catches on the feed tubes. I printed like 2 test files and a couple of things I downloaded. I created this cylinder and scaled it as big as I could. It took 13 hours to print. About the last 3 hours the machine developed a clicking noise. It sounds like its coming from the front rod on either side. Almost like plastic gears skipping at the same spot or something. I sent an email to support this morning and still have not herd back from anyone. Does not seem to affect the printing yet but I'm sure there is going to be a failure in the immediate future.
