Got the 3L maybe 4 months ago and it has been well used but very well maintained and only ever operated by me. I noticed about a month ago that a print had stopped about 12% of the way through because the door was open. Odd… it looked closed but was just ever so slightly lifted from the fully closed position. I put a piece of masking tape to tape the door down and that worked. I have continued this ever since. Anyone else have a slightly ajar door all the gd time?
